Example
The product measures temperature, humidity, CO2 concentration, and relative
change in volatile organic compounds every 10 minutes.
Alarms are configured for the product to notify the MQTT broker:
If the temperature exceeds 25°C. This alarm will be disabled if the temperature
falls below 24°C.
If the temperature goes below 19°C. This alarm will be disabled if the
temperature rises above 20°C.
If the CO2 concentration exceeds 1300 ppm. The CO2 alarm will be disabled if
the concentration falls below 1270 ppm.
