Digital PIR Sensor 3Pin 4x3mm Pyroelectric Infrared Sensor Dual Element - D204S

The D204S is a PIR sensor which integrates digital control circuit and body sensitive element in one electromagnetic shielding. The signal inputs from sensitive element to digital circuit via a high impedance differential. The digital circuit converts the input signal to 15bit ADC digital value. When the PIR signal above the selected threshold, there will be a REL output. The parameter of time are set by resistance to control the time delay of application continuous work. All signals are processed digitally.

• Digital Signal Processing
• Schmidt REL output
• Differential inputs
• Second order Butterworth low-pass filter, removing other higher frequency interference
• High supply rejection, High immunity to RFI
• Output time adjustable, Schmitt REL output for sensitivity
• Lowsupply voltage, Low current consumption
