ZigBee CO2 Sensor

  • Measurement Dual Wavelength NDIR
  • Autocalibration
  • Long term stability and accuracy
  • Internal antenna
  • Slim size
  • Routing function
  • Sampling and transmission rates are configurable
  • Wall mounting

The ZED-CO2-M sensor is a ZigBee battery supplied device which can measure carbon dioxide and regularly send the collected information to one of the gateways of the 4-noks range.
Is possible to set the device in order to manage alarms to ring when its limits are trespassed, because of an exceeding value or of a too small value. It is also possible to schedule the sampling timing and the sending modalities of the measurements in order to increase the duration of the battery.
