Description of ๐Ÿ”ฌ J LUMI YCA2002 Microwave Doppler Sensor

| MODERN DESIGN | This next generation motion detector has a clean and modern profile with a classic UFO shape. The body housing is made with premium polycarbonate material stronger than ABS plastic and gives a beautiful smooth finish. Standard white low profile allows this sensor to blend seamlessly into your ceiling. | MICROWAVE RADAR | Our microwave sensor emits microwave signals to detect moving object, the same way a radar speed detector works. It is more accurate and consistently outperforms a PIR motion sensor, which tends to be less sensitive in high temperature and over sensitive in low temperature. | FULL DETECTION CAPABILITY | Features 360-degree detection with 30-ft diameter detection range. Radar waves are capable of penetrating glass, paper, plastic and thin walls. Compared with a PIR motion sensor, a radar motion detector is less likely to be limited by place of installation, and could detect objects before they see the sensor. | PHOTOCELL ENABLED | With built in photocell operated by switch for daylight (24/7 mode) or night mode (only trigger after dark), making the sensor a perfect replacement of PIR sensors. | SAFE TO USE | This sensor emits microwave power at 10 milliwatt, which is 1/100 of a normal cell phone (typically 1-2 watts of power). Suggested install height is 8-12 ft. compared to a cellphone which is normally used within 3 ft. You can use this radar motion detector safely and with peace of mind. Please review wiring diagram to make sure wiring is done correctly.

Fine if your application allows it

Recognizes people well, but not rats. Strange assembly. Not suitable for a standard bell, but comes with screws for flush mounting to a ceiling or wall. However, the wires exit from the back, not the side. Definitely no code. Also note that it detects through walls and connects to a Wi-Fi device if it gets too close.

Pros
  • Robust surface
Cons
  • There are flaws

Works great - as advertised

Fast shipping, easy install, works great. I'm not an electrician, but I can change a switch or socket. The instructions were easy to follow. The first one worked so well in the garage that I put another one in my shop. Also added a J.LUMI PIR sensor on the porch for fans. Great products and business support.

Pros
  • Confident
Cons
  • Some bugs

Works well where PIR doesn't work.

I bought this to replace a very expensive PIR device but the nearby air conditioner vent was often causing false alarms. This device solved that problem. The only "problem" I had with this unit is that the unit is designed for a 3 inch box while my setup is a 4 inch box. This was a simple fix, first attaching it to the 4" round cap and then assembling the cap sensor assembly.

Pros
  • Robust design
Cons
  • The list will be long.

Fastening system

This unit works as expected but the designer needs to make changes! They send plastic anchors with screws, and the instructions suggest attaching them to the ceiling by running electrical wires through the ceiling. All devices, with the exception of low-voltage devices, must be connected to a socket or device socket! This company (Chinese) must use metric measurements as none of their equipment I use properly fits the standard mounting holes of our electrical boxes or plaster rings.

Pros
  • Nice packaging
Cons
  • Can't remember

Disappointed

I really thought this would replace my existing motion sensor in my dressing room and that I would get improved performance due to the technology difference; However, there were a few things I didn't like. There were no instructions. I had to extract all of the installation information that I used from the photos that accompany the Revain listing for this product.2. This will not fit the standard round hole. It's a bit smaller so I need to make an adapter with the blank ceiling mount cover.3โ€ฆ

Pros
  • Price
Cons
  • Minor issues

Revainrating 1 out of 5

False alarms, freezes, wifi glitches and unreliable connections

I really wanted to like this sensor. It was nice that it detects a door opening and turns on the light when you walk in, as opposed to an IR sensor that has to see the body before it turns off. However, there are a couple of interruption issues that forced me to bring them back. Difficult to set up and get stuck: The main problem is that they are buggy and cannot be set up properly. After two days of trying to set them up I can't help them get stuck. They are set to the lowest time setting (8โ€ฆ

Pros
  • Few competitors
Cons
  • unreliable
