Proximity Sensor

DESCRIPTION

A proximity infared sensor (PIR) is a sensor able to detect the presence of nearby objects without any physical contact.

PIR sensors often emits an infrared signal and looks for changes in the return signal to detect moving objects. 

This specific reference design utilizes a dual-purpose IC from Silicon Labs which offers ambient light sensing and proximity sensing capabilities in a single device. This exceptionally small integrated sensor provides ease of implementation as it eliminates the design effort required for separate solutions.


DESCRIPTION

Ambient light photo sensors detect the amount of light present within an environment, sending a signal proportional to the amount of light detected to control backlighting and basic on/off light control.
