Review on 🔎 Stemedu 5PCS RCWL-0516 Motion Detection Sensor: Advanced Microwave Radar Module for Arduino ESP8266 Nodemcu Wemos - Ideal for Animal Detection, Long Range 5-7m, Outperforms HC-SR501 by Kaveen Reyes

Sensor works with Arduino Uno WiFi Rev2 out of the box. Very easy to use and detects movements well. We got it for a school science project and it worked without any problems. You have to solder the pins on the board, but this is very clear from the description. The only downside is that my package had 4 pin headers instead of 5 pins as shown in the picture. They only need 3 pins to work properly so that's not a problem. I only used my own contacts, but the ones provided should work just fine too. There are many examples online of how to use this sensor with an Arduino. In general, the sensor is very good and the price reasonable. I would recommend this instead of PIR sensors as I've had more success with this sensor.
