I've bought ph-meter PH-4502C and now want to connect it with Wemos D1 mini.
There is analog output (as I understand Po). Powersupply for PH is 5V, with verification liquid it has on Po-pin 3,92V (more than 3V). So, but in Wemos specification is that on Analog input must be not more than 3v. How to make correct transformation? is it enough to use resistor and what value?
