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...

This sensor is a temperature detector used to test the liquid temperature based on 18b20. CHARACTERISTICS Standard 3-pin GVS ports are easy to plug. 3V working voltage can drive the micro:bit. The water-proof design makes it possible to use in the...

This is a wind speed sensor with a rain-proof design. It has a standard connector for Octopus brick series products. We can use it to test wind speed. It adopts three half-sphere bowls with a 6CM diameter, presenting 120 degrees branch installation...

A gyroscope is a type of sensor that can sense twisting and turning motions. Often paired with an accelerometer, you can use these to do 3D motion capture and inertial measurement (that is - you can tell how an object is moving!) As these sensors become...

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...
