Recently, I’ve been working on a solar off-grid monitoring system. In the system are a few split-core Hall effect sensors to monitor DC current in the solar panel current, the battery charge current, ...

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 ...

Use of 4-to-20-mA current loops involves more than just a simple series connection between sensor, display, and power supply. The point where a sensor takes a measurement is, at times, many yards away ...

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 ...

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...

LEM is aiming at electric vehicle state-of-charge estimation with a ±1.5kA current sensor. To be called the SMU series and designed to be built into the ‘battery disconnect unit’, the sensors “reach 1 ...

Current sensing has long been an important function implemented by battery management systems (BMS), modules which monitor and protect high-capacity batteries. In both lithium-ion and sealed lead-acid ...

Melexis has introduced a linear Hall sensor for use as a current sensor. With its fast response time and improved stability over operating temperature and over lifetime, the MLX91209CA is optimized ...
