These sensor modules are based on Vishay's TSSP77038 modulated infrared receivers. Unlike most IR receiver modules designed for remote control of devices such as televisions, the TSSP77038 has a fixed gain (sensitivity) that makes the sensor more predictable when used in proximity or reflection sensors. The Pololu carrier module combines the TSSP77038 with an IR LED driven by a 555 timer base circuit to form a complete sensor module that requires only a 3.3V to 5V power connection. An enable input allows control of whether the IR LED is lit or not, and a digital output indicates whether an object is detected or not. The module is available in low brightness and high brightness versions that provide detection ranges of up to approximately 30 cm (12 inches) or 60 cm (24 inches). Actual performance depends on many factors, including object size, reflectivity, and ambient light conditions.
