Those traffic loop sensors embedded at stop lights to detect the presence of a car have always provided fodder for vehicular snake oil vendors: I’ve seen products promising to eliminate red ...

Simple construction allows an open-loop Hall effect sensor to beat its closed-loop counterparts in terms of price, weight, and size; yet it may be susceptible to temperature variation and saturation.

All the necessary components for a closed-loop circuit, such as compensation coil, Rshunt, and TMR sensor bridge, are integrated into a small 1 mm thin industry standard TSSOP16 SMD package.

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 ...

Current loops aren’t limited to sensors, of course. A wide range of actuators, from valves to motor drives, can be controlled by a 4-20 mA loop. Data acquisition and display are also possible ...

Unlike a simple pedometer that only counts steps taken, the Loop 2 tracks your overall activity, no matter the type. The sensors do a pretty good job at determining when you’re sitting ...
