voltage measurement

I am developing IoT device using ESP32. I am using ESP32 along with ADS1115 for voltage measurement of my equipment. My electrical device operates with following parameter : ~0-5 V DC , 25 Amp with constant current mode adjustment prior to operation. I want to measure this voltage change...

Hey all, I'm using a MAX20480DATEJ/VY+ voltage monitor for my design. Out of four inputs, I prefer to set IN1 2.5V at the same time for testing purposes. When I'm running my command, I'm constantly getting a Fault condition detected message. What can I do to make this work? I have shared the...

My digital multimeter starts fluctuating while I bring it near to my started bike even if the probes are not connected to any where .I can't read any value during that time.Therefore I cannot check my bike electrical circuit.My multimeter shows correct values when I connect to home ac supply...

Hello, Has anyone ever used one of these ZMPT101B current transformers for measuring AC voltage with a microcontroller? I’m struggling to get any linearity with it at all and I can’t understand why. Here is what I’m doing: I’m using a Variac which can produce voltages from 1vac – 330vac If I...
