Description。The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straightforward to use. The two large， exposed pads function as probes for the sensor， together acting as a variable resistor. The more water that is in the soil means the better the conductivity between the pads will be， resulting in a lower resistance and a higher SIG out. This version of the Soil Moisture Sensor includes a 3-pin screw pin terminal pre-soldered to the board for easy wiring and setup.。To get the SparkFun Soil Moisture Sensor functioning， all you will need is to connect the VCC and GND pins to your Arduino-based device(or compatible development board). You will receive a SIG out， which will depend on the amount of water in the soil. One commonly known issue with soil moisture senors is their short lifespan when exposed to a moist environment. To combat this， we've had the PCB coated in gold finishing(ENIG， or Electroless Nickel Immersion Gold).。Note：Check the Hookup Guide below for assembly and weatherproofing instructions， as well as a simple example project that you can put together yourself!。Get Started with the Soil Moisture Sensor Guide

Description。Get with the times， already! This SparkFun Real Time Clock(RTC)Module is a Qwiic-enabled breakout board for the RV-1805 chipset. The RTC is ultra-low power(running at only about 22nA in its lowest power setting)so it can use a supercapacitor for backup power instead of a normal battery. This means you get plenty of charge and discharge cycles without any degradation to the "battery." To make it even easier to get your readings， all communication is enacted exclusively via I2C， utilizing our handy Qwiic system so no soldering is required to connect it to the rest of your system. However， we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.。This RTC module's built in RV-1805 has not one， but two internal oscillators：a 32.768kHz tuning fork crystal and a low power RC based oscillator and can automatically switch between the two using the more precise crystal to correct the RC oscillator every few minutes. This feature allows the module to maintain a very accurate date and time with the worst case being +/- about three minutes over a year. The RV-1805 also has a built in trickle charger so as soon as the RTC is connected to power the it will be fully charged in under 10 minutes and has the ability to switch power to other systems allowing it to directly turn on or off a power hungry device such as a microcontroller or RF engine.。There is also the option to add a battery to the board if the supercapacitor just isn't going keep your project powered long enough(keep in mind， the supercap can hypothetically make the board keep time for around 35 days)， you can solder on an external battery. That means you can let board sit with no power or connection to the outside world and the current hour/minute/second/date will be maintained.。Note：。The I2C address of the RV-1805 is 0x69 and is hardware defined. A multiplexer/Mux is required to communicate to multiple RV-1805 sensors on a single bus. If you need to use more than one RV-1805 sensor consider using the Qwiic Mux Breakout.。The SparkFun Qwiic connect system is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.

。Description。The SparkFun Continuous Rotation(CR)Servo Trigger is a small robotics board that simplifies the control of hobby RC servo motors. When an external switch or logic signal changes state， the CR Servo Trigger is able to tell an attached servo motor to move from position A to position B. To use the CR Servo Trigger， you simply connect a hobby servo and a switch， then use the on-board potentiometers to adjust the start/stop positions and the transition time. You can use a hobby servo in your projects without having to do any programming!。When we introduced the original Servo Trigger， we mentioned that it could be reprogrammed to be more useful with continuous rotation servo motors. But reprogramming the firmware is somewhat tedious， and users asked for a Servo Trigger preprogrammed with the continuous rotation logic. With this little board you will be provided an easy way to deploy continuous rotation servos into your projects!。The heart of the CR Servo Trigger is an Atmel ATtiny84 microcontroller， running a small program that implements the servo control features designed for continuous rotation servos. On board each of these CR Servo Triggers you will find three potentiometers："A" sets the position the servo sits in while the switch is open， "B" sets the position the servo moves to when the switch is closed， and "T" sets the time it takes to get from A to B and back.。Compared with a servo motor， the CR Servo Trigger board draws very little current， roughly 5mA at 5V. Be sure to note that if you're using the CR Servo Trigger to control your motor， the absolute maximum supply voltage that should be applied is 5.5 VDC. Additionally， the SparkFun CR Servo Trigger is designed to make it easy to daisy chain boards - you can simply connect the VCC and GND pads on adjacent boards to each other.。Note：This idea originally came from our friend in the Oakland area， CTP. If you see him， please give him a high-five for us.。SparkFun CR Servo Trigger Hookup Guide。Features。Recommended Voltage：5VDC。Max Voltage：5.5VDC。Current Draw：5mA。Control Continuous Rotation Servos。Three Control Settings。A - sets the position the servo sits in while the switch is open。B - sets the position the servo moves to when the switch is closed。C - sets the time it takes to get from A to B and back。Easy Control with Potentiometers。Configurable Input Polarity。Configurable Response Mode。Compatible with Analog Servos。ISP Header Pins Available for Reprogram

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. 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 Pulse Oximeter and Heart Rate Monitor Hookup Guide。Features。SparkFun Pulse Oximeter and Heart Rate Sensor。MAX30101 and MAX32664 sensor and sensor hub。Qwiic connectors for power and I2C interface。I2C Address：0x55。MAX30101 - Pulse Oximeter and Heart-Rate Sensor。Heart-Rate Monitor and Pulse Oximeter Sensor in LED Reflective Solution。Integrated Cover Glass for Optimal， Robust Performance。Ultra-Low Power Operation for Mobile Devices。Fast Data Output Capability。Robust Motion Artifact Resilience。MAX32664 - Ultra-Low Power Biometric Sensor Hub。Biometric Sensor Hub Solution。Finger-Based Algorithms Measure Pulse Heart Rate and Pulse Blood Oxygenation Saturation(SpO2)。Both Raw and processed data are available。Basic Peripheral mix optimizes size and performance
