Netvox's wireless CO2, temperature and humidity sensor collects and transmits the CO2 concentration in the air along with accurate messages reporting temperature and humidity. The alert messages are sent to a centralised monitoring system via the LoRaWAN® protocol at pre-programmed intervals.
We can supply third-party online wireless sensor monitoring and notification system to view data and set alerts via SMS text and email.
Ask us about our zero-touch provisioning service, this sensor can be supplied pre-configured and ready to go.
