RCWL-0516 Microwave Radar Sensor
- Product SKU: R0164
- Category: Arduino Ecosystem, Beginner Friendly, ESP32 & NodeMCU Ecosystem, Sensor Only (Without Module), Sensors, Sensors, Under ₹100
The RCWL-0516 Microwave Radar Sensor module offers an alternative to traditional PIR motion sensors commonly used in security systems and lighting. Unlike PIR sensors, which detect infrared radiation from moving objects, this module uses microwave Doppler radar to sense movement within its range.
The sensor has a detection range of approximately 7 meters. When movement is detected, the TTL-level output (OUT) pin switches from LOW (0 V) to HIGH (3.3 V) for about 2 to 3 seconds before returning to its idle LOW state.
This versatile sensor module can be integrated with various microcontrollers or used independently. It supports power supply inputs ranging from 4 to 28 V.
The output pin can be used for various applications, such as activating alarms or visual indicators, or interfacing with the I/O of a 3-V microcontroller for additional processing. For optimal performance, avoid placing any metal objects in front.
