15pcs RCWL-0516 4-28V 3mA Microwave Radar Sensor Human Body Induction Switch Module Board Smart Induction Prober

Features: Size: approx. 1.7 x 3.5cm / 0.67 x 1.38" Operating voltage: 4 - 28V Operating current: 2.8mA (typical) 3mA (max) Probe distance: 5-9m Transmitting power: 20mW (typical) 30mW (max) Output voltage: 3.2 - 3.4V Output voltage driving capacity: 100mA Output control low level: 0V Output control high level: 3.3V Operating temperature: -20 - 80 Storage temperature: -40 - 100 Trigger way: repeat trigger Adjustable distance, high sensitivity, the module has a far sensing distance, reliable, large induction angle and has a wide supply voltage range Widely used in a variety of human induction lighting and burglar alarm and so on. Adjustment part introduction: C-TM: Adjust repeat trigger time, default trigger time is 2s; increasing capacitor's capacity will make repeat trigger time longer; and actual counting trigger time can operate as below: Stick capacitor on C-TM, test 9196 3-pin frequency F, repeat trigger time T=(1/f)*32768. R-GN: Probe distance adjustment;connect with resistor and probe distance will become shorter; if not connect, probe distance is 7m; if connect with 1M ohm resistor, probe distance is 5m. R-CDS: Internal VCC parallel connect with internal 1M ohm resistor to CDS pin (that is 196 9-pin) by R-CDS, CDS connects with photoresistor, you can close probe function at night. Pin definition: 3V3: 3V3 power output GND: ground OUT: control output; when probe moving objects, it will output high level VIN: input voltage, 4-28V CDS: enable control chip, lower than 0.7V, OUT will output low level all the time Package included: 15 x RCWL-0516 sensor module
