Pimoroni PIM745 - A 3-in-1 super sensor suite for environmental, light and movement sensing, with Qw/ST for easy, solderless connectivity. We heard you like sensors (we definitely like sensors!). So we combined three of our favourite ones into...

Detect fourteen distinct channels of light (from 380 nm to 1000 nm) with this versatile spectral sensor. The AS7343 is a 14-channel multi-purpose spectral sensor. It is optimized for reflective, transmissive and emissive measurements including color...

A really sophisticated and accurate colour and luminance sensor breakout that's Raspberry Pi and Arduino-compatible. As well as detecting RGB colour and light level, it has added bells and whistles like 50/60Hz light noise rejection, a wide detection...

Breathe easy, knowing that you can track and sense the quality of the air around you with this Adafruit PMSA003I Air Quality Breakout. This sensor is great for monitoring air quality, in a compact plug-in format. Best of all, unlike almost all other...

Behold, the ST LSM6DSOX: The latest in a long line of quality Accelerometer+Gyroscope 6-DOF IMUs from ST. This IMU sensor has 6 degrees of freedom - 3 degrees each of linear acceleration and angular velocity at varying rates within a respectable range...

Take a deep breath in...now slowly breathe out. Mmm isn't it wonderful? All that air around us, which we bring into our lungs, extracts oxygen from and then breathes out carbon dioxide. CO2 is essential for life on this planet we call Earth - we and...

Add high-quality motion, direction, and orientation sensing to your Arduino project with this all-in-one 9 Degree of Freedom (9-DoF) sensor with sensors from ST. This little breakout contains two chips that sit side-by-side to provide 9 degrees of...

Breathe easy, knowing that you can track and sense the quality of the air around you with the PM2.5 Air Quality Sensor with Breadboard Adapter particulate sensor. Mad Max & Furiosa definitely should have hooked up one of these in their truck...

Add heat-vision to your project with an Adafruit AMG8833 Grid-EYE Breakout! This sensor from Panasonic is an 8x8 array of IR thermal sensors. When connected to your microcontroller (or raspberry Pi) it will return an array of 64 individual infrared...

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 -...

Take your next outdoor sensor project to the next level with this SHT-30 based temperature/humidity sensor. The sensor includes a dual-use sensor module from Sensirion in a sintered metal mesh encasing. The casing is weatherproof and will keep water from...

A wireless climate and environmental monitoring system designed to make hooking up weather sensors a breeze (or a squall, or a gale). Enviro Weather is a super slimline all in one board for keeping a (weather) eye on the great outdoors. The onboard...

A wireless monitoring system to help take good care of your plants. Monitor moisture levels with the soil sensors, or hook up pumps to make a whole auto-watering system! The new Enviro (Pico W Aboard) range is designed with environmental monitoring /...

Sensirion Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. And, finally we have some that have a true I2C interface for easy reading. The SHT31-D sensor has an excellent ±2% relative...
