Description
Features:
| CATEGORY | SPECIFICATIONS |
|---|---|
| Product Type | Pyroelectric Human Body Infrared (PIR) Detector Module |
| Model | SR-602 |
| Operating Principle | Pyroelectric infrared detection of human body heat (motion sensing) |
| Detection Distance | Up to 5 m (recommended 0 – 3.5 m) |
| Output Type | Digital signal (HIGH / LOW) |
| Output Voltage | HIGH = 3.3 V, LOW = 0 V |
| Operating Voltage (Supply) | DC 3.3 V – 15 V |
| Quiescent Current | ~20 µA (very low power) |
| Trigger Mode | Repeatable trigger (non-latching, auto retrigger on motion) |
| Delay Time (Output High Time) | Adjustable ~2.5 seconds to 1 hour (factory default: 2.5 s) |
| Blocking Time | ~2 seconds (non-adjustable) |
| Start-up Behavior | Outputs HIGH for ~2 seconds at power-on, then enters standby |
| Sensitivity Adjustment | Adjustable via internal chip resistor |
| Photodiode Support | Optional external photoresistor (LDR) for day/night operation |
| Operating Temperature Consideration | Sensitive to heat sources and sunlight interference |
| Lens / Module Assembly | Pre-soldered lens and pin header |
| Key Features | High sensitivity, ultra-low power consumption, fast response, compact size |
| Installation Notes | Avoid direct sunlight, exhaust heat, and strong radiant sources |
| Safety Note | Use low-voltage soldering tools; disconnect power before soldering |
| Applications | Motion-activated lighting, alarms, security systems, access control, automatic photography, agriculture, forestry, mining automation |
