Sensors are the eyes and ears of electronics, they monitor external stimuli such as sound, light, pressure, and heat, and convert them into signals for your microcontroller to process.
We've got all kinds of sensors available for your project, so make sure that you pick the correct one for your hardware. If you get stuck, be sure to reach out to us via our forum.

Weather
How's the weather? Well, you may never know without some sensors for your next project, and we've got both analog and digital options covered.
- PiicoDev Pressure Sensor MS5637Measure barometric pressure or infer altitude-change from air pressure.
- PiicoDev Atmospheric Sensor BME280The PiicoDev® Atmospheric Sensor allows you to easily measure barometric pressure, humidity, and temperature. Use it to build your own weather station or perform experiments.
- DHT22 Temperature and Relative Humidity Sensor ModuleThe DHT22 is a step up from the older DHT11 and has some improved features.
- DHT11 Temperature and Relative Humidity Sensor ModuleThe module can detect surrounding environment of the humidity and temperature.
- GY-68 BMP180 Digital Pressure Sensor Module (Replaces BMP085)SKU: 018-GY-68 Brand: Core ElectronicsThe BMP180 is the BMP085's successor and brings to the table more accuracy, better energy consumption and smaller form size. There are plenty of example tutorials and guides for the BMP180; help by the fact it's a drop-in replacement for the BMP085.
- Soil Moisture Sensor (Arduino Compatible) Immersion GoldThe new soil moisture sensor uses Immersion Gold which protects the nickel from oxidation. Electroless nickel immersion gold (ENIG) has several advantages over more conventional (and cheaper) surface platings such as HASL (solder), including excellent surface planarity (particularly helpful for PCB's with large BGA packages), good oxidation resistance, and usability for untreated contact surfaces such as membrane switches and contact points.
- Temperature Sensor - Waterproof (DS18B20)SKU: SEN-11050 Brand: SparkfunThis 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.
