Global R290 Sensor Market Strategic Research Report

Scope of the Report

The global R290 Sensor market size is predicted to grow from US$ 25.72 million in 2025 to US$ 69.02 million in 2032; it is expected to grow at a CAGR of 15.0% from 2026 to 2032.

R290 Sensor is a type of gas sensor designed to detect the concentration or leakage of R290 refrigerant in refrigeration systems. R290, also known as propane, has the chemical formula C₃H₈ and is classified as a highly flammable natural refrigerant. It is widely used in heat pumps, air conditioners, commercial refrigeration equipment, refrigerated display cabinets, refrigerators, and industrial refrigeration systems. R290 sensors typically use infrared, photoacoustic, semiconductor, or other gas-sensing technologies to continuously monitor R290 concentrations in the surrounding air. When the detected concentration reaches a predefined safety threshold, the sensor sends an alarm or control signal to the equipment control system, helping reduce the risk of fire or explosion caused by refrigerant leakage. In this study, R290 Sensors mainly include leak detection sensors, sensor modules, and intelligent detection modules used in refrigeration and HVAC equipment, excluding general-purpose propane sensors used only for LPG alarms, fuel gas monitoring, or industrial process measurement.R290 Sensors are generally priced at approximately USD 20–80 per unit for mainstream OEM applications, although prices vary significantly by sensing technology, accuracy, certification, output interface, and order volume. Basic semiconductor/MOS sensors may cost around USD 5–20/unit, while NDIR and photoacoustic R290 sensor modules typically range from USD 25–80/unit. High-performance industrial or intelligent leak-detection modules can reach USD 80–200 or more per unit. For reference, Senseair Sunlight R290 is currently listed at about USD 28.7/unit at 250-piece volume, while Amphenol SGX INIR7-R290 is around USD 55/unit at 100 pieces; specialized industrial NDIR products can exceed USD 190/unit. The upstream industry chain mainly includes infrared emitters, MEMS components, semiconductor sensing materials, optical filters, microcontrollers, ASICs, housings, connectors, and calibration gases. Midstream manufacturers integrate sensing elements, signal-processing circuits, compensation algorithms, communication interfaces, and safety functions into calibrated sensor modules. Downstream customers mainly include heat pump, air-conditioning, commercial refrigeration, refrigerator/freezer, cold-chain, industrial refrigeration, and transportation refrigeration equipment manufacturers.
