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
