What is inflammation and the steps in the process of inflammation? We often feel redness, heat, swelling and pain at the site of wounds.

Tissue damage caused by wound or invading pathogenic organisms induces a complex sequence of events collectively known as inflammation.
A flame detector is a sensor designed to detect and respond to the presence of a flame or fire. Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system.
TechHive. A new smart themostat from Ecobee tries to have a more accurate take on automatic temperature adjustments, using sensors to figure out where people are.

But that motion sensor isn't really useful if the thermostat sits in some rarely-inhabited part of the house.
