## Overview

The 5PCS RCWL-0516 Microwave Radar Sensor Modules offer advanced motion detection with a 5-7 meter range, penetrating walls and obstacles. Designed for makers and professionals, these modules support a broad 4-28V power range and are fully compatible with popular microcontrollers like Arduino and ESP8266. Adjustable sensitivity and timing features empower precise customization, making them ideal for innovative security, automation, and animal detection projects.

## Description

Description: Wide operating voltage range: 4-28V Can output 3.3V power supply Blocking time, adjustable distance Using special signal processing control chip RCWL-9196 Compared with the traditional infrared induction PIR, the penetration detection ability About pin header: CDS = No connection VIN = 5vdc (+) (9v battery also Ok) OUT = 3.3vdc signal out when triggered GND = 0vdc (-) 3V3 = No connection (in most applications) C-TM: Adjust repeat trigger time (default 2 s). Adding a capacitor will give a longer repeat trigger time. R-GN: Detection distance is adjustable (default 7 m). Adding a resistor the detection distance will become shorter. If connected with a 1-MΩ resistor, detection range is about 5 m. R-CDS: By adding a resistor (in parallel with the internal 1-MΩ resistor), user can change the light detection threshold as per individual requirement. This is applicable only when a light sensor is soldered in its pads (CDS) on the front of the circuit board. A 47–100K resistor works fine with standard 5-mm LDRs Package Included: 5 X RCWL-0516 Microwave Radar Sensor Module 5 X 4P Bend Pin Headers FAQ: Q: Can you use the RCWL-0516 with an ESP8266? Or will you get random false positive results? A: I've done a short term test with the ESP8266 on a NodeMCU board. It seems to work just fine. The ESP greater Version 12-E is shielded and is FCC certified. So it should, by definition, not interfere with other electronics. However, one viewer reported random false positive results on a long shot. Q: Is the water in the human body responsible for the detection? A: Probably. I tested it with one empty and one water filled bottle. And even with a cat. And it seems that the bigger the object the further away it can be detected.

Review: This is for the microwave sensor, not the PIR. Confusing to have two separate products in one listing.... Anyway, the sensor works great. It seems to work only when at 5v, not the 3.3. At least in my experience. Just a word of warning, this thing is pretty much omnidirectional. It senses through walls and through floors. It's not entirely what I wanted, but I can't give it a bad review as it does what it's supposed to do, I just wasn't aware of it. Anyway, as an in-room motion detector it kidna sucks, as it will detect other rooms. Unless you have a Faraday cage I guess. I suppose it could be useful if you just want to know if someone is at home. In a flat, that's not so much use as it detects downstairs moving, as well as pigeons on the roof...
Review: El producto cumple su función aunque es muy sensible (>4m de distancia probado) y casi omnidireccional por lo que para un uso dirigido hay que diseñar una guía de ondas. En mi caso particular hubiera preferido que el header de contactos viniera soldado pero tampoco es imprescindible.

## 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. Tutorials contact us.
- 🚩 It can work with (for) ar duino/nodemcu/wemos etc.; It can detect human, cat, rat, water. Works with Ar duino and Nodemcu Document link, please contact us.

*by X***N on 10 November 2019*

The sensor is worked from the very first time with Arduino Uno WiFi Rev2. 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.
