Raspberry Pi Weather Station Board

This weather station board contains three sensors that measure temperature, relative humidity, and barometric pressure. It connects directly to the Raspberry Pi 26-pin expansion header and communicates via the I2C bus.

Device name: Weather Station Board

Device type: sensor

Connectors: 26-pin expansion header

Measures: temperature, humidity, barometric pressure

Connection class: I2C

Vendor: web4robot

Device Discovery

  • To use this device, you will need to enable I2C support on your Raspberry Pi as described in the Weather Station Board manual. The I2C board address for this device is 0x4e. You can verify that the device is present by running the following command from a terminal:
    •  $ sudo i2cdetect -y 1
         0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
