RCWL-0516 Microwave Radar Sensor Induction Switch Sensor Module

Description:

RCWL-0516 Microwave Radar Sensor module designed as an alternative to the common PIR motion sensors widely used in burglar alarms and security lights. Detects only movements within its detection range.
Uses a “microwave Doppler radar” technique to detect moving objects. It has a sensitivity range of ~7 meters. When triggered, its TTL-level output (OUT) pin will switch from LOW (0 V) to HIGH (3.3 V) for a finite time (2 to 3 s) before returning to its idle (LOW) state.This flexible sensor module can easily be used in conjunction with many microcontrollers and even without a microcontroller at all. It can handle power supply inputs anywhere from 4 to 28 V.

Features :
- Transmission signal processing control chip RCWL-9196
-  Wide operating voltage range 4.0V to 28.0V
-  Penetrating detection capability, compared with the traditional infrared feeling PIR
-  Adjustable Block time and distance
-  Operating Current: 2.8mA (typical); 3mA (max)
- Detection Distance: 5-9m
- Transmitting Power: 20mW (typical); 30mW (max)
- 3.3V output power supply
- Operating frequency: ~3.2 GHz (observed by me at my lab)
