PIR DIGITAL SENSOR

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.

When the PIR signal above the selected threshold, there will be a REL output. The parameter of time is set by resistance, to control the time delay of the application continues work.

Supply voltage: up to 3.3V
