Vishay 红外接近传感器芯片, TSSP94056

The Vishay IR Sensor Module is the latest generation of compact infrared detector module for presence, proximity, or light curtain applications. They provide an active low output in response to infrared bursts at 940 nm. The frequency of the burst should correspond to the carrier frequency.

Presence sensor up to 2 m distance
Light barrier up to 12 m distance
Fast proximity up to 2 m range at 5 ms response time
