TEMP V3 LoRaWAN 863-870 - Guide utilisateur / User guide version V3.0.0
2.2. Transmission modes
The product allows to measure temperature on 2 probes or 1 probes only, to save the information and to send it according to 3 modes of emis-
sion.
FR
The periodical transmission allows the
temperature to be collected according
Definition
to a specified period of time, to be
saved and sent on a regular basis for
analysis over time.
EN
I want to measure my temperature on
the 2 probes every 30 minutes. I want
Concrete case
to minimize the number of frame per
of usage
day and to optimize the autonomy so
I prefer to send the maximum of data
in each frame without loosing data.

WARNING: the number of data per frame depends on the network used. Here the case is available on a LoRaWAN Network.

S301 = 12 x 1h = 12h
Over threshold transmission
The over threshold transmission enables
to read the temperature according to a
specified period of time but to send the
alarm frame only if a threshold is
over passed.
I want that the product send me an
alarm if the temperature is lower than
10°C on probe 1.

Transmission
Periodical and over threshold
transmission
Mix of the 2 modes to measure
temperature regularly in order to be
alerted if a threshold is over passed and
to save the information to make analysis
over time.
I want to know the temperature on the
2 probes along the day and be informed
if the temperature go under 10°C on
the probe 1. The product will send me a
frame twice a day with the temperature
measured each hour and an alarm if
the temperature is under 10°C on the
probe 1.
