Cxle87171 is a pyroelectric infrared signal processor with high performance It is equipped with a pyroelectric infrared sensor and a small number of external components

Cxle87171 has built-in two-stage high gain, high input impedance operational amplifier, which can match with a variety of sensors for signal preprocessing; cxle87171 also has built-in high-precision reference power supply and bidirectional amplitude discriminator, which can effectively suppress power supply and environmental noise interference, improve system reliability and reduce false alarm rate.
Cxle87171 can be set by adjusting the peripheral circuit: adjusting the sensitivity of induction, setting the signal trigger blocking time and output delay time, selecting the working mode of repeatable and non repeatable trigger, setting the light control function, etc. the circuit debugging is flexible and convenient, and can adapt to many different application occasions
