220V AC PIR Microwave Radar Infrared Auto Sensor Switch

220V AC PIR Microwave Radar Infrared Auto Sensor Switch

Upgrade your home or office lighting with this intelligent 220V AC 50Hz Auto Infrared Sensor Switch. Combining PIR (Passive Infrared) and microwave radar detection technologies, this compact module automatically activates connected lights or devices when motion is detected — and switches them off when the space is empty. It's an energy-smart, hands-free solution for hallways, stairwells, garages, storage rooms, and more.

Key Features

• Dual Detection Technology: Combines PIR infrared sensing with microwave radar for highly accurate, reliable motion detection.
• Adjustable Detection Range: Covers approximately 3–6 meters, with adjustable sensitivity to suit your space.
• Adjustable Time Delay: Customize how long the connected device stays on after motion is last detected.
• SCR Output Mode: Silent, reliable solid-state switching — no mechanical relay noise.
• Ultra-Low Standby Power: Consumes less than 0.5W in standby, making it highly energy efficient.
• 220V AC / 50Hz Compatibility: Designed for standard mains voltage used across Europe, Asia, Australia, and more.
• Compact Module Design: Easy to integrate into existing light fittings, junction boxes, or DIY smart-home projects.

Frequently Asked Questions

Q: What is a PIR microwave radar auto sensor switch and how does it work?

A: A PIR microwave radar auto sensor switch combines two detection technologies — passive infrared (PIR) sensing and microwave radar — to detect movement within a set range (3–6 meters). When motion is detected, the switch automatically activates the connected electrical load (such as a light). After a user-defined delay with no movement detected, it switches the load off again, saving energy automatically.

Q: What voltage is this sensor switch compatible with?

A: This sensor switch is designed for 220V AC at 50Hz, which is the standard mains voltage used in Europe, the UK, Australia, Asia, and many other regions. It is not compatible with 110V AC systems without a step-up transformer.

Q: Can I adjust the detection range and time delay on this sensor switch?

A: Yes! Both the detection range (approximately 3–6 meters) and the time delay (how long the connected device stays on after motion stops) are adjustable, allowing you to fine-tune the switch's behavior to perfectly suit your specific space and needs.

Q: What does SCR output mode mean?

A: SCR stands for Silicon Controlled Rectifier. It is a type of solid-state electronic switch that controls the output with no moving mechanical parts, resulting in silent, smooth, and long-lasting operation compared to traditional relay-based switches.

Q: Is this sensor switch energy efficient?

A: Yes. The standby power consumption is less than 0.5W, making it an extremely low-power device when no motion is present. Combined with its automatic on/off functionality, it helps reduce unnecessary electricity usage in any space.
