PIR Motion Sensor & 1-Sensor LED Dimmer
The PIR Motion Sensor LED Dimmer combination provides a practical solution for automatic low-voltage lighting control. The concealed PIR sensor detects movement and sends a control signal to the compatible lighting control system.
This setup works well for areas where lights only need to operate when someone enters the space. Common applications include stairs, garages, cabinets, closets, wine cabinets and other indoor areas.
Concealed PIR Motion Sensor Head
The compact PIR motion sensing head provides discreet motion detection without taking attention away from the lighting installation.
The sensor detects movement from approximately 3–4 metres away and provides a 120° detection angle. Therefore, it can monitor a useful area around the installation point while maintaining a compact appearance.
Automatic Motion Detection
When a person enters the sensor’s detection range, the PIR system detects the movement and activates the connected lighting control.
When the person leaves the sensing range, the lighting switches off after approximately 30 seconds.
This automatic operation can make everyday lighting more convenient. It also helps avoid leaving lights switched on unnecessarily in areas that are only used for short periods.
Low-Voltage 5V DC PIR Sensor
The PIR sensor head operates from 5V DC low voltage and provides a 5V level signal output.
This makes it suitable for low-voltage lighting control systems that support the required sensor signal.
Before installation, check the electrical specifications of the sensor and controller to ensure the signal voltage and connection method are compatible.
1-Sensor LED Dimmer
The 1-Sensor LED Dimmer provides constant-voltage control for compatible LED lighting systems.
It supports an input voltage range of 12–48V DC and an output voltage range of 12–48V DC. The dimmer provides up to 8A output current, making it suitable for a range of low-voltage LED applications.
The available maximum output power depends on the operating voltage:
- 96W at 12V
- 192W at 24V
- 288W at 36V
- 384W at 48V
Always ensure that the connected LED load stays within the dimmer’s rated output current and power limits.
Constant-Voltage LED Control
The dimmer uses constant-voltage output, making it suitable for compatible constant-voltage LED lighting products.
This type of control is commonly used with low-voltage LED strips and other constant-voltage LED fixtures.
For LED strip installations, explore our LED Strip Lights range for compatible lighting options.
Automatic Stair Lighting
The PIR sensor and compatible LED control system are particularly useful for stair lighting.
When someone enters the detection area, the sensor can trigger the lighting system. After the person leaves, the lights can turn off after the approximately 30-second delay.
This makes the system useful for stairways where automatic lighting can improve convenience and reduce unnecessary operating time.
Cabinet and Closet Lighting
The concealed PIR sensor also works well for cabinets, closets and wine cabinets.
Instead of searching for a switch, the user can simply open or enter the monitored area. The sensor detects movement and activates the connected lighting system when the installation is configured correctly.
This makes it a practical option for feature storage areas and low-voltage LED cabinet lighting.
Garage and Utility Area Lighting
The system can also provide automatic lighting control in garages, storage areas and utility spaces.
These areas may not require continuous lighting. Therefore, motion-activated operation can provide light when needed and switch it off automatically after the user leaves.

Installation and Compatibility
The PIR sensor and LED dimmer should be installed according to their electrical specifications.
Because the PIR sensor provides a 5V level signal while the dimmer specifications list 12–48V DC input/output, confirm that the dimmer includes a compatible sensor-control input before connecting the two products directly.
Use a suitable power supply for the LED load and ensure the total connected load remains within the dimmer’s rated current and power limits.
Electrical installation should be completed by a suitably qualified person where required.
A Practical Solution for Automatic LED Lighting
The PIR Motion Sensor LED Dimmer system provides a convenient approach to automatic low-voltage lighting control. With motion detection, automatic switching and flexible 12–48V constant-voltage LED control, it can suit a variety of residential and commercial applications.
