AC Voltage Sensor 250V

This module is an active single phase voltage sensor module for Arduino, which is based on the high precision ZMPT101B voltage transformer. This module easily monitors the AC mains voltage up to 250 volts, so it can be widely used in industrial and home equipment to sense, measure, and protect equipment against over voltage damage, under voltage damage, and so on. This module has a multi-turn trim pot which can be used for adjusting the analog output.


By using the voltage sensor you can easily measure main voltage using Arduino or even Raspberry Pi (external ADC required). Another benefit of this sensor is that you can adjust analog output corresponding quantity. It is lightweight with an on-board micro-precision voltage transformer which is high precision on-board op-amp circuit, too. In operational amplifier circuit manner, it provides high precision on-board amplifier circuit, the signal to do the exact sampling and adequate compensation and other functions.

By adjusting the potentiometer, the amplitude of the output waveform can be changed (the adjustment process does not change the half value). The waveform changes in the range of 0-VCC. In the process of increasing the amplitude if the distortion of the waveform occurs, it can be solved by suitably increasing VCC operating voltage. If the median value of the waveform is shifted to 0, a capacitor of about 105 pF can be connected in series to the OUT terminal to filter the CONTINUOUS component in the waveform.
