LoRaWAN Smart Building COMFORT - Guide utilisateur / User guide version V2.1.1
2.3.1 Three modes of sending possible
The device can measure the temperature and humidity in a room, save this information and send it in three transmission modes.
Periodic transmission
Periodic sending allows data to be
collected in a specified period of time,
Definition
to be saved and sent on a regular basis
for analysis over time.
I want my device to read the tempera-
ture and humidity every 3 hours, this in-
Practical exam-
formation is saved and all my backups
ple of use
are sent to me once a day.
•
Period of acquisition
= 5400 (5400 seconds = 3 hours)
Backup frequency
•
= 1 (1 backup every 3 hours)
•
Frequency of transmission
= 8 (8 X 3 hours = 24 hours)
• Type of alarm T° (S330)
= 0 (alarm disabled)

• Type of humidity alarm (S340)
configuration
= 0 (alarm disabled)
CAUTION: The information sending capacity will depend on the network used. Here the case considered works with a technology LoRaWAN.

Reading/
Sampling
The sending of a frame on exceeding
a threshold makes it possible to read
data according to a given period and
to send an alarm only if one of the
thresholds is exceeded
I want my device to send me an alarm
when 24°C in my room is exceeded
with a reading every 10 minutes. I do
not want an alarm for humidity.
(S321)
•
= 300 (300x2 = 10 minutes)
(S320)
•
= 0 (no periodic sending)
(S301)
• High threshold definition (S331)
= 240 (+24°C)
• Type of alarm T° (S330)
= 1 (high threshold)
• high threshold hysteresis (S330)
= 20 (2°C) My room will have returned
to the "normal" temperature below
22°C.
• Type of humidity alarm (S340)
= 0 (alarm disabled)
Frequency of transmission =
number of backups (logs) between each sending S301
= 8x3 hours = 24 hours
Backup frequency =
S320 = 18 x 10 min = 3 hours
Transmission over threshold
Period of acquisition
(S321)
Frequency of transmission
(S301)
Periodic transmission and over
threshold
Mix of the two modes in order to be
able to reading regularly to receive
alerts if the threshold is exceeded and
to save the information regularly to
make the analysis over time.
I want my device to run every 10
minutes. I want the data saved every 3
hours and the information sent to me
once a day.
If the temperature exceeds 24°C I want
an alarm sent to me. I do not want an
alarm for humidity.
