Introduction
The voltage sensor module is a resistive voltage divider circuit-based DC voltage sensing device. It creates a corresponding analog output by reducing the input voltage signal. Below we are discussing ZMPT101B AC Single Phase Voltage Sensor Module.
AC Single Phase Voltage Sensor Module
ZMPT101B is a basic but highly useful module that reduces an input voltage by a factor of 5 using a potential divider. The 0-25V Voltage Sensor Module allows you to use a microcontroller’s analog input to monitor voltages far higher than it can sense. Thus, it is ideal for use in DIY projects requiring precise AC voltage measurement via a voltage transformer. With this module, you can measure Voltage levels up to 250 volts. This sensor’s output is analog. When we change the input voltage, the output voltage changes as well.
