Infrared Remote Receiver
Model Number: HSIR38S2
Introduction:
HS-IR infrared receiving chip is a small convenient infrared remote receiver widely used. The circuit is made of PIN PHOTODIO and integrated circuit with function of receival, enlarge, automatic gain control, filter the waves and signal normalization output.
The demodulated output signal can directly be decoded by a microprocessor.
For intensifying anti-jamming, all parts pack up in the cambered structure epoxy resin.
HS-IR is compatible with TTL and CMOS; It can neatly receive frequency; It has protection of opposite direction EMI; it has high sensitivity and long distance receiving.
Low voltage and low power consumption.
