It outputs an analog voltage proportional to the measured current, making it easy to interface with microcontrollers like Arduino or ESP32 for power monitoring, energy auditing, or motor control feedback systems. With built-in isolation, it provides a safe and non-invasive way to track current without direct contact.\u003c\/p\u003e\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Range\u003c\/td\u003e\n\u003ctd\u003e0 to 5A AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eAnalog Voltage (0–1V RMS proportional)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensitivity\u003c\/td\u003e\n\u003ctd\u003e185 mV\/A (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Range\u003c\/td\u003e\n\u003ctd\u003e50Hz \/ 60Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e±1% (at rated current)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/smart-energy-monitor-kit-build-a-classroom-power-logger-with-arduino\"\u003eDIY home energy monitor to track appliance power consumption.\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eOvercurrent protection circuit for motors or power supplies.\u003c\/li\u003e\n\u003cli\u003eSmart irrigation system with pump current sensing.\u003c\/li\u003e\n\u003cli\u003eReal-time electricity usage logger with IoT dashboard.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis module works with any microcontroller that has an analog-to-digital converter (ADC), such as Arduino Uno, Nano, ESP8266, ESP32, or Raspberry Pi Pico. It requires a 5V supply and outputs a voltage within 0–1V RMS, which can be read directly via ADC; for 3.3V systems, a level shifter may be needed. Commonly paired with relay modules for full control and monitoring of AC loads.\u003c\/p\u003e\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect the sensor’s VCC to 5V, GND to ground, and the analog output (OUT) to an ADC pin. Since the output is AC, you’ll need to sample it rapidly and calculate RMS in software; no external pull-ups are required. Ensure the measured current does not exceed 5A to avoid saturation.\u003c\/p\u003e\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
