High accuracy at a low cost over a wide temperature range makes thermal MEMS accelerometers the hot choice in tilt sensing. Find out whether they're right for your application.

The development of "active," noncontact sensors based on Hall effect, magnetoresistive, and variable-reluctance transformer technologies is penetrating the established market of "passive," contact sensors—and increasingly taking market share for automotive speed and position applications, says market research firm Strategy Analytics. "This is being driven by the need for improved reliability as well as increased functionality and accuracy," notes senior analyst Simon Schofield.
