Features:

ZRD09 (ZRD-09) Thermopile Infrared PIR Sensor Module Parameter Description

Principle: Thermopile effect, integrated PIR sensitive element + dedicated signal processing chip + Fresnel lens, **analog level output**, human movement detection, wide voltage supply, supports two trigger modes, built-in light-sensitive control reserved circuit, mostly used for human detection lights, security alarms

Core Detection Parameters

- Detection Wavelength: 5~14 μm (human infrared band)
- Sensing Distance: 4~8m (adjustable, dependent on Fresnel lens)
- Sensing Angle: 100° (determined by lens)
- Output Level: High level 3V, low level 0V
- Delay Time: 3~300s adjustable continuously (time for output to remain after human leaves)
- Lockout Time: Default 4s (4s after triggering, to prevent false triggering)
- Trigger Mode: **Repeatable Trigger / Non-repeatable Trigger (selected by pin configuration)**

Electrical Parameters

- Supply Voltage: **DC 5V ~ 20V** (wide voltage)
