IoT Sensor plus with output to the LoRaWAN® network

TLHALOSO EA SEHLAHISOA
The Wx9xx series transmitters for the LoRaWAN® network are designed to measure temperature using 1 to 4 external Pt1000 probes. The LoRaWAN® network is used to transmit short data messages and is optimized for low power consumption. It operates in the unlicensed radio band, which brings cheaper traffic, but also legislative restrictions – messages can not be sent faster than with a 5 minute interval.
The transmitter performs a measurement every 1 minute. The measured values are displayed on the LCD and are sent over an adjustable time interval (5 min to 24 hour) via radio transmission in the LoRaWAN® network to the cloud data store. Through a common web seshebisi, leru lumella u ho view both actual and historical measured values. Transmitter setup is performed remotely, via the cloud web interface, or locally using a computer connected via the SP003 communication cable. It is possible to set two alarm limits for each measured variable. The alarm is signaled by the symbols on the LCD display and sending an extraordinary radio message. Depending on the capabilities of the cloud used, alarm information is then sent to the end user via email or mobile phone notification.
The device is powered by an internal Lithium battery whose lifetime is dependent on the transmission range and operating temperature and ranges from 3 to 10 years. The battery status information is shown on the display and in every message sent.

KHABANE
For the optimum operation of the devices Wx9xx series it is necessary to ensure their vertical position (with the antenna cover upwards), usually by screwing them on a wall or other suitable vertical surface at the place of installation. The mounting holes are accessible after removing the device cover (see the second page of this manual).
- place the device as high as possible (in rooms place the device at least 150 cm above the floor)
- choose the optimal positioning of the transmitter in terms of radio range (see fig.)

- the devices and all probe cables should be place away from electromagnetic interference sources
HO BONA LE HO TLOA SESEBETSI
The device is supplied with installed battery, but in off state. During the power-on process, the device is also activated in the LoRaWAN® network. The device should therefore be within range of the network in which it will be used and ideally in its target position when turned on.
- to turn device on, use a paper clip to press the control button located behind the hole in the bottom wall of the device (see picture), and release it immediately as soon as the display lights up (within approx. 1 s)
- to turn off the switched-on device press the control button with a paper clip and hold it until the sign OFF lights up (approx. 5)
- in addition to turning the device on and off, the control button also has other auxiliary functions (e.g. turning on the service screen)
USING AND SETTING UP THE DEVICE
Boemo ba feme – message sending interval of 5 minutes ▪ alarms deactivated ▪ remote setting enabled
Activation in LoRaWAN® network – after switching on the device with the control button, it will try to activate in the network using the OTAA system. If the network activation is successful, the radio connection indicator will light up approximately 15 seconds after the sensor is turned on and will remain lit. If the activation is unsuccessful or the data transmission is not reliable, move the device to another place, turn it off and turn it on again for a new activation and parameter setting.
Working with the cloud – you need a PC with internet connection and a web sebatli seo u ka sebetsanang le sona. Tsamaea ho ea atereseng ea leru eo u e sebelisang 'me u kenelle akhaonteng ea hau - haeba u sebelisa COMET Cloud ke moetsi oa transmitter, kenya www.cometsystem.cloud and follow the instructions in the COMET Cloud Registration Card that you received with your device. In the list of your device in the cloud, select the device with the desired ID and start viewing the measured values. The device can be set remotely from the cloud too.
Phetoho ea li-setting tsa sesebelisoa ka ho hokela ho PC – unscrew the device cover and connect it to the SP003 cable with the USB port on the computer. Start the Comet Vision program and make a new device setting. Start the Comet Vision program and make a new device setting.
After you have saved the new settings, unplug the cable and screw the device cover carefully.
