Sell Arduino RCWL-0516 Microwave Radar Induction / Motion Detector Module best price

@Package Includes 1x Arduino RCWL-0516 Microwave Radar Induction / Motion Detector Module @Overview RCWL-0516 is a doppler radar microwave motion sensor module which can act as an alternative to a PIR motion sensor. This git repository is an attempt to collect the rather scant information on this board in one place. Adjustment Part Introduction: 1.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 2.R-GN Detection distance adjustment;connect with resistor and detection distance will become shorter;if not connect,detection distance is 7m;if connect with 1M ohm resistor,detection distance is 5m 3.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 detection function at night @Features Working voltage: 4.0-28.0V 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 @Pinout 1.3V3: 3V3 power output 2.GND: Ground 3.OUT: Control output;when detect moving objects,it will output high level 4.VIN: Input voltage,4-28V 5.CDS: Enable control chip,lower than 0.7V,OUT will output low level all the time
