| Component | Function | |-----------|----------| | | Adjusts output hold time (clockwise = longer) | | Sensitivity (Rx) | Adjusts detection distance (clockwise = more sensitive / longer range) | | Trigger mode jumper (L / H) | L = single trigger, H = repeat trigger | | Temperature compensation (some modules) | Helps reduce false triggers in hot/cold environments |
is a common Passive Infrared (PIR) motion sensor module, widely recognized as an equivalent or specific variant of the
| Pin | Name | Description | |-----|--------|------------------------------------| | 1 | VCC | 4.5V – 20V DC power input | | 2 | GND | Ground | | 3 | OUT | Digital output (HIGH = motion) |
: Do not remove or damage the white plastic dome, as it is critical for the sensor's wide-angle detection.
