Temperature sensors help control heating, cooling, safety systems and industrial processes, making them essential in modern technology. They provide accurate temperature sensing in air, liquids, solids or electronic systems, ensuring efficiency, comfort and safety. As such, these devices are widely used in homes, factories, vehicles, hospitals and laboratories, specifically in smart thermostats, medical equipment, engines and environmental monitoring.
Globally, this category has a billion-dollar market and will continue to grow. Based on Mordor Intelligence’s projection, it will reach $9.93 billion in 2026 and increase to $13.41 billion in 2031 at a CAGR of 6.2 percent. The Asia-Pacific region will lead with a CAGR of 7.05 percent during the period.
In China, typical temperature sensors include mainly thermocouples, RTDs and thermistors in wired and wireless configurations. Water-resistant types, with IP65 or above rating, are available as well. All meet UL, CE and RoHS standards.
To broaden this product selection, Chinese manufacturers are pursuing R&D on smaller temperature sensors with higher sensitivity and reliability. Such initiatives also include smart types that can monitor temperature and humidity data via an app in real-time. An example is Soan’s IP66-rated sensor that can be linked to automatic watering devices for self-operating irrigation.
Companies use metal wires, insulation materials and shells from domestic or foreign providers depending on buyers’ preferences. The cost of these manufacturing inputs is expected to remain stable and keep sensor prices unchanged in the coming months.
