New Generation NDIR Sensor (Non-Dispersive Infrared Absorption Method)
The solid-state optical system and the latest electronics have enabled the realization of sensors that are robust and highly resistant to vibration. This solid-state design demonstrates advantages even in harsh environments and applications with explosion risks. The Senseair Sunlight R290, which is the first NDIR sensor to introduce an LED light source, is a truly energy-efficient sensor that maintains high measurement accuracy. The Senseair Sunlight R290 is designed for mass production sensors, achieving complete traceability through serial numbers in its key components and manufacturing processes. The sensor is individually calibrated and can be used maintenance-free for a long period with an expected lifespan of over 15 years by enabling the built-in ABC algorithm (automatic baseline correction function). It features UART (Modbus) and I²C as communication interfaces. The Senseair Sunlight R290 is a sensor module designed for integration into mass-produced host devices and can be used in a wide range of applications as a sensor for measuring R290-based refrigerants.
