Perfect for Arduino Projects
Used this to monitor mains voltage in my home automation setup. The output is stable and reads accurately on the ADC pin.
Q: Is the output linear?
A: Yes, the output voltage is proportional to input voltage within the rated range.
Q: How do I connect to ESP32?
A: Connect output to ADC pin and GND to common ground. Ensure voltage levels match ADC limits.
Q: What is the max input voltage?
A: This module supports up to 250V AC input safely within specified limits.
Q: Does it require external power?
A: No, it is passive on the input side, output drives the sensor directly from the input signal.
Q: Can I use this for DC voltage?
A: No, this is designed specifically for AC voltage sensing and will not work with DC.
