BX604 Pyroelectric Infrared Sensor - 副本
BX604 pyroelectric infrared sensoris integrates a digital intelligent control circuit and a human
detection sensor in an electromagnetic shielding housing. The human body detection sensor couples the sensed human movement signal to the digital intelligent integrated circuit chip through a very high impedance differential input circuit, which converts the signal into an ADC digital signal, and when the PIR signal exceeds the selected digital threshold, there is a timed REL level output. The OEN enable allows the
REL output to be automatically controlled via a light sensor. The sensitivity and time parameters are set by a voltage divider resistor. All signal processing is done on the chip.
