Sunrise
Senseair Sunrise (from Senseair corporation)
Senseair Sunrise is an NDIR type CO2 sensor that uses manufactured LEDs and photodiodes from AKM
Although the sensor accuracy is as high as ± (30ppm + 3% of the reading), the average current consumption is 45μA, so it can be powered by a battery.
It has a built-in Automatic Baseline Correction (ABC) algorithm which periodically performs calibration automatically, so it can be used without further maintenance after installation.
Features
- Low current consumption
- Highly accurate
- Built-in Automatic Calibration Algorithm (ABC Algorithm) (What is the ABC Algorithm?)
- I2C and UART interfaces
