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 Òmicrowave Doppler radarÓ 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.

Pinouts:

• CDS Ð Sensor disable input (low = disable)
• VIN Ð 4- to 28-V DC supply input
• OUT Ð HIGH (3.3 V) motion detected/LOW (0 V) idle
• GND Ð Ground/0 V
• 3V3 Ð Regulated DC output (100 mA max)

Features:

• Transmission signal processing control chip RCWL-9196
• Wide operating voltage range: 4.0-28.0V
• Compared with the traditional infrared feeling PIR, with the penetrating detection capability
• Block time, distance adjustable
• Output 3.3V power supply

Package Includes:

• 1 x RCWL-0516 Microwave Radar Sensor
