This SMT PIR sensor have 3 versions—3, 4 & 6 terminals. All the signal processing is made digitally. The voltage levels in the input, converted to a digital values ( 7 bit ). The PIR signal is converted to 15 bits digital values on the chip. There is a light indication when PIR signal is above the threshold.

New PIR digital sensor with delay time adjustments and an expanded range from 2 seconds to 70 minutes. The unit includes an integral light sensor with adjustable sensitivity. It is suitable both for outdoor and indoor mounting.

This new PIR sensor integrates digital control circuit and body sensitive element in one electromagnetic shielding. All signals are processed digitally. The signal inputs from a sensitive element to digital circuit via a high impedance differential. The digital circuit converts the input signal to a 15 bit ADC digital value.
