The difference with the SONOFF PIR2 RF motion sensor is that PIR3-RF has a small and compact size, easy to be used in almost any position to detect movement. SONOFF PIR3-RF motion sensors can detect and report motion. When used for your home security system, it can detect movement within 8M and help identify whether a human or pet is moving around inside your house, and your mobile phone will receive an alert notification. Connect a SONOFF camera or an eWeLink outdoor camera and you can view who is the intruder. When incorporated into your smart lifestyle, the sensor triggers your light on or off after connecting with SONOFF RF Bridge. You can set a scene where the hallway light is turned on when you enter the door. With the universal joint, the sensor can be flexible to rotate at a full 360°horizontal angle and 90°vertical angle which allows you to adjust the sensor into an optimal angle to view everything in your home (The sensor doesn’t move on its own based on your motion). Another convenience for your home is that you can use the sensor for a position where the movement is not easy to be detected via mounting it in the universal joint, and just rotate the universal joint head to get a wonderful detecting angle. Plus, you can directly stick the sensor on the surface of objects to detect movement. Just choose one you like. PIR3-RF has 2 working modes that alert and normal mode. In the alert mode, the sensor is triggered per 5s when someone enters the detection range. In the normal mode, the next alert trigger is activated if there is no motion detected within 1min after the previous detection.

Features:

  1. Motion Sensor & Camera: Binding Alarm notification, by binding a camera, monitor your home on the double insurance.
  2. Alert Mode/Normal Mode: Two built-in modes which are two different trigger time mechanisms to meet your needs in different scenes.
  3. Smart Scenes: Set the smart scenes based on your needs, and trigger more devices/scenes.
  4. Easy Installation: 3M adhesive or screw mounting (universal joint).

Package Includes:

1 x SONOFF PIR3-RF - 433MHZ RF PIR Motion Sensor

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
