I needed a multichannel line tracker sensor module for an upcoming project. A quick search found several versions of infrared line tracker sensor modules that met or exceeded my demands, but I picked ...

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 ...

When taking measurements from analog sensors located at long distances, voltage drops and noise can affect precision of the readings. Therefore, a voltage-to-current (V/I) module is needed to transmit ...

// and the voltage source frequency is 50 Hz. ZMPT101B voltageSensor(34, 50.0); #define SCREEN_WIDTH 128 // ORelay display width, in pixels #define SCREEN_HEIGHT 64 // ORelay display height, in pixels ...

The ESP32 is the central microcontroller used in the system. It is a powerful, dual-core processor with integrated Wi-Fi and Bluetooth capabilities. The ESP32 enables real-time processing of sensor ...

Abstract: This article presents a self-powered, nonintrusive monitoring (NIM) unit for voltage and current in a typical two-wire electrical system. This article addresses two new aspects of an NIM ...
