Very simple to use and detects motion well. We got it for school science project and had no trouble with getting it to work. You do need to solder the pins on the board but that is very clear from the description. The only downside is that my package came with 4 pin strips instead of 5 pin as shown in the picture. For the correct operation you only need 3 pins so that is not a problem. I just used my own pins but the included should also work just fine. There are number of examples online on how to use this sensor with Arduino. Over all the sensor is very good and the price is reasonable. I would recommend this over the PIR sensors, as I had better success with this sensor. Review: Very tricky to use. - An official guide to using these would be useful. After much experimenting I found that the likely reason they suggest you put this on the end of a cable 12" to 18" long is two fold. Firstly, you are supposed to leave 1cm of clear space around it. Presumably that's linked to the wavelength of the radar. If you mount it directly on a breadboard it has detection range less than 3cm. Secondly, if it's too close to other electronics, they can set it off. I had an ESP8266 WiFi module close it it, which set it of when the ESP came out of sleep mode. I tried placing it in bedroom and got false positives because it was sitting close to a WiFi router. If you know all of this then it's a very useful device and detects things very well. I ended up having to wake up the WiFi and ignore all the false positives coming from this device until the WiFi was back in sleep mode. ## Features - 🚩 This RCWL-0516 module has the characteristics of high sensitivity, high induction distance, high reliability, large induction angle, wide power supply voltage range, etc. it is widely used in various kinds of human body induction lighting and alarm and so on. - 🚩 The RCWL-0516 microwave radar sensor module can detect inert object at the condition that it has enough density, volume and it is in motion. - 🚩 Microwave radar sensor will sense motion through most anything. The more shielding there is, the less detection range you get. I can detect motion through glass, drywall walls, ceilings and floors. It is very sensitive. You might have to filter the power supply. - 🚩 This microwave detector board can not only detect human but animals and water. - 🚩 Microwave doppler radar sensor can work with arduino/nodemcu/wemos etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07MTWZDQZ | | Best Sellers Rank | #504 in Motion Detectors (Electronics) | | Brand | Stemedu | | Brand Name | Stemedu | | Customer Reviews | 4.0 out of 5 stars 185 Reviews | | Item Weight | 0.63 Ounces | | Manufacturer | Stemedu | | Material | Semiconductor, Metal, Plastic | | Material Type | Semiconductor, Metal, Plastic | | Maximum Supply Voltage | 28 Volts (DC) | | Model | ST | | Mounting Type | Weaver Mount | | Output Type | Digital Signal | | Response Time | 2 seconds | | Sensing Distance | 7 Meters | | Specific Uses For Product | motion detection, security systems, automatic lighting, animal monitoring | | Style | Modern | | Style Name | Modern | | UPC | 747356634496 747356633208 747356634816 | ## Product Details - **Brand:** Stemedu - **Item Weight:** 0.63 Ounces - **Style:** Modern - **Maximum Supply Voltage:** 28 Volts (DC) - **Mounting Type:** Weaver Mount ## Images ![5PCS RCWL-0516 Motion Detection Sensor, Microwave Radar Sensor Switch Module for Arduino ESP8266 Nodemcu Wemos for Animals Detector, Detection Distance 5-7m, Better Than HC-SR501 - Image 1](https://m.media-amazon.com/images/I/61gsva15LQL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked with Arduino WiFi Rev2 *by X***N on November 10, 2019* The sensor is worked from the very first time with Arduino Uno WiFi Rev2.

Thus, there's ~1/4" of wood plus the pvc in front of the sensor, and 3 1/2" of wood plus the pvc behind it. It senses people or cars at up to ~15 feet in front, and totally ignores any movement behind, which is perfect for my use. When used indoors, the sensor is just too sensitive, and can be tamed if you're skilled with a soldering iron, by attaching a 1MegOhm resistor between points R and GN on the board. When used outdoors, with the added resistor, the sensor essentially does nothing, but works perfectly as described above, without the resistor. I've thus far tested 4 of the 5 received, and they've all worked. ## Frequently Bought Together - Stemedu 5PCS RCWL-0516 Motion Detection Sensor, Microwave Radar Sensor Switch Module for Arduino ESP8266 Nodemcu Wemos for Animals Detector, Detection Distance 5-7m, Better Than HC-SR501 - CQRobot 10.525GHz Doppler Effect Microwave Motion Sensor Compatible with Raspberry Pi and Arduino Motherboard. for Industrial, Measurement, Automatic Doors, Smart Lights, Reversing Radar, etc. - HiLetgo 3pcs HC-SR501 PIR Infrared Sensor Human Body Infrared Motion Module for Arduino Raspberry Pi --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/107629102-5pcs-rcwl-0516-motion-detection-sensor-microwave-radar-sensor-switch](https://www.desertcart.pl/products/107629102-5pcs-rcwl-0516-motion-detection-sensor-microwave-radar-sensor-switch) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-22*
