Are you a maker in the midst of a STEMMA dilemma? This 200mm long 4-wire cable is a fantastic chimera-cable fitted with Adafruit STEMMA QT / Sparkfun Qwiic JST SH on one end, and STEMMA JST PH connectors on the other. You can sand down the center-nub key on the JST PH side to make it fit i..
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 sensor fusion algorithms (..
Add motion, direction, and orientation sensing to your project with this all-in-one 9-DOF sensor that is STEMMA QT ready for easy plug-n-play usage. Inside the chip are three sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gr..
The AHT20 is a nice but inexpensive temperature and humidity sensor from the same folks that brought us the DHT22. You can take sensor readings as often as you like, and it uses standard I2C so its super easy to use with any Arduino or Linux/Raspberry Pi board.This sensor has a typical accuracy ..
This breakout is chock full o' sensors! Add basic gesture sensing, RGB color sensing, proximity sensing, or ambient light sensing to your project with the Adafruit APDS9960 Proximity, Light, RGB, and Gesture Sensor. When connected to your microcontroller (running our library code) it can de..
The Adafruit AS7341 10-Channel Light / Color Sensor Breakout is a multi-channel spectrometer, which is a special type of light sensor that is able to detect not only the amount of light present but also the amounts of light within different wavelengths. This means that you can use it to detect ..
This is the BH1750 16-bit Ambient Light Sensor from Rohm. Because of how important it is to humans and most other living things, sensing the amount of light in an environment is a common place to get started when learning to work with microcontrollers and sensors. Should we turn up the brightness of..
Bosch has been a leader in barometric pressure sensors, from the BMP085. BMP180, BMP280, BMP388... now we've got the next generation, the Adafruit BMP390L (we refer to it as the BMP390) Precision Barometric Pressure and Altimeter Breakout. As you would expect, this sensor is similar to its earli..
Cooling fans...They're everywhere, and they serve the important purpose of keeping things cool, generally electronics. One might rightfully think: "these fans are pretty good at moving air to keep things cool; maybe I can use one of these neat computer fans to keep my widget frosty" fo..
Low cost Lithium Polymer batteries have revolutionized electronics - they're thin, they're light, they can be regulated down to 3.3V and they're easy to charge. On your phone, there's a little image of a battery cell that tells you the percentage of charge - so you know when you abso..
This absolute pressure sensor, ST LPS25HB can quickly and easily measure this air pressure, useful when you want to know about the weather (are we in a low pressure or high pressure system?) or to determine altitude, as the air thins out the higher we get above sea level. For example, at s..
Do you know which way the wind blows? You will now, with this triple-axis accelerometer/magnetometer compass module. Inside are two sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gravity). The other is a magnetometer that ca..
