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.
What kinds of sensors can detect human presence in an enclosed space? Some parameters I can think of that can be used for detection might include sound (talking, breathing, etc.), motion, body heat, microfluxuations in air pressure due to breathing, composition changes of air (increased CO2 / decreased oxygen), image matching software, etc.
