NB-IoT CO2 Traffic Light

NBS-180 - Narrowband IoT

Local Signaling and fast Notifications

The device measures continiously the CO2 concentration in the ambient air. Following signaling scheme is provided by the NBS-180:

  • <1000 ppm: Green LED blinks every 10 minutes
  • 1000-1500 ppm: Yellow LED blinks every 5 minutes
  • >1500 ppm: Red LED blinks every minute, acoustic signal via integrated buzzer, notification via email to the person in charge (configurable)


  • CO2
  • Temperature
  • Relative Humidity
  • Optional VOC / TVOC / eCO2 Air Quality
  • Proactive "Battery Low" message
  • Intelligent Battery Saving Mechanisms
  • Firmware update-capable via radio
  • Protocols: MQTT, LwM2M
  • Actuators: Very bright R$GB-LED (green, yellow, red), integrated buzzer
