## Description

desertcart.com : MENGQI-CONTROL Request to Exit PIR Motion Sensor Exit Infrared Detector for Exit for Automatic Opening Door Access Control : Electronics

Review: Great inexpensive sensor - Easy to install, easy to adjust and works great for our purposes. Simple wiring made it easy and has been working fine for 6 months now, seems good build quality with not much issues. Time will tell, but so far so good.
Review: Good Product - I originally got these as part of a package and didn't know what to expect. Turns out the are really good motion sensors and have purchaed many more sice then. I really cant find anything wrong with them and have had several in place for over 3 years without a single problem. The abfle and sesitivity can be adjusted and with a little tweaking (depending on what you're them for) you can delay the motion sensing within 2-3 feet of sensor. GEt one before they are gone.

### ⭐⭐⭐⭐⭐ Microwave Radar sensor
*by S***R on June 19, 2020*

This microwave radar detector works fine. I used it to replace my PIR sensor because the PIR sensor falsed a lot during daytime. The product data specs are for 60VAC switching voltage, but I need to switch 110VAC. The relay is marked for that, but to be safe I used its NO ("Normally Open") relay to run another relay. The listing as of now says it is a PIR (Passive InfraRed) sensor, it is NOT, it is a microwave doppler radar sensor. I find it much more reliable than PIR sensor in daytime, but the area I'm covering with it doesn't have trees, etc. that blow in the wind that could disturb it. With sensitivity set to maximum, about nine foot mounting height, and appropriate sensor position adjustment it covers a semicircle with about 20 foot radius. Similar units are EE124GMW and M-204G.
