New magnetometer with TMR (tunnel magnetoresistance) technology

Recently Bosch Sensortec launched a new magnetic sensors with a very interesting technology, called TMR. It stands for tunnel magnetoresistance. The sensor has the part name BMM350 and is using TMR (tunnel magnetoresistance) technology. This power-efficient sensor technology is using the tunneling effect. This happens in a magnetic tunnel junction (MTJ), which is a component…

SEVERE WEATHER CHANGE MEASUREMENT

Did you know that a barometric pressure sensor can detect severe weather changes and even a huge vulcano eruption several thousands miles away? Weather forecast I think that almost all people have experience with weather stations, these small boxes at home to measure the weather changes. They are relatively precise to predict the weather based…
