The Ceiling Mount Microwave Sensor 1L-PS03 is a high-quality, energy-efficient presence-detection solution designed for modern residential, industrial, and commercial applications. Built with a 5.8GHz high-frequency microwave sensing module, this device provides the huge-area detection, superior accuracy, and strong penetration capability compared to traditional Pir Sensor technologies.
The product is a new saving-energy product; it adopts microwave sensor mould with high-frequency electro-magnetic wave (5.8GHz) and combined circuit. It collects automatism, convenience, safety, saving-energy and practical functions. The huge detection field depends on detectors. It works by receiving human motion. When one enters the detection field, it can start the load at once and identify automatically day and night. Its installation is very convenient and its using is very huge. Detection is possible to go through doors, panes of glass or thin walls.
Function:
Can identify day and night: It can work in the daytime and at night when it is adjusted on the “sun” position (max). It can work in the ambient light less than 3LUX when it is adjusted on the “3” position (min). As for the adjustment pattern, please refer to the testing pattern
SENS adjustable: It can be adjusted according to using location. The detection distance of low sensitivity could be only 2m and high sensitivity could be 16m which fits for large room.
Time-Delay is added continually: When it receives the second induction signals within the first induction, it will restart to time from the moment
Time-Delay is adjustable. It can be set according to the consumer’s desire. The minimum time is 10sec±3sec. The maximum is 12min±1min.
NOTE: the high-frequency output of the HF sensor is <0.2mW– that is just one 5000th of the transmission power of a mobile phone or the output of a microwave oven, the body can’t touch it.
Installation: (see the diagram)
Please move the upper cover with anti-clockwise whirl as per the diagram on the right.
Connect the power and the load according to the connection-wire diagram.
Fix the bottom on the selected position with the inflated screw
Install back the upper cover on the sensor, then you could switch on the power and test it.
Applications:-
Main Entrance
Toilet / Pantry
Stairways / Lifts / Lobby
Covered Parking Area
Locker Room / Trial Rooms
Office / ATM / Malls
Warehouses
Schools and institutions
Smart lighting automation systems
Why Choose the 1L-PS03 Microwave Motion Sensor?
Modern Microwave Detection Technology
Instead of conventional Pir Sensor systems that depends on only on infrared changes, it uses Ceiling Mount Microwave Sensor that penetrate thin walls, glass, and wooden partitions. This makes sure an accurate detection even in environments where traditional sensors may fail.
Precise Day/Night Recognition
With an adjustable LUX setting ranging from <3 LUX to sunlight conditions, the device automatically differentiates between daytime and nighttime operation—making sure an energy efficiency without manual intervention.
Fully Adjustable Sensitivity & Time Delay
Customize:
- Detection Distance (1–8 meters)
- Sensitivity Levels (low to high)
- Time Delay (10 seconds to 12 minutes)
This flexibility allows the 1L-PS03 to adapt to small rooms, large halls, corridors, and open spaces.
Safe, Low-Power, Human-Friendly Output
The HF output of <0.2mW is especially safe—just 1/5000th of a mobile phone’s transmission power.
