Ambient Light Sensor - TEMT6000

Code: MR003-008.2

This ambient light sensor carries the TEMT6000 phototransistor, connected to a pull-down resistor to form a voltage divider that produces an analog voltage output between 0V and +5V as a function of the light detected in the visible spectrum.

Description

This ambient light sensor carries the TEMT6000 phototransistor. The phototransistor is connected to a pull-down resistor to form a voltage divider that produces an analog voltage output between 0V and +5V as a function of the light detected in the visible spectrum. Lower output voltage is an indication of less light detected.

The LED current-limiting resistor is set to deliver approximately 20mA. The current requirement can be met by some microcontroller I/O lines, allowing the sensor to be powered up and down through an I/O line to conserve power.
