AC Current Sensor Analog Current Meter Module 3P 4P Interface for MCU Development Board

AC Current Sensor Module for MCU Projects This analogue current meter module is built around the TA12-100 current transformer and converts AC signals into small-amplitude outputs that are easy for a microcontroller to read. With a maximum input of 5A and an output range of -1V, it is well suited to monitoring and measurement projects where you need to sense alternating current safely and simply. Simple Wiring and Wide Compatibility The module uses a straightforward 3-wire electronic block interface with a 5V input and ground connection, making it easy to link up with your MCU development board. The built-in 3-pin and 4-pin connection interfaces provide flexible options for power and signal output, so you can integrate the sensor into your existing setup without complicated wiring. Accurate Signal Conversion A high-precision amplifier with frequency compensation is built into the module to help maintain measurement accuracy across a range of operating conditions. The TA12-100 transformer reduces AC signals to a manageable level, giving your development board a clean, proportional signal to work with. This makes the module a practical choice for current sensing in hobbyist electronics, educational projects, and prototype development.
