DescriptionThis straight bar load cell(sometimes called a strain gauge)can translate up to 10kg of pressure(force)into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to， and proportional of， the strain(e.g. pressure or force)applied to the bar. With this gauge you will be able to tell just how heavy an object is， if an object's weight changes over time， or if you simply need to sense the presence of an object by measuring strain or load applied to a surface.Each straight bar load cell is made from an aluminum-alloy and is capable of reading a capacity of 10kg. These load cells have four strain gauges that are hooked up in a wheatstone bridge formation. The color code on the wiring is as follows：red = E+， green = O+， black = E-， and white = O-. Additionally， these load cells offer an IP66 protection rating and feature two M4 and two M5 sized through-holes for mounting purposes.Get Started with the Load Cell GuideFeatures80mm×12.7mm×12.7mm， 250mm Wire

DescriptionThe Pi Zero USB Stem is a PCB kit that turns a Raspberry Pi Zero into a USB dongle. Once the Stem is installed， your Raspberry Pi can be plugged directly into a computer or USB hub without any additional cables or power supplies. The Raspberry Pi then acts as a USB device using its own Linux kernel gadget drivers to get started.The Zero Stem is designed to be soldered directly to the USB SMD test pads on the bottom of the Raspberry Pi Zero， needing no wires or pogo pins at all， just solder and a soldering iron! Attaching the stem to your Pi also allows you to create a portable VNC server， or even cluster several Raspberry Pi Zeros with just a USB hub.The Zero Stem is compatible with the Raspberry Pi Zero v1.3 and the Raspberry Pi Zero W v1.1， but unfortunately it is not compatible with the Raspberry Pi Zero v1.2 or any full-size Raspberry Pi due to their shapes and sizes.Note：In order for your Pi Zero to function as a USB device with this Stem， you will need to configure it to act as one. You will be able to find these instructions in the Documentations tab under "How to OTG Fast".

DescriptionThe 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

DescriptionPassive Infrared(PIR)sensors are great for detecting motion in a small area around the sensor. The 170μA SparkFun EKMC4607112K PIR Breakout is a simple board equipped with an EKM-series PIR sensor from Panasonic(R). The EKM-series PIR sensors are optimized for small movements to offer motion-sensing options for continuously powered applications.PIR sensors do not return specific distance data but instead monitor for IR light coming from objects in their field of view and will activate their signal when motion is detected in their sensing area， making them perfect for applications such as turning devices on automatically when motion is detected. Applications include home and building automation for energy saving， automated on/off lighting control， security， appliances， and IoT.Panasonic's low-profile PIR motion sensors(10.9mm versus standard 14.4mm height offer space savings for constrained designs)consist of a lens to create various detection zones， an optical filter to block non-infrared light， pyroelectric sensing elements， electromagnetic shielding to all circuitry， and an impedance converter to get an electrical signal. This PIR sensor offers digital output across 32 zones at 5m detection distance with 90°×90° detection area.Note：The sensitivity of passive infrared sensors is influenced by environmental conditions， so a performance evaluation test under representative conditions is recommended.Get Started with the SparkFun PIR Breakout GuideFeaturesOperating Voltage：2.3-4.0V170 μAstandby current consumptionLens diameter - 10.4mmLens Height - 10.9mm5m detection distance90°×90°(±45°)detection area

DescriptionWe all like to know the temperature， right? Well， with the SparkFun TMP102 Digital Temperature Sensor， we've made it just about as easy as it gets. Based on the original Digital Temperature Sensor Breakout TMP102， we've added Qwiic connectors to bring this board into our plug-and-play Qwiic Ecosystem and added an address jumper instead of breaking out the address pin. However， we still have broken out 0.1"-spaced pins in case you prefer to use breadboard.The TMP102 itself is an easy-to-use digital temperature sensor from Texas Instruments. While some temperature sensors use an analog voltage to represent the temperature， the TMP102 uses the I2C bus of the Arduino to communicate the temperature.The TMP102 is capable of reading temperatures to resolution of 0.0625℃， and is accurate up to 0.5℃. The breakout has built-in 4.7kΩ pull-up resistors for I2C communications and runs from 1.4V to 3.6V. I2C communication uses an open drain signaling， so there is no need to use level shifting.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 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 TMP102 Digital Temperature Sensor GuideFeaturesUses the I2C interfaceI2C Address：0x48 by default(Three additional addresses available， as well)12-bit， 0.0625℃ resolutionTypical temperature accuracy of ±0.5℃3.3V sensorSupports up to four TMP102 sensors on the I2C bus at time2x Qwiic Connectors

DescriptionThe SparkFun Inventor's Kit(SIK)for Arduino Uno is a great way to get started with programming and hardware interaction with the Arduino programming language. The SIK includes everything you need to complete five overarching projects consisting of 16 interconnected circuits that teach everything from blinking an LED to reading sensors. The culminating project is your very own autonomous robot! No previous programming or electronics experience is required to use this kit.The online guide contains step-by-step instructions with circuit diagrams and hookup tables for building each project and circuit with the included parts. Full example code is provided， new concepts and components are explained at point of use， and troubleshooting tips offer assistance if something goes wrong.The kit does not require any soldering and is recommended for beginners ages 10 and up who are looking for an Arduino starter kit. For SIK version 4.1 we took an entirely different approach to teaching embedded electronics. In previous versions of the SIK， each circuit focused on introducing a new piece of technology. With SIK v4.1， components are introduced in the context of the circuit you are building， and each circuit builds upon the last， leading up to a project that incorporates all of the components and concepts introduced throughout the guide. With new parts and a completely new strategy， even if you've used the SIK before， you're in for a brand-new experience!This version of the SIK replaces the SparkFun RedBoard Qwiic with the Arduino Uno(SMD version)and comes without the SIK guidebook and carrying case. With these components being swapped and removed， we were able to reduce the overall size and weight of the kit， making shipping cheaper and easier for anyone ordering internationally.Note：As stated above， this SIK does NOT include a carrying case or print guidebook.Get Started With the SparkFun Inventor's Kit v4.1 Experiment GuideExamplesProject 1：LightCircuit 1A：Blinking an LEDCircuit 1B：PotentiometerCircuit 1C：PhotoresistorCircuit 1D：RGB Night-LightProject 2：SoundCircuit 2A：BuzzerCircuit 2B：Digital TrumpetCircuit 2C："Simon Says" GameProject 3：MotionCircuit 3A：Servo MotorsCircuit 3B：Distance SensorCircuit 3C：Motion AlarmProject 4：DisplayCircuit 4A：LCD "Hello， World!"Circuit 4B：Temperature SensorCircuit 4C："DIY Who Am I?"

DescriptionOne ruler to rule them all. This is a basic 12 inch ruler， but made from a PCB. We have included a lots of useful information on each side of the ruler that you might use on a daily basis including Wire Gauge holes， transistor diagrams， common fractions， Roman numerals， and metric to imperial conversions. Most importantly， the ruler provides you with a straight line and centimeter markings one side and inch markings on the other side.You'll also find a small protractor in the middle for all your angle measurement needs. While we figured you have a fairly good idea how to use a ruler we do have a tutorial to explain all the information you'll see!Get Started with the How to use a Ruler GuideFeatures12 inch PCB ruler with markings down to 0.05" or 1/32"30.48 cm PCB ruler with markings down to 0.1mmElectrical Equations such as Ohm's Law and Parallel ResistorsKeyboard Alt CodesColor WavelengthsProtractorMetric Prefix Summary ChartMetric conversionsMorse CodeTransistor DiagramsRoman NumeralsFraction SummaryWire Guage ChartTap and Drill ChartSize：12"x 1.5"
