The R290 refrigerant leak sensor is a smart infrared refrigerant detection module. It uses NDIR principle to detect refrigerants, which has excellent selectivity and is not dependent on oxygen. This module is a compact, high-performance module made by closely combining mature infrared absorption gas detection sensors with micro-machining and sophisticated circuit design.

Primarily used in hydrogen fuel cell engines and hydrogen supply systems, it monitors hydrogen leaks inside and outside vehicles. Employing MEMS technology, it tightly integrates mature detection techniques with high-quality circuit design, exhibiting excellent electromagnetic interference resistance, superior repeatability, and product stability. It represents a domestic alternative.

AQS is a digital, low-power, miniaturized module used in automotive air conditioning systems. This module combines a MOS gas sensor, MEMS manufacturing processes, and a high-performance microprocessor to detect the air pollution level in the vehicle's external environment. Installed at the air intake of the air conditioner, it detects the air quality about to enter the vehicle.
