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 ...

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 ...

In various industries and applications, it’s crucial to monitor the current and frequency of devices in real-time. These ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

Texas instruments has introduced a precision bi-directional current sense amplifier than can measure voltage drops across shunt resistors over a common-mode range of -5 to 110V, with survival across ...

ABB has launched its latest generation Fiber Optic Current Sensor (FOCS-FS) to complement its portfolio of optical sensors. The FOCS-FS gets its name from its ‘free standing’ design. A salient feature ...

Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of ...
