The super-smart BME688 air quality sensor can measure temperature, pressure and humidity precisely. It also has an upgraded, AI-enhanced gas scanner! Like its predecessor the BME680, this high quality sensor can be used to monitor every aspect of your...

A really nice environmental sensor that's ideal for indoor monitoring of temperature, pressure, and humidity, or even outdoors in a suitable enclosure. It's Raspberry Pi and Arduino-compatible. We use this sensor on our Enviro+ environmental monitoring...

This light and proximity sensor detects light over a wide dynamic range (0.01 lux to 64,000 lux) and proximity within a short range of ~5cm. The LTR-559 is the same sort of sensor that you'd find next to the camera in your phone to detect when it's next...

An all-singing, all-dancing time of flight distance sensor that uses PEW PEW LASERS (low-powered ones), our VL53L1X breakout is easy to use with Raspberry Pi or Arduino alike! These low-power-laser-based time of flight sensors have great accuracy and...

Measure changes in the concentration of gases including carbon monoxide (CO), nitrogen dioxide (NO2), and ammonia (NH3) with this Breakout Garden compatible I2C breakout. The MICS6814 sensor comprises three semiconductor gas sensors in a single package,...

A fast and precise environmental sensor that can measure temperature, pressure, and altitude. Our BMP280 breakout is Raspberry-Pi and Arduino-compatible. If you're looking for a simple temperature and pressure sensor, then this is the one to pick. It's...

Measure indoor air quality—total volatile organic compounds (TVOC) and equivalent CO2 (eCO2)—with this digital sensor for Raspberry Pi and Arduino. The SGP30 sensor measures two different types of gases: volatile organic compounds (like...

PIR sensors are used to detect motion from pets/humanoids from about 5 meters away (possibly works on zombies, not guaranteed). This sensor is much smaller than most PIR modules, which makes it great for unobtrusive projects. It's also fully-contained -...

An anemometer is a device used for measuring wind speed, and is a common weather station instrument. This well made anemometer is designed to sit outside and measure wind speed with ease. To use, connect the black wire to power and signal ground, the...

The long awaited BME680 from Bosch gives you all the environmental sensing you want in one small package. This little sensor contains temperature, humidity, barometric pressure, and VOC gas sensing capabilities...

This breakout board is the simplest way to create a project with a single "momentary" capacitive touch sensor. No microcontroller is required here - just power with 1.8 to 5.5VDC and touch the pad to activate the sensor. When a capacitive load is...

IR sensor tuned to 38KHz, perfect for receiving commands from a TV remote control. Runs at 3V to 5V so it's great for any microcontroller. To use, connect pin 3 (all the way to the right) to 5V power, pin 2 (middle) to ground and listen on pin 1. It...

Infrared (IR) break-beam sensors are a simple way to detect motion. They work by having an emitter side that sends out a beam of human-invisible IR light, then a receiver across the way which is sensitive to that same light. When something passes between...

If you've ever ordered and wire up a 9-DOF sensor, chances are you've also realized the challenge of turning the sensor data from an accelerometer, gyroscope and magnetometer into actual "3D space orientation"! Orientation is a hard problem to solve. The...

Filling out our accelerometer offerings, we now have the really lovely digital ADXL345 from Analog Devices, a triple-axis accelerometer with digital I2C and SPI interface breakout. We added an on-board 3.3V regulator and logic-level shifting circuitry,...

Bosch has stepped up their game with their new BMP280 sensor, an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. This sensor is great for all sorts of weather sensing and can...

This distance sensor bounces IR off objects to determine how far away they are. It returns an analog voltage that can be used to determine how close the nearest object is. Comes with 12" long 3-JST interface wire. These sensors are good for detection...

Bosch has stepped up their game with their new BME280 sensor, an environmental sensor with temperature, barometric pressure and humidity! This sensor is great for all sorts of indoor environmental sensing and can even be used in both I2C and SPI! This...

If the product is out of stock - please consider the alternative product. This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to...

Adafruit 996 - Brass Liquid Solenoid Valve - 12V - 1/2 Inch G / BSP Thread Control the flow of fluid using the flow of electrons! This liquid valve would make a great addition to your robotic gardening, aquarium, or pool project. There are two...
