Functions of the app:
■
Display of the instrument information
■
Display of the instrument status
■
Reading the current measured value
■
Activating and deactivating the instrument (LoRa radio)
■
Manual join request for the LoRa network
Executing NFC command
In order to execute an NFC command, the mobile device, with the “myWIKA wireless
device” app open, must be held up to the NFC symbol on the radio module.
Reading the current instrument status
The instrument status and the current measured pressure value can be read via an NFC
command. To do this, hold the NFC-capable end device, with the “myWIKA wireless
device” app open, to the instrument and follow the instructions on the screen.
The instrument temperature displayed in the app does not correspond to the
process temperature. If the instrument temperature drops below -20 °C [-4 °F],
the measuring frequency will be reduced to reduce the battery consumption.
As soon as the instrument temperature is above -17 °C [-1.4 °F], the preset
measuring frequency will be adopted.
6.4 Battery status
The battery life is transmitted via LoRaWAN
®
as a percentage value and in the form of
the battery voltage (nominal value: 3.6 V).
Since the battery life is influenced by many factors, e.g. measuring and sending rate,
spreading factor and ambient and process temperatures, this value is only an approximate
value. The calculation of the approximate value is based on a constant ambient
temperature of 20 °C [68 °F].
For values below 25 %, a battery change is recommended. If the battery is completely
discharged, no more values are transmitted via the radio interface. The mechanical
on-site display is not impaired.
The battery voltage (nominal value: 3.6 V) can also be read via the app “myWIKA wireless
device” and the NFC interface.
6.5 Integrating the instrument
The model PGW23.100.11 can be integrated into a IIoT infrastructure via LoRaWAN
®
.
The model PGW23.100.11 is connected to a LoRaWAN
®
gateway and the measured
values are transferred to the IIoT infrastructure (e.g. platform, PC, mobile device, etc.) at
freely configurable intervals.
