Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is slightly less dense than air.

It is toxic to hemoglobic animals (both invertebrate and vertebrate, including humans) when encountered in concentrations above about 35 ppm, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions.

In the atmosphere, it is spatially variable and short lived, having a role in the formation of ground-level ozone.

A smoke detector is a device that senses smoke, typically as an indicator of fire.

Commercial security devices issue a signal to a fire alarm control panel as part of a fire alarm system, while household smoke detectors, also known as smoke alarms, generally issue a local audible or visual alarm from the detector itself.

A security alarm is a system designed to detect intrusion – unauthorized entry – into a building or area.

Security alarms are used in residential, commercial, industrial, and military properties for protection against burglary (theft) or property damage, as well as personal protection against intruders.

Car alarms likewise protect vehicles and their contents.

Prisons also use security systems for control of inmates.

A thermostat is a component which senses the temperature of a system so that the system's temperature is maintained near a desired setpoint.

Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role.

Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, associated passive electrical components, and interconnection technologies.

Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit.
