smart switch – motion sensor – PIR3-RF – 433MHZ RF Description:

The PIR3-RF Smart Switch with Motion Sensor is a device designed to automatically control lighting and electrical appliances based on motion detection. It operates using 433MHz RF (Radio Frequency), making it suitable for wireless communication with compatible devices. Below is a detailed description:

Key Features:

1. Motion Detection (PIR): Utilizes a Passive Infrared (PIR) sensor to detect the movement of people or animals within a specific range, typically 5-12 meters. The sensor detects infrared radiation emitted by warm objects (e.g., human bodies) as they move in the sensor’s field of view.
2. Wireless Control (433MHz RF): The switch operates at 433MHz RF, allowing for wireless communication with other RF-enabled devices, such as remote controls, smart hubs, or other smart switches. This frequency is widely used for short-range communications.
3. Automatic Activation: Once motion is detected, the switch automatically turns on connected lights or devices. After a set period of inactivity, the switch turns the device off to save energy.
4. Adjustable Sensitivity & Time Delay: Many models allow you to adjust the sensitivity of the sensor to avoid false triggers and customize the delay time before the switch automatically turns off after no movement is detected.
5. Power Supply: The PIR3-RF is typically powered through a standard AC power supply, often requiring AC 110-240V. Some models may include battery backup or use low-voltage DC power.
6. Compact Design: The unit is often compact and can be installed easily in various locations, such as hallways, kitchens, offices, and rooms where hands-free operation of lights or devices is desired.
7. Energy Saving: Since the switch only activates connected devices when motion is detected, it helps save energy by preventing unnecessary usage when no one is present.

• Humidity Resistance: Suitable for typical indoor use (may not be weatherproof unless specified for outdoor use).

Benefits:

• Automatic Control: The motion sensor automatically turns connected devices (like lights or fans) on when motion is detected and off when no motion is present. This prevents devices from running unnecessarily and helps save energy.
• Reduced Power Consumption: The switch operates with minimal power consumption, and since it only activates when needed, it helps cut down electricity bills, especially for devices like lights that are often left on by mistake.
• No Need for Manual Switching: The PIR sensor detects movement and triggers the device without needing to press a button or flip a switch, making it highly convenient for users in rooms where hands-free operation is desired (e.g., kitchens, hallways, bathrooms).
• Ideal for High-Traffic Areas: Perfect for areas where people enter and exit frequently, as the lights or devices will automatically turn on and off based on detected movement.
• Automatic Lighting for Safety: When connected to lighting systems, the switch can enhance security by automatically turning on lights when someone enters the area. This can help deter intruders or provide safety for users moving around in the dark.
• Integration with Security Systems: The motion sensor can be integrated into a broader home security system, triggering alarms or notifying homeowners when unexpected motion is detected.

the PIR3-RF Smart Switch with Motion Sensor is an excellent solution for automating the control of electrical devices, offering a combination of convenience, energy efficiency, and security. By utilizing motion detection and 433MHz RF technology, it enables hands-free operation, ensuring that devices such as lights or fans turn on and off based on motion detection, reducing energy wastage and improving safety.
