qxrs001 pyroelectric infrared human body induction processor

qxrs001 is a pyroelectric infrared sensor signal processor with high performance. it is equipped with a pyroelectric infrared sensor and a small number of external components to form a passive pyroelectric infrared switch.

qxrs001 has a built-in two-stage high-gain, high-input impedance operational amplifier, which can be matched with a variety of sensors for signal preprocessing; qxrs001 also has a 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 rates.

qxrs001 can make various settings by adjusting the peripheral circuit: adjust the sensitivity of the sensor, set the signal trigger blocking time and output delay time, select the repeatable and non-repeatable trigger working mode, set the light control function, etc., the circuit debugging is flexible and convenient, and can be adapted to many different applications.

qxrs001 adopts sop16 package.
