Carbon Dioxide (CO₂) Sensor
ZenoSmart LoRaWAN CO₂ Sensor Module is a wireless device designed to accurately measure carbon dioxide (CO₂) levels in both indoor and outdoor environments and securely transmit the data via the LoRaWAN network. Powered by either a 3.6V 19A battery or an external power supply, the sensor can be easily deployed in areas with or without electrical infrastructure. Data transmission occurs every 15 minutes by default and can be adjusted as needed through the IoT platform. Users can remotely monitor devices via zenosmart.com and generate weekly or monthly reports.
The sensor helps manage air quality to prevent the negative effects of high CO₂ concentrations on human health and the environment. With LTE, Wi-Fi, or Helium network connectivity, it enables wide-area monitoring, ensuring safe and efficient CO₂ tracking in both closed and open spaces.
