#28, C1: Ambient Light Sensor
|Top Previous Next|
Function: Visible spectrum ambient light sensor
Form factor: C1
Special needs: Tibbit #00-3
Power requirements: 5V/2mA
This Tibbit is based on the BH1721FVC ambient light sensor with I2C interface. The sensor is implemented as the C1 device with a clear (transparent) window. The module measures the light intensity of the surrounding environment and its spectral response is close to that of a human eye.
The module outputs ambient light measurements as 16-bit values that do not correspond to any standard measurement units.
The use of this Tibbit is illustrated by a Tibbo BASIC test project. Yo can find it here: https://github.com/tibbotech/CA-Test-Tibbit-28.
