Hardware Overview
The ESP32 Environment Sensor Shield incorporates three sensors capable
of measuring five different environmental variables. It also provides
connections for several other sensors that can be connected if so desired.
Onboard Sensors
All of the onboard sensors are connected to the ESP32 via I C connection.
Pressure, Humidity, and Temperature
The first onboard sensor is a Bosch BME280. This sensor measures
relative humidity, temperature, and barometric pressure. On the back side
of the board is a solder jumper (labeled JP1) which can be closed to
change the I C address of the chip. By default the address is 0x77; closing
the jumper forces the address to 0x76.
