One of the driving forces in the market is related to the intensive development of smart buildings and smart home automation systems that are getting more reliant on the infrared sensor systems to detect motion, estimate occupancy, and more. According to statistics on energy and building efficiency, more than 220 million motion and presence infrared-based sensors have been installed in smart buildings around the globe in 2024 due to the growing popularity of smart office environments, home automation, and lighting systems that are economically and environmentally efficient. In addition, it has been observed that the global market of smart office space has exceeded 8,200 facilities in the year 2024, with each facility having hundreds of infrared-based motion sensors to be used as both energy and security devices.
The segment of Thermal Infrared Sensors is likely to witness considerable growth. Thermal sensors operate on the principle of detecting the heat emitted by objects. Such sensors are employed in high-end applications like thermal imaging, night vision, and industrial temperature sensing. The increasing demand for automotive safety features and advanced driver-assistance systems has created a demand for thermal infrared sensors. This is because thermal infrared sensors are being increasingly employed in the automotive sector. Additionally, the application of thermal infrared sensor technology for real-time monitoring of the environment and the detection of wildfires is being considered. This is because thermal infrared sensors are capable of detecting temperature changes.
Recent developments between 2024 and 2026 highlight growing investments and technological innovations supporting this segment. For example, the launch of the Earth Observation Satellite, EOS-08, by ISRO in August 2024. This satellite was equipped with advanced Electro Optic Infrared (EOIR) technology, which was useful for working in mid-wave and long-wave infrared regions. Infrared technology is used for environmental monitoring, tracking disasters, and studying climate change. Such government-driven initiatives are on an upward trend and are being implemented through satellite technology, bringing thermal infrared technology into sharper focus for the observation of our environment and tracking environmental data.
The scope of infrared technology is expanding from smart infrastructure to industrial automation, automobile safety, and environmental monitoring. This expansion is likely to keep the infrared sensor market on a high growth path in the future. Additionally, advancements in thermal imaging technology are likely to increase the usage of infrared sensors.
