Door sensors detect door position (i.e., open or closed) based on the precise gap between the magnet and the reed switch.

Rather than building ever-larger Coriolis, vortex or ultrasonic sensors, engineers can use smaller measuring paths and combine their outputs to accurately measure flow in large-diameter pipelines.

Wildfires are becoming more frequent and more intense worldwide. Fires often become infernos because of heat, drought and wind, especially in the summer. The problem is compounded by the climate ...

Ukraine is using a vast network of cheap sensors to detect incoming drone threats. Western officials say the West should ...
