Google Environmental Sensor Board for Coral Dev and Raspberry Pi

Download Environmental Sensor Board Datasheet

Getting Started and Python API Reference

Google Coral Environmental Sensor Board is the pHAT with a collection of imperative sensors. This board improves the functioning of both Coral Dev and RPi projects. An EEPROM is present on the pHAT which creates its compatibility with the RPi boards. Detection of atmospheric conditions such as humidity, temperature, light level, or barometric pressure can be done by the Google Environmental Sensor Board. More sensors can also be connected to the groove connector of the Coral Environmental Sensor board.
