Configuration via the NFC IoT Configurator App
Go to the "APPLICATION" section => Configure the sensor sampling
frequency to 600 seconds => Configure the transmission period to 0
seconds.
=> Go to the "TEMPERATURE" section => Enable the high and low
threshold alarm mode => Configure the high threshold detection to 25°C,
the low threshold detection to 19°C, and the hysteresis to 1°C.
=> Go to the "CO2" section => Enable the alarm mode => Configure the
high threshold detection to 1300 ppm and the hysteresis to 30 ppm => Go
to the "APPLICATION" section => Check the threshold status.
=> Apply the new configuration to the product using NFC.
ANNEX 5: PERIODIC AND THRESHOLD
EXCEEDANCE TRANSMISSION
The product allows for periodic measurement of temperature, humidity, CO2 level,
and relative change in volatile organic compounds (VOC), and sends this information
to a MQTT broker at regular intervals.
With the history mechanism, if the sensor sampling frequency is higher than the
transmission frequency, the product will store all measured values in local memory to
transmit them in a single message at the end of the transmission period.
If the product detects a threshold exceedance (both high and low for temperature
and humidity, only high threshold for CO2 and VOC), it sends a message to the
broker to alert the user. A new notification is sent when the values return to normal.
Only the exceeded value is transmitted to the broker.
