Description

ZRD09 Pyroelectric Infrared Sensor Module Intelligent Thermal Sensing Human Body Sensing Switch Element

  1. Product Features:

  3. 1. Pyroelectric PIR core + Fresnel lens for reliable human motion detection with low false triggers.
  4. 2. Wide 5–20 V DC input and ultra‑low static current (≤55 μA) for battery‑powered devices.
  5. 3. Repeatable/non‑repeatable trigger modes and adjustable time delay (5 s–10 min) for custom behavior.
  6. 4. Optional photo‑resistor interface for light‑activated sleep (e.g., off during daylight).
  7. 5. Built‑in voltage regulation and noise suppression for stable output in harsh environments.

  8. Applications:

  9. 1. Smart Home Switches/Lighting: Auto‑on/off for hallway lights, bathroom fans, and under‑cabinet lighting.
  10. 2. Security Alarms: Core detector for home/office burglar alarms and perimeter monitoring.
  11. 3. Industrial Automation: Hands‑free operation for assembly lines, conveyor belts, and access control.
  12. 4. Energy‑Saving Systems: Occupancy sensing to cut power to idle equipment (vending machines, displays).
  13. 5. Consumer Electronics: Automatic wake‑up for smart displays, toilets, and small appliances.
  14. 6. IoT Devices: Integration with Arduino/ESP32 for remote motion alerts via Wi‑Fi/Bluetooth.

  15. 7. Compact form factor for seamless integration into switches, lamps, and sensors.
