Magnetometers and MEMS
Magnetometers One of the earliest sensors that humans made to aid us as we navigated the world, was the compass. Long before the accelerometer, the gieger counter, or the frog leg oscilloscope, nearly one thousand years ago inventors in China noticed that a lodestone (a natural magnet) would align itself in a consistent direction if…

Resisting the Heat
Resistance-Temperature Sensors, RTDs and Thermistors I was at an event recently and one of the topics was sensor basics, brilliant, right in my wheelhouse. The presenter started a section on thermo-couples by discussing the range of sensor types available and listed both RTDs (Resistance Temperature Detectors) and Thermistors (Thermal-resistors) as competing sensor types to Thermo-couples…
