    Hi, You need to have a code to calibrate the CJMCU AS3939 board to get the right value of capacitance. I would not bother to buy it, there are better board pre calibrated. I could not find any wiring diagram/ arduino code that would work with CJMCU AS3935 sensor board. Spend over 6 months and then I gave up. I suggest you use the same sensor mentioned in this project.

    Hi, in code there is #define SI_PIN 9. if we look at the wiring diagram the pin 9 is not plugged? What I found challenging is the wiring it self.. If I run another program for example I2C Scan, it doesnt find any equipped sensor borad. So could there be somethin wrong wiht the wiring itself?
