RCWL-0516 Microwave RADAR Sensor

Like the traditional PIR sensor, RCWL-0516 is a widely popular sensor that also detects movements and is used in Alarms or for security purposes.

• This sensor uses a “ microwave Doppler radar ” technique to detect moving objects within its range.
• It has a sensitivity range of ~7 meters and that is very useful for multiple applications.
• When triggered, its TTL-level output pin changes state from LOW which is 0V to HIGH which is 3.3 V.
• The changed HIGH state remains HIGH for 2 to 3s which is a proper time to trigger something.
• As this sensor module provides output for 3.3V, it can easily be interfaced in with many microcontrollers and even can be used without a microcontroller.
• It has a power supply input range from 4 to 28 V.
• RCWL-0516 pinout: Specification: - Operating Voltage (VDC) : 4 ~ 28V Max.
• Operating Current (mA): 3 Detecting Range : 5-9m Transmitting Power  : 20mW (typical); 30mW (max) Output Voltage(V)     : 3.2 ~ 3.4 Output Voltage Driving Capacity : 100mA Trigger Way   : Repeat Trigger Output Control Low Level   : 0V Output Control High Level   : 3.3V Operating Temperature (°C)            : -20 to 80 Adjustable Block time and distance Penetrating detection capability, compared with the traditional infrared feeling PIR.
• RCWL-0516 Dimension and footprint: Application: Security Motion and Movement Detection Alarm System Indoor Tracking System Package Contains 1x RCWL-0516 RADAR Sensor Module.
