This reference design features the TSSP4056 IR sensor module designed for presence and fast proximity sensing applications. The TSSP4056 provides a LOW output when it detects a 56kHz infrared burst at 940nm. It can be easily interfaced with a microcontroller. The device can detect infrared bursts up to 2m for presence and proximity sensing applications. It can operate from a power supply ranging from 2.5V to 5.5V with a 5mA supply current. Read more
