ماژول سنسور تشخيص حرکت مايکروويو RCWL- 0516 داراي زاويه تشخيص 360 درجه. عملکرد اين سنسور مشابه ماژول هاي PIR که کاربرد فراواني در چراغ هاي راه پله و... دارد. همچنين اين ماژول حرکت جسم را در رنج تشخيص خود تشخيص ميدهد. ولي بجاي استفاده از مادون قرمز و گرماي بدن اين سنسور از اثر دوپلر استفاده ميکند. اين ماژول تا رنج 7 متر را تشخيص ميدهد ويژگي ها : ولتاژ ورودي :4 تا 28 ولت مصرف جريان : 2.8 ميلي امپر رنج تشخيص : 5 تا 9 متر

This sensor module has been designed as an alternative to the common PIR motion sensors widely used in burglar alarms and security lights. Like the PIR sensor, this sensor also detects only movements within its detection range. But instead of sniffing the black body radiation from a moving person, this sensor 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. Features: Operating Voltage: 4-28V Operating Current: 2.8mA (typical); 3mA (max) Detection Distance: 5-9m Transmitting Power: 20mW (typical); 30mW (max) Output Voltage: 3.2-3.4V Output Voltage Driving Capacity: 100mA Trigger Way: repeat trigger Output Control Low Level: 0V Output Control High Level: 3.3V Operating Temperature: -20~80 celsius Storage Temperature: -40~100 celsius Board Size: 35.9 X 17.3mm
