DescriptionThe MCP9600 Breakout is a high accuracy Thermocouple Amplifier equipped with an I2C interface， accessed over our Qwiic system. Inside the chip are two temperature sensors， one for the thermocouple itself(the hot junction)and one for the chip itself(the cold junction). As a result， the MCP9600 can read both the ambient temperature and the temperature of whatever you're trying to measure! The MCP9600 can do both with a resolution of 0.0625℃， and an accuracy of ±1.5℃(worst-case). The MCP9600 Thermocouple Amplifier is one of our many Qwiic compatible boards! Simply plug and go. No soldering， no figuring out which is SDA or SCL， and no voltage regulation or translation required!This version of the board comes equipped with screw terminals to allow for your own Thermocouple's wiring to be hooked up with the turn of a screw. This makes it perfect for a variety of applications， from measuring the temperature of your Crock-Pot to making sure your backyard induction furnace is up to temperature.In addition， the MCP9600 has four on-board temperature alerts that you can configure! Instead of constantly polling the sensor over I2C， you can set a temperature limit to trigger an interrupt when the temperature reaches a certain value. This frees up your microcontroller and your I2C bus to do more important things. It's also possible to put the MCP9600 into alternate operation modes in order to save power. The sensor supports a burst mode， where it will take a specified number of samples， return the results， and then go to sleep. This low-power mode makes the MCP9600 perfect for portable applications!We've written an Arduino library to help you get started quickly. You can download the library through the Arduino library manager by searching 'SparkFun MCP9600' or you can get the GitHub repo as a .zip file and install the library from there.The SparkFun Qwiic Connect System is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch， 4-pin JST connector. This reduces the amount of required PCB space， and polarized connections mean you can't hook it up wrong.Get Started with the Qwiic Thermocouple AmplifierFeaturesTemperature Range of -200℃ to 1350℃Four Onboard Temperature AlertsResolution of 0.0625℃Screw Terminal ConnectorADDR Jumper for variable I2C Addresses(default address of 0x60)2x Qwiic Connectors

DescriptionThe SparkFun Pulse Oximeter and Heart Rate Sensor is an I2C based biometric sensor， utilizing two chips from Maxim Integrated：the MAX32664 Biometric Sensor Hub and the MAX30101 Pulse Oximetry and Heart Rate Module. While the latter does all the sensing， the former is an incredibly small and fast Cortex M4 processor that handles all of the algorithmic calculations， digital filtering， pressure/position compensation， advanced R-wave detection， and automatic gain control. We've provided a Qwiic connector to easily connect to the I2C data lines but you will also need to connect to two additional lines. This board is very small， measuring at 1in×0.5in(25.4mm×12.7mm)， which means it will fit nicely on your finger without all the bulk.The MAX30101 does all the sensing by utilizing its internal LEDs to bounce light off the arteries and arterioles in your finger's subcutaneous layer and sensing how much light is absorbed with its photodetectors. This is known as photoplethysmography. This data is passed onto and analyzed by the MAX32664 which applies its algorithms to determine heart rate and blood oxygen saturation(SpO2). SpO2 results are reported as the percentage of hemoglobin that is saturated with oxygen. It also provides useful information such as the sensor's confidence in its reporting as well as a handy finger detection data point. To get the most out of the sensor we've written an Arduino Library to make it easy to adjust all the possible configurations.The SparkFun Qwiic connect system is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.

DescriptionThe SparkFun MicroMod Environmental Function Board adds additional sensing options to the MicroMod Processor Boards. This Function Board includes three sensors to monitor air quality(SGP40)， humidity temperature(SHTC3)， and CO2 concentrations(STC31)in your indoor environment. To make it even easier to use， all communication is over the MicroMod's I2C bus!The SGP40 measures the quality of the air in your room or house. The SGP40 uses a metal oxide(MOx)sensor with a temperature controlled micro hotplate and provides a humidity-compensated volatile organic compound(VOC)based indoor air quality signal. Both the sensing element and VOC Algorithm feature an unmatched robustness against contaminating gases present in real world applications enabling a unique long term stability as well as low drift and device to device variation.The SHTC3 is a highly accurate digital humidity and temperature sensor. The SHTC3 uses a capacitive humidity sensor with a relative humidity measurement range of 0 to 100% RH and bandgap temperature sensor with a temperature measurement range of -40℃ to 125℃. The SHTC3 builds on the success of their SHTC1 sensor with higher accuracy(±2% RH， ±0.2℃)than its predecessor， enabling greater flexibility.The STC31 measures CO2 concentrations based on thermal conductivity and has two CO2 measurement ranges：0 to 25 vol%； and 0 to 100 vol%. The measurement repeatability is 0.2 vol%， with a stability of 0.025 vol% / ℃. The measurement accuracy depends on the measurement range：0.5 vol% + 3% measured value； 1 vol% + 3% measured value. Using measurements from the SHTC3， the STC31 is able to provide humidity-compensated measurements together with improved temperature compensation. The STC31 can compensate for atmospheric pressure too - which is handy if， like us， you're up in the mountains!The outstanding performance of these three sensors is based on Sensirion's patented CMOSens(R)technology， which combines the sensor element， signal processing， and digital calibration on a small CMOS chip. The well-proven CMOS technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.Utilizing our handy M.2 MicroMod connector， no soldering is required to connect it to your system. Simply match up the key on your processor and function board's beveled edge connector to their respective key on the M.2 connector， then secure them to the main board with screws. The MicroMod Environmental Function Board can then be read via the I2C port. The board is equipped with the AP2112 3.3V voltage regulator， I2C pull-up resistors， power LED， jumper to disable the LED， and jumpers for alternative STC31 addresses.Note：A MicroMod Processor and Main Board are not included with this MicroMod Environmental Function Board.

DescriptionThe SparkFun LTE CAT M1/NB-IoT Shield equips your Arduino or Arduino-compatible microcontroller with access to data networks across the globe. This shield adds wireless， high-bandwidth cellular functionality to your IoT project while maintaining low power consumption and small footprint. The SparkFun LTE CAT M1/NB-IoT Shield is based off the Arduino R3's footprint that allows you to easily incorporate it with favorite Arduino-based device.At the heart of the LTE Cat M1/NB-IoT shield is u-blox SARA-R410M-02B LTE Cat M1/NB-IoT modem. Cat M1(Category M1)and NB-IoT(Narrowband IoT)are both Low Power Wide Area Network(LPWAN)technologies that are designed to provide cellular communication to small IoT devices. They operate on LTE network bands just like most smartphones， and should be supported by most cellular network carriers. The u-blox SARA-R4 module communicates over UART via simple AT command set. We've provided library to help you get started with everything from sending SMS text messages to communicating with servers over TCP/IP connection. Additionally， both the module and library support an I2C GPS interface via Qwiic connector， so you can plug in u-blox GPS module and start remotely tracking your project.Each SparkFun LTE CAT M1/NB-IoT Shield also includes ceramic， Molex 1462000001 SMD antenna. The antenna has gain of 3.8dBi around 1.7GHz to 2.7GHz. However， if you would prefer to use an external antenna， we have provided U.FL connector that can be utilized by simply slicing through jumper with hobby knife.Please be aware that there are few extra parts required to get this shield fully functioning， other than an Arduino-based device. First， you'll need to supply your own SIM card， such as this one from Hologram(we do also offer this shield with an included one as well)and your own headers which will need to be soldered on.Note：Be sure to check theHardware Overviewsection in the Hookup Guide for compatible GPS modules. The onboard Qwiic connector is only designed to support u-blox-based GPS modules. It does not support any other GPS modules or sensors.

DescriptionThis sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit(configurable)temperature readings over a 1-Wire interface， so that only one wire(and ground)needs to be connected from a central microprocessor. Power for reading， writing， and performing temperature conversions can be derived from the data line itself with no need for an external power source.Because each DS18B20 contains a unique silicon serial number， multiple DS18B20s can exist on the same 1-Wire bus. This allows for placing temperature sensors in many different places. Applications where this feature is useful include HVAC environmental controls， sensing temperatures inside buildings， equipment or machinery， and process monitoring and control.Note：The pinout for this sensor is as follows：RED=Vcc BLACK=GND WHITE=SIGFeatures3.0-5.5V input voltage-55℃ to +125℃ temperature range±0.5℃ accuracy from -10℃ to +85℃Waterproof1 Wire interfaceProbe is 7mm in diameter and roughly 26mm long.

DescriptionThis is the SparkFun RFM69 Breakout， a small piece of tech that breaks out all the pins available on the RFM69HCW module as well as making the transceiver easy to use. The RFM69HCW is an inexpensive and versatile radio module that operates in the unlicensed ISM(Industry， Science and Medicine)radio band. It's perfect for building inexpensive short-range wireless networks of sensors and actuators for home automation， citizen science and more.This RFM69HCW operates on the 434MHz frequency and is capable of transmitting at up to 100mW and up to 300kbps， but you can change both of those values to fit your application. For example， you can maximize range by increasing the transmit power and reducing the data rate， or you can reduce both for short-range sensor networks that sip battery power. At full power and with simple wire antennas， we can get messages from one side of a large office building to the other through numerous internal walls. In open air you can reach 500 meters or more. With more complex antennas and modulation schemes， similar parts have successfully transmitted from space to the ground(by very smart amateur radio enthusiasts； your mileage may vary)!The RFM69HCW uses an SPI(Serial Peripheral Interface)to communicate with a host microcontroller， and several good Arduino libraries are available. It supports up to 256 networks of 255 nodes per network， features AES encryption to keep your data private， and transmits data packets up to 66 bytes long.SparkFun sells two versions of the RFM69HCW：a 915MHz version and this 434MHz version. Although the ISM band is license-free， the band itself is different in different areas. Very roughly， 915MHz is for use in the Americas， and the 434MHz version is for use in Europe， Asia and Africa. Check your local regulations for other areas.Get Started with the RFM69HCW Hookup GuideFeaturesTransmit power：-18dBm(0.016mW)to +20dBm(100mW)in 1dBm stepsReceive sensitivity：down to -120dBm at 1.2kbpsModulation types：FSK GFSK MSK GMSK OOKBit rates(FSK)：1.2kbps to 300kbpsVoltage range：1.8V to 3.6VCurrent consumption：0.1uA sleep， 1.25mA standby， 16mA receive， 130mA transmit(max)Encryption：AES 128-bit(optional)Packet buffer(FIFO)：66 bytes0.8"×1.1"
