The Environment Sensor HAT is designed for the Raspberry Pi series of boards, with rich onboard resources including an ambient light sensor, VOC sensor, IR / UV sensor, gyroscope, accelerometer, magnetometer, barometer, temperature & humidity sensor, etc. This hat utilizes the I2C bus for communicating with Raspberry Pi, freeing up valuable GPIO pins for use with other things. The Environment Sensor HAT gives your Raspberry Pi or Raspberry Pi Zero the ability to collect environmental data like temperature & humidity, air pressure, ambient light intensity, VOC, IR ray, UV ray, etc. One fun application would be an environmentally conscious robot that can detect motion and orientation while gathering loads of sensor data at the same time. This would also be a great HAT to prototype a small weather station with.
