Temperature Sensor Market Size, Share, Opportunities, And Trends By Type (Resistor Temperature Detectors, Thermocouples, Infrared, Thermistors, Others), By Connectivity (Wired, Wireless), By End-User Industry (Automotive, Oil And Gas, Food And Beverage, HVAC, Consumer Electronics, Chemical, Others), And By Geography - Forecasts From 2025 To 2030

Temperature sensor market is projected to grow from US$6.65 billion in 2025 to US$8.66 billion in 2030 at a CAGR of 5.43% during this period. 

Advancements in nano and micro technology, along with rising demand from sectors like smartphones, wearable bands, patient monitoring devices, consumer electronics, and industrial and healthcare applications, are driving the temperature sensor market. However, high initial costs of advanced sensors may hinder growth.

Temperature sensors are electronic devices that measure temperature via electric signals, used across systems to monitor heat and alert users. Technological progress and demand from healthcare, automotive, consumer electronics, oil and gas, and food and beverages sectors fuel the global market.

Global demand for portable healthcare equipment, including health monitoring and patient monitoring systems, has boosted the need for temperature sensors. Factors like viral infections, lifestyle changes, and a growing geriatric population further increase demand for these devices, where temperature sensors enable continuous monitoring in wearables—a key market driver.

In the automotive sector, demand for comfort, reliability, and advanced features has heightened the use of temperature sensors. Applications include in-vehicle temperature, outside air, engine coolant, exhaust gas, seat/steering wheel heating, and battery/e-motor management in electric vehicles (EVs). In EVs, sensors prevent battery overheating during charging and control motor temperatures, supporting market growth through the forecast period.

By type, the market includes thermocouples, resistor temperature detectors (RTDs), thermistors, and others. Thermistors, thermally sensitive resistors, show precise resistance changes with temperature shifts. Integrated circuits offer digital or analog outputs proportional to absolute temperature, with small packages, fast response, and low thermal mass. RTDs provide high accuracy and repeatability, while infrared (IR) sensors detect electromagnetic waves (700 nm to 14,000 nm), reading moving objects effectively.

By end-user, the market spans automotive, food and beverages, oil and gas, consumer electronics, HVAC, chemicals, and others. Automotive is poised for rapid growth, using sensors to monitor vehicle gases and liquids. In food and beverages, sensors ensure safety by triggering alarms when temperatures deviate, preventing bacterial contamination.

Production relies on raw materials like nickel, cobalt, manganese, copper, and iron alloys, sourced from third-party suppliers. Availability and price fluctuations—driven by economic growth, trade tariffs, emerging markets, natural disasters, demand, wars, political events, and currency shifts—impact profitability. Advances in technology and material science, aided by computer-integrated manufacturing, have intensified competition, but high initial manufacturing costs may limit market expansion.
