Description 

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 Core 
services , allowing you to securely connect to the device and then collect , process , and analyze the sensor data . 
