Want to sense air temperature? There’s a sensor for that. Particulate content in the air? There’s a sensor for that, too. Someone sneaking up on you? Get yourself some passive infrared sensors ...

Using a sense resistor is only the first step in the current-sensing decision. The other part is topology: whether to use ...

If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer. But the advent of the Hall-effect sensor has provided us ...

Allegro’s CT4022/32 TMR current sensors claim ultra-low noise and high-precision current measurements for clean energy ...

Allegro MicroSystems today announced three ICs: two analogue current sensors and a motor driver for fans. The first current sensor, ACS37630, is designed to be sat on top of a bus bar and partly ...

LEM has announced the addition of two new members to its IN family of current sensors that are suitable for a range of demanding systems in the medical, test and measurement, energy metering and power ...

In an advance in microsensor technology, researchers have unveiled an ultra-sensitive gas detection method using surface ...

The next step is for the sensor to start being used in practical environments. Even if it does work, however, the current influenza outbreak is likely too widespread for it to make a difference.

These new solutions, the ACS37035 and ACS37630 current sensors, and the A89347 automotive-grade fan driver IC, provide advanced capabilities for a wide range of applications. “Our latest motor ...
