FTLab GDK101 Gamma Radiation Sensor Module

The GDK101 sensor platform allows you to use your GDK101 sensor to monitor radiation levels at your place.

The GDK101 can measure average dose rate per 1 and 10 minutes, it also detect vibrations that can disturb the measurement.

The GDK101 requires setting up I²C for data communication.

Component/Hub

# Example configuration entry
gdk101:
  i2c_id: bus_a
  address: 0x18
  update_interval: 10s

address (Optional, int): Manually specify the I²C address of the sensor. Defaults to 0x18 (A0 and A1 shorted). The address is made up using the state of A0 as bit 1 and the state of A1 as bit 2, so a total of four addresses is possible.
update_interval (Optional, int): Manually defined update iterval of sensor. Default to 60s.
i2c_id (Optional, string): Optional name of the bus.
