Embedded systems are commonly found in consumer, industrial, [[automotive]], [[home appliance]]s, medical, telecommunication, commercial, aerospace and military applications.

[[Telecommunications system]]s employ numerous embedded systems from [[telephone switch]]es for the network to [[cell phone]]s at the [[end user]]. Computer networking uses dedicated [[Router (computing)|routers]] and [[network bridge]]s to route data.

[[Consumer electronics]] include [[MP3 player]]s, [[television set]]s, [[mobile phone]]s, [[video game console]]s, [[digital camera]]s, [[GPS receiver]]s, and [[computer printer|printers]]. Household appliances, such as [[microwave oven]]s, [[washing machine]]s and [[dishwashers]], include embedded systems to provide flexibility, efficiency and features. Advanced [[heating, ventilation, and air conditioning]] (HVAC) systems use networked [[thermostat]]s to more accurately and efficiently control temperature that can change by time of day and [[season]]. [[Home automation]] uses wired and wireless networking that can be used to control lights, climate, security, audio/visual, surveillance, etc., all of which use embedded devices for sensing and controlling.

Transportation systems from flight to automobiles increasingly use embedded systems. New airplanes contain advanced [[avionics]] such as [[inertial guidance system]]s and GPS receivers that also have considerable safety requirements. [[Spacecraft]] rely on [[astrionics]] systems for trajectory correction. Various electric motors — [[brushless DC motor]]s, [[induction motor]]s and [[DC motor]]s — use electronic [[motor controller]]s. [[Automobile]]s, [[electric vehicle]]s, and [[hybrid vehicle]]s increasingly use embedded systems to maximize efficiency and reduce pollution. Other automotive safety systems using embedded systems include [[anti-lock braking system]] (ABS), [[electronic stability control]] (ESC/ESP), [[traction control]] (TCS) and automatic [[four-wheel drive]].

[[Medical equipment]] uses embedded systems for [[Monitoring (medicine)|monitoring]], and various [[medical imaging]] ([[positron emission tomography]] (PET), [[single-photon emission computed tomography]] (SPECT), [[computed tomography]] (CT), and [[magnetic resonance imaging]] (MRI) for non-invasive internal inspections. Embedded systems within medical equipment are often powered by industrial computers.<ref>[http://content.dell.com/us/en/enterprise/oem-industry-solutions-build-your-product-with-dell Embedded Systems Dell OEM Solutions | Dell] {{Webarchive|url=https://web.archive.org/web/20130127080734/http://content.dell.com/us/en/enterprise/oem-industry-solutions-build-your-product-with-dell |date=2013-01-27 }}.

Embedded systems are used for [[safety-critical system]]s in aerospace and defense industries. Unless connected to wired or wireless networks via on-chip 3G cellular or other methods for IoT monitoring and control purposes, these systems can be isolated from hacking and thus be more secure.{{citation needed|date=April 2021}} For fire safety, the systems can be designed to have a greater ability to handle higher temperatures and continue to operate. In dealing with security, the embedded systems can be self-sufficient and be able to deal with cut electrical and communication systems.

Miniature wireless devices called [[mote (sensor)|motes]] are networked wireless sensors. [[Wireless sensor networking]] makes use of miniaturization made possible by advanced [[integrated circuit]] (IC) design to couple full wireless subsystems to sophisticated sensors, enabling people and companies to measure a myriad of things in the physical world and act on this information through monitoring and control systems. These motes are completely self-contained and will typically run off a battery source for years before the batteries need to be changed or charged.
