We tested popular wideband O₂ controllers against lab-grade equipment to see how accurate their lambda readings really are under real engine conditions.

CHICAGO - Test instruments, meters, sensors, and monitors continue to gain sophistication. It’s the way diagnostic tools are headed, based upon what manufacturers brought and introduced at the 2009 ...

The wearable sensor market is growing at an annual compound rate of 17.8%. However, sensors have challenges, particularly in terms of miniaturization and power consumption. Several key parameters are ...

When they need to add temperature control to a project, many hackers reach for a K-type thermocouple for their high-temperature needs, or an integrated temperature-sensing IC when it doesn’t get that ...

Most electronic engineers know that a transistor’s base-emitter voltage (V BE) has a temperature coefficient (TC) of about -2 mV/°C. However, for precision temperature sensors, “about” isn’t good ...

Selecting the right sensor is a critical step in electronic system design, influencing accuracy, reliability, and long-term ...

A European McDonald’s restaurant operator is one of several companies piloting an RFID-based solution designed to provide real-time temperature and location data regarding such items as fresh food, ...

In the first installment of this series, "Calculating a practical hotspot safety margin", we discussed how two-parameter thermal models assume that the entire motor, including windings, exhibits one ...

The $249 Nest Learning Thermostat has a larger display, a better resolution and a far-field sensor for viewing time and temperature information from a distance. It works with Google Assistant and ...
