A new generation NDIR sensors with Optical Solid-State design

Electronics with no moving parts makes Senseair Sunlight HC-R 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 HC-R 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.

Senseair Sunlight HC-R is a module that is designed for simple integration into products. Senseair Sunlight HC-R can be used in a wide range of refrigerant applications based on R32.
