The WAVE-20471 is a HAT that gives the Raspberry Pi the ability to collect environmental data like temperature & humidity, air pressure, ambient light intensity, VOC, IR ray, UV ray, etc. It can also be used to build a robot that can detect motion and orientation.
The Environment Sensor HAT is designed for Raspberry Pi, with rich onboard resources including ambient light sensor, VOC sensor, IR / UV sensor, gyroscope, accelerometer, magnetometer, barometer, temperature & humidity sensor, and so on. It uses the simple I2C bus for communicating with Raspberry Pi.
Features
