This sensor device is built to measure the amount of current being used, especially in power supplies as the design is based on Arduino. The main component used is the ACS712 sensor from Allegro ...

The title says it all – this article describes a microcontroller-compatible current sensor module you can build yourself, using an inexpensive 8-pin chip as an ‘active shunt’ for measuring ac/dc ...

All will work with a 5V MCU on the cool side. A heath warning: Do not mess with the mains if you don’t know what you are doing. In modules, any safety performance that these devices have is often ...
