RF PIR Sensor = Radio Frequency Passive Infrared Sensor (RF PIR Sensor)
It detects motion by sensing body heat. “Passive” because it doesn’t send out any signal — it just _watches_ for infrared radiation from warm objects like people and animals.
Features:
How it’s different from a regular PIR:
* Regular PIR has a wired output while the RF sends signal wirelessly via RF 315MHz/433MHz
* Regular PIR uses cables to alarm/light while the RF no wires required but battery powered
How it works in 3 steps:
* Detect - Fresnel lens + PIR element sense a warm body crossing detection zones
* Transmit - Built-in RF module fires off a coded signal, usually 433MHz in Nigeria
* Receive - A paired RF receiver, alarm panel, or smart hub picks it up and sounds siren/sends phone alert
