RCWL-0516 Microwave Radar Sensor Module Human Body Switch Induction Module Back side with Onboard Regulated 3.3V supply

Description

The RCWL-0516 is a small proximity sensor that uses Dopler Radar to sense the presence of an intruder. It is very versatile and can be used on its own or in conjunction with a microcontroller or microcomputer.
This device does not consume much current and operates in a range of 4 to 28 volts, making it an ideal component for a battery-powered design.
The microwave antennas are integrated onto the small printed circuit board, making it a completely self-contained unit.
The RCWL-0516 also support an optional light-dependent resistor (LDR) to allow the device to operate only in darkness. This can be very useful in light control applications.
The RCWL-0516 employs “Doppler Radar” to detect movement and thus trigger a proximity alert.
The device has an integrated 3.3 volt voltage regulator which can provide up to 100 mA of current for powering external logic circuitry.
