Blue 3.5mm 20A/1V SCT013-020 AC Current Sensor Module Split Core Current Transformer
Description:
This module has been designed as an alternative to the PIR motion detectors commonly used in burglar alarms. Instead of sensing changes in infrared radio emitted by a moving person this sensor uses a microwave Doppler radar to detect moving objects. It has a sensitivity range of ~7 meters. When triggered its trigger output pin will switch from (LOW) 0V to high (3.3V) for ~ 2 to 3 seconds before returning to its idle LOW state.
Specification:
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
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
Pin Definition:
3V3:3V3 power output
GND:ground
OUT:control output;when detect 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:
1 pc RCWL-0516 Switch Module
