Easy AC current measurement: This module lets you monitor and measure alternating current conveniently, giving fast access to real-time AC current values for development and testing. Simple integration with MCU boards: Designed to connect directly to MCU development boards via a 3‑pin or 4‑pin interface, so you can add AC current sensing to microcontroller projects with minimal wiring. Adjustable analog output range: The module provides an analog output whose range can be adjusted to match your ADC or data-acquisition input, making it easier to get usable, scaled signals without extra circuitry. Precise and stable readings: Onboard compensation and a high‑gain amplifier improve measurement accuracy and stability, reducing drift and the need for frequent recalibration. Key attributes Function: AC current sensing and analog output for MCU-based systems. Compatibility: Directly interfaces with MCU development boards using 3p/4p connectors. Performance: High-gain onboard amplification plus compensation for reliable, repeatable results. Form factor: Module designed for straightforward mounting and wiring into development setups. Practical use scenarios Prototype power monitoring: Integrate the module into a development board project to measure AC current draw from motors, transformers, or power supplies during design verification. Motor control feedback: Use the analog output to feed current measurements into an MCU ADC for closed-loop motor control, overload detection, or efficiency tuning. Appliance and load testing: Add the module to test rigs to monitor AC current of small household appliances or electronic loads and log the analog signal for analysis. What you gain Faster development: Quick hookup to MCU boards and an adjustable output reduce setup time. Cleaner data: Onboard compensation and amplification deliver more dependable measurements for control and monitoring tasks. Versatile integration: The selectable 3‑pin/4‑pin connection and adjustable output range make it adaptable to many MCU platforms and ADC input ranges.
