Window sensors are a critical part of any home security system. Learn how they work so you can ensure this last line of defense is there when you need it.

Motion sensors work similarly, only with heat. Most motion sensors rely on a pyroelectric material that activates when it detects a change in temperature. The sensor is separated into two parts.

Tire pressure sensors are a key part of ensuring drivers stay informed about the condition of this crucial piece of automotive equipment.

Notion's second generation of sensors improve battery life, add Nest integration and extend range -- but customization options are still limited.

He’s also built a test rig to compare this sensor with other particle sensors (the DSM501A and Sharp sensors). The data from the Maxim sensor looks good, but it’s not good enough for a Tricorder.

Remote sensors are only compatible with the $249 Ecobee3 model; the $169 Ecobee3 Lite does not work with remote sensors.

MIT researchers have created a new underwater sensor and communication system that doesn't require batteries, and barely uses any power at all. This could ...
