[Trax] was asked by a friend to build a device that could detect the presence of a car in front of his garage gate for it to open automatically. After searching the web for such a project and trying ...

The DRV421 magnetic-sensing IC from Texas Instruments integrates a fluxgate sensor and compensation coil driver, along with all the required signal-conditioning circuitry, in a 4×4-mm WQFN PowerPad ...

Inductive loop detectors were introduced in the early 1960s and have been one of the most widely used sensors for traffic management on freeways, arterials, and intersections. These sensors are used ...

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 ...

Industrial temperature sensors are widely used with 4–20mA current-loop transmitters in industrial control and automation. In the current loop the temperature sensor converts a temperature into a ...
