VAC Current Sensing Module 0-5A CT Sensor



The board combines by three parts, VAC current sensor, attiny 1604 controller core (arduino supported) and relay drive output.

VAC current CT sensor specifications:

  • VAC current range 0-5A load
  • Sensing precisions 0.01A (10mA)

ATtiny1604 microcontroller:

  • Lead out all pins of the chip on board
  • Simple and easy way to flash the code by UPDI prototol
  • Direct support OLED I2C
  • Pin Definitions:
    • Three analog value buttons on pin PA1
    • CT sensor input pin PA2
    • Input VDC power supply read on pin PA3
    • Relay control output on pin PA4
    • On board programmable LED output on pin PA5

Other Board Features:

  • On board 10A VAC control relay, for capacitive load like motors should be within 3A VAC
  • On board VDC power supply in up to 40V 3A, provide on board power around 4.8V
  • On board three analog input buttons

Shipment not includes the OLED, please buy or prepare by yourself.
