This circuit detects infrared radiation from human or animal bodies with PIR (pyroelectric infrared sensor) and fresnel lens (circular and flat) for increasing efficiency. Ideal for applying with voice recording (such as MXA075), alarm (such as MXA081), and advertising media system.

FEATURES:
- Power supply : 5VDC.
- Consumption : 1mA (standby), 3mA (working).
- Detection range : 3m. (circular len) or 4m.(flat len).
- PCB dimensions : 1.34x1.83 in. (main circuit board) 0.86x0.95 in. (sensor board)
