Sunlight R290

Electronics with no moving parts makes Senseair Sunlight R290 robust and resistant to vibrations. Any application with a tough environment or in environments with explosion risk is benefited by the solid-state design. It is also the first NDIR sensor with LED technology that truly saves power while maintaining a high precision.

Senseair Sunlight R290 is designed for high volume production with full traceability by sensor serial number on all manufacturing processes and key components.

Every sensor is individually calibrated and is provided with UART (Modbus) and I2C interface. With the ABC function activated, the sensor is maintenance free.

This product is a module that is designed for simple integration into products. Senseair Sunlight R290 can be used in a wide range of refrigerant applications based on R290.

We at Senseair believe in quality and accuracy. When it comes to gas measurements, you want a sensor that you can always trust – without the need for maintenance. Equipped with a self-correcting algorithm (ABC: Automatic Baseline Correction), you can mount your Sunlight sensor and then leave it alone for 15 years while maintaining a robust system. Our Sunlight sensors are optimized for battery and wireless applications, or in places where you need a reliable and secure sensor with a long life.

Senseair’s Sunlight R290 can be used in a wide range of refrigerant applications. Using LED as the light source and a photodiode in the sensor section ensures highly safe operation of equipment that uses flammable refrigerants (R290).
