A new generation NDIR sensors
Electronics with no moving parts makes this sensor robust and resistant to vibrations. Any application with a tough environment or in environments with explosion risk is benefited by the solid state design.
Thanks to the next generation LED technology Senseair Sunrise has a ultra low power consumption. 6 times lower than the other low power NDIR sensors on the markets. Average current 38μA 2.
There is a fundamental relationship between invested power and measurement resolution in all electronic sensors. The more electrical energy you invest in the measurement, the more accurate reading you will get. Therefore, obtaining high resolution measurements using a low power sensor is a challenge. Sunrise is the first NDIR sensor with LED technology that truly saves power while maintaining a high precision. Accuracy (CO2) ±30 ppm ±3% of reading.
Mount and forget your sensor for the next 15 years and it will still be accurate thanks to the built-in self-correcting ABC algorithm. Senseair has used Automatic Baseline Correction for three decades. About 6 million sensors are providing data every millisecond and every 7th day they will calibrate themselves. With wireless applications it will be even more important to rely on a sensor you can mount and forget. Sunrise will continue the line of success.
The design of the sensor is done to optimize the manufacturing process, thus we are staying away from any manufacturing steps that require human handling. The production line is fully automated and the calibration is made in four different steps.
Sunrise can be delivered as a sensor core - calibrated and ready to mount. But you will find more advantages in our other packages: Sensor onBoard and Sensor inCase. As the names suggest we will design and manufacture the board with the sensor or ready-to-use packaging. The advantage is that calibration can be made after the sensor has been mounted and that comes with extended warranties. We will also take responsibility for the design to be optimized around the sensor function (air flow etc).

- Optical solid state
- Ultra Low Power
- High precision
- Mass production
- Self calibrating
LED technology has long been a holy grail. The collaboration with Asahi Kasei (AKM), the company that also invented the Lithium Battery, has now made it possible to use the technology with sustained performance.
Ultra Low Power does not anymore have to come at the cost of accuracy. Sunrise is the new generation Optical Solid State Sensor.
