SEA Company begins a series of news to introduce our customers to innovative and popular products manufactured by the American company Littelfuse. Modern Littelfuse devices are vital components in virtually every industry that uses electricity, from consumer electronics to cars and industrial equipment. This article is devoted to smoke and heat alarms.
Building automation is no longer perceived by people as something unattainable and difficult to implement in everyday life. Smart homes are equipped with intelligent technologies that make life more comfortable and energy efficient. When designing a smart home, special attention should be paid to safety sensors, because safety is almost the most important thing in the house.
Littelfuse offers protection, management and control technologies to increase safety, reliability and energy efficiency of buildings.
Market trends and factors affecting smoke and heat alarms
- Global supplies of smoke detectors are expected to grow from 98 million in 2020 to 150 million in 2025 (as shown on a graph).
- Raising awareness of the fire safety of all buildings and raising their regulatory framework is a key factor for global growth.
- The commercial segment is the largest one at the moment, accounting for more than half of sensor sales. The housing segment is expected to expand the fastest due to population growth and urbanization.
- America and Europe are currently the largest markets, but the Asia-Pacific region is the fastest growing one.
- Wireless smoke detectors are battery powered and can be connected to Wi-Fi to be a part of a smart home or building ecosystem.
