TMD2771X ALS Infrared IR LED Optical Proximity Distance Detector Module Ambient Light Proximity Sensor IR LED 3-in-1 Sensor For Arduino

Description:


This TMD2771X sensor has 3 features: ambient light, proximity sensor and infrared IR LED. It plays a main role in mobile phone about two aspects.

First, this sensor is applied to detect the current brightness of ambient light, adjust automatically the brightness of backlit with software according to
the current brightness of ambient light to adapt to ambient brightness, and make the brightness of backlight gentle to protect vision and save power.

Second, that is proximity sensor. It judges whether the mobile phone is close to face by the reflex of LED launching infrared and the reception of
built-in PD, and thereby determined the status of backlit and touch screen button ON / OFF.

The biggest advantage is that it is integrated with the infrared emission tube, no need for external support of LED. Besides, this 3-in 1 sensor has
integrated transceiving and minimized design without limitation of space. And Its structure is simpler.

Package included:

1 × Sensor
