CJMCU-TEMT6000 An Ambient Light Sensor

Looking for Temt6000 Sensor? CJMCU-TEMT6000 An Ambient Light Sensor is available at Zbotic with fast shipping across India.

This CJMCU-TEMT6000 An Ambient Light Sensor module uses a special ambient light detector（TMET6000） with a spectral response that closely emulates the human eye. It helps you to detect the light density and reflect the analog voltage signal back to the Arduino controller. You can set the threshold of a voltage level to trig another unit on the Arduino project.

CJMCU-TEMT6000  is an ambient light sensor is a silicon NPN epitaxial planar phototransistor in a miniature transparent 1206 package for surface mounting. It is sensitive to visible light much like the human eye and has peak sensitivity at 570 nm. While this device is very sensitive to ambient light, but which inhibit infrared (IR) spectrum, which can provide similar “to the human eye, ” the visible spectrum greater responsiveness.

APPLICATIONS:

Ambient light sensor for control of display backlight dimming in LCD displays and keypad backlighting of mobile devices and in industrial on/off-lighting operation.
