LoRaWAN DELTA P - Guide utilisateur / User guide version V1.0.0
2.1.5 Three transmission modes to meet needs
The device can mesures a delta pressure, save this information and send it in three transmission modes.
Periodic transmission allows data to
FR
be collected in a specified period of
Definition
time,
to be saved and sent on a regular
basis for analysis over time.
I want to take a reading of my
EN
pressure delta every half hour. I want
to minimize my number of uplinks to
Specific user
optimize my autonomy, so I want to
situation
put as many readings as possible in
each data frame without losing any
data.

In the use
Paragraph 2.1.5.01
CAUTION: The ability to transmit information will depend on the network used. Here, the mentionned cases works with LoRaWAN technology.
The complete list of registers can be found in section 3.4.

Transmission over threshold
The transmission of a frame over
threshold makes it possible to read data
according to a given period and to send
an alarm only if one of the thresh-
olds is exceeded.
I want the product to alert me if my pres-
sure delta falls below 100 Pa.

• Lower threshold (333) = 100 (in Pa)
• Low threshold hysteresis
(S334) = 10 (in Pa) the alarm is triggered
only when pressure delta exceeds 110 Pa.
Paragraph 2.1.5.02
Backup period = number of readings
Sending
Periodic transmission and over
threshold
Mix of the two modes in order to be
able to read regularly to receive alerts
if the threshold is exceeded and to save
the information regularly to make the
analysis over time.
I want to know the pressure delta of
my VMC during the day and be alerted
if the pressure delta falls below 100
Pa. My product will send me an hourly
reading of the pressure delta twice per
day and trigger an alarm if my pressure
delta falls below 100 Pa.
