Environmental Sensor Board (Coral) for Coral Dev Board / Raspberry Pi 

Features

The Environmental Sensor Board is an add-on board (also known as a pHAT or bonnet) that adds sensing capabilities to your Coral Dev Board or Raspberry Pi projects. (It includes an EEPROM for compatibility with Raspberry Pi boards.)  The board provides atmospheric data such as light level, barometric pressure, temperature, and humidity. You can also attach additional sensors with the Grove connectors.  The board also includes a secure cryptoprocessor with Google keys to enable connectivity with Google Cloud IoT Coreservices, allowing you to securely connect to the device and then collect, process, and analyze the sensor data.
