Does anybody know how to configure my Ads1115 node which is conected to zmpt101b converter (with this I convert voltage 220V) to read corectly the values of voltage (220V)?
I used a debug node and it gave me random values like 1.12, 1.55, 1.70, 2.1 V then these values decrease (like they convert a values of a sinus which increase and Decrease). I don't know to interpret them.
Ads1115 is conected to 3,3 V (Vin) . Without connecting Zmpt101b converter IT gave me a fix value of a half of Vin(1.61V). After I connect on A0 input the Zmpt101b converter, The values are going to oscillate, like they follow a sinus.
Thank you in advance!
