Original price was: ₹690.00.₹570.00Current price is: ₹570.00. (+18% GST extra)Product Overview
The 1L-PS23 using modern microwave radar technology to detect the human motion—even through certain non-metallic materials such as glass, thin walls, or wooden doors. This makes the product exceptionally versatile for enclosed indoor spaces, hallways, concealed ceilings, and areas where traditional sensors may fail.
Once motion is detected, the sensor automatically activates the connected lighting or load and resets intelligently based on continuous movement. Its night-and-day detection function makes sure an appropriate activation relative to ambient lighting conditions, managed effortlessly through user-adjustable controls.
The product is a new saving-energy switch; it adopts microwave sensor mould with high-frequency electro-magnetic wave (5.8GHz) and combined circuit. It collects automation, comfort, 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 easy and its using is very huge. Detection is possible to go through doors, panes of glass or thin walls.
Specifications:-

- Time Delay: Min. 10sec±3sec, Max. 12min±1min
- Rated Load: 1200W-300W
- Detection Range: 360°
- Detection Distance: 1-8m (radius), adjustable
- HF System: 5.8GHz CW radar, ISM band
- Transmission Power: <0.2mW
- Installing Height: 1.5-3.5m
- Power Consumption: approx. 0.9W
- Detection Motion Speed: 0.6-1.5m/s
Functions:
- 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 baby can not touch it
Installation : (see the diagram)
- Switch off the power.
- Open the transparent vinyl cover which is at the bottom of the sensor.
- Loose the screws in the connection terminal, and then connect the power and rated load to connection terminal of sensor according to connection sketch map.
- Tighten the screw and put the transparent vinyl cover into the original location
- Fold the metal spring of the sensor upwards, until they are in “I” position with sensor, and then put the sensor into the hole or installation box which is on the ceiling and has the similar size with the sensor. Releasing the spring, the sensor will be set in this installation position.
- After finishing installing, the sensor could be connected to the power and tested.
- When you switch on the power, the light will be on at once. And 10sec±3sec later the light will be off automatically. Then if the sensor receives induction signal again, it can work normally.
- When the sensor receives the second induction signals within the first induction, it will restart to time from the moment.
- Turn LUX knob anti-clockwise on the minimum (3). If the ambient light is less than 3LUX (darkness), the inductor load could work when it receives induction signal.
- Note: When testing in daylight, please turn LUX knob to ☀ (SUN) position, otherwise the sensor could not work!
Notes
- Electrician or experienced human can install it.
- Can not be installed on the uneven and shaky surface
- In front of the sensor there shouldn’t be obstructive object affecting detection
- Avoid installing it near the metal and glass which may affect the sensor.
- For your safety, please don’t open the case if you find hitch after installation.
- After finishing installing, the sensor could be connected to the power and tested.
- When you switch on the power, the light will be on at once. And 10sec±3sec later the light will be off automatically. Then if the sensor receives induction signal again, it can work normally.
- When the sensor receives the second induction signals within the first induction, it will restart to time from the moment.
- Turn LUX knob anti-clockwise on the minimum (3). If the ambient light is less than 3LUX (darkness), the inductor load could work when it receives induction signal.
- Note: When testing in daylight, please turn LUX knob to ☀ (SUN) position, otherwise the sensor could not work!
Some Problems And Solved Way
The load don’t work:
- Check the power and the load
- Whether the indicator light is turned on after sensing? If yes, please check load.
- If the indicator light does not turn on after sensing, please check if the working light corresponds to the ambient light.
- Please check if the working voltage corresponds to the power source.
The sensitivity is poor:
- Please check the ambient temperature.
- Please check if the signal source is in the detection fields.
- Please check the installation height.
The sensor can’t shut automatically the load:
- If there are continual signals in the detection fields.
- If the time delay is set to the longest.
- If the power corresponds to the instruction.
Test
- Turn the LUX knob clockwise on the maximum (sun).
- Turn the SENS knob clockwise on the maximum (+).
- Turn the TIME knob anti-clockwise on the minimum (10s).
