#28, C1: Ambient Light Sensor
Function: Visible spectrum ambient light sensor
Form factor: C1
Special needs: Tibbit #00-3
Power requirements: 5V/2mA

Details
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.
This C1 device requires the Tibbit #00-3 to be installed in the neighboring "M" Tibbit
socket. #00-3 provides two direct lines for I2C comms, as well as the ground and
+5V power for the BH1721FVC IC.
Sample project
The use of this Tibbit is illustrated by a Tibbo BASIC test project. Yo can find it
