What is inflammation and the steps in the process of inflammation? We often feel redness, heat, swelling and pain at the site of wounds. Actually this is bodyâs defence mechanism to destroy the pathogen. 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.
Motion sensors are sensitive in the 8-12 micrometer range of infrared energy, which is the range that corresponds with the temperature of human skin, about 93 degrees Fahrenheit. Motion sensors detect changes in infrared energy, but only if the change is rapid. For example, if someone walks past a motion sensor it will pick up the change in energy and trigger the alarm. Heating and cooling your home won't trigger an alarm because the change in energy is too slow.
