Quick Sense(QS-M5B) Plastic 360 Degree Sq Type Microwave Motion Sensor with Light Sensor (White)(Pack of 1) (QS-M3)

Nice product, I install it for exaust fan & it's working perfectly.

Good ok

Installed this product in our building apartment complex to save on electricity costs. It performs beautifully. Sensing is very precise and can detect motion from behind wooden doors too. Thus people are not inconvenienced when they open the doors at night. The lights will get switched on. The light sensor is very good and the lumens can be set so that the lights do not get switched on in daytime.

Its is extremely disaster device, sometimes it dose not turn off the lights, sometimes it starts fluctuating the light and it is even not working with inverter power supply. I replace the product twice but same result. I don’t know how they are selling these faulty product on Amazon.

Quick Sense(QS-M5B) motion sensor module is a game-changer! The installation was a breeze, and the sensor is highly responsive to even the slightest movement. It seamlessly turns on the light whenever someone enters the room and turns off shortly after they leave. This not only enhances convenience but also helps save energy. The range of the sensor is impressive, covering a wide area effectively. The build quality is sturdy, ensuring durability in the long run. Overall, I am extremely satisfied with the performance of this motion sensor module. It has made my life easier and my home more energy-efficient with only a consumption of just 0.9W!!!. Highly recommended for anyone looking to upgrade their lighting system!

Product is good, as long as its working fine. Very difficult to get help/ support from post warranty from the OEM. They keep sending forms to fill in but for no avail. Consider it as a disposable product since cant get repairs post warranty.

I am using this device from last 15 days. Here are pros and consPro. 1. It can detect through window panes and small plastic plates.2. It has detection radius of 8 meter not 10 meter.Response time is 2 secs.3. Really saves electricity.4. The Lumix timer works well.Cons: 1. Not Water proof, you have to figure out the solution if.you are keeping it outside.2. Photovoltaic sensor (which switch off lights during daytime) sometimes, doesn't work well- may be due to ia hve received faulty product.3. Cannot permiate through 9" concrete walls.I Havenot tested on 4" concrete walls4. Tick tick noise can be listened to while load switch on during operation. - we can extempt this because this noise is not that too much.Overall 4.5 starUpdate after 11 months of experienceStill working goodI have added a small plastic box to hide it from rainNo problem till dateImage attached

It's almost a month now. Love this product. Motion detection is accurate and very easy to install.
