Introduction

The MClimate CO2 Display lite the lite version is equipped with temperature and humidity sensor, LUX sensor and NDIR CO2 sensor. Featuring smaller 1.54” e-ink screen the device is showing the current levels of CO2 as well as historical trends. The data from the CO2 Display lite can be used in any LoRaWAN® compatible system, incl. Building Management Systems to control demand-based ventilation. Sensor information can be exposed as datapoints in Modbus, BACnet and KNX systems through the use of a special gateway.

Prerequisites

To continue with this guide we will need the following:

• CO2 Display lite Temperature and humidity sensor

• LoRaWAN® gateway (in our case UG56 LoRaWAN® Gateway)

• Configured integration on networks server and ThingsBoard

• Network Server account

• ThingsBoard account

Device connection

Device configuration

To connect and send data we should configure the device and network server. At first we are going to configure the device, and save required information for network server configuration. To add a device to network server and get information from it, we will need the following device parameters:

• Device EUI – device identifier
• Application EUI – Application identifier
• Application Key – Application key to identify device

To configure the device we also need to add it to a network server, so select the network server your gateway is connected to:

• ChirpStack
• TheThingsStack
• TheThingsIndustries
• Loriot

Add a device on the Chirpstack

We need to add a device on the Chirpstack.

To add a device, you can follow next steps:

1. Login to Chirpstack server.
2. Go to the Device profiles page and click on Add device profile button.
3. Fill the fields and click on Submit button.
4. Go to the Applications page, click on your application and press Add device button.
5. Fill parameters with values from the device configuration. Then choose previously created device profile and click on Submit button.
6. Put your Application key to the field and click on Submit button to save the device.

Login to Chirpstack server. Go to the Device profiles page and click on Add device profile button. Fill the fields and click on Submit button. Go to the Applications page, click on your application and press Add device button. Fill parameters with values from the device configuration. Then choose previously created device profile and click on Submit button. Put your Application key to the field and click on Submit button to save the device.

Uplink converter in ThingsBoard integration

Step 1: Download the JSON file

Download the JSON file with the uplink converter settings by clicking the button below.

Download uplink converter for ChirpStack integration.

Step 2: Import the Uplink converter into ThingsBoard

After downloading the file with the Uplink converter configuration, import it into ThingsBoard:

1. Navigate to the “Data converters” page in the “Integration center” section.
2. Click the ”+” icon in the top-right corner of the page and select “Import converter” from the drop-down menu.
3. Drag and drop the downloaded JSON file (containing the uplink converter configuration) into the import window, then click “Import”.
4. The uplink converter is now successfully imported.

Navigate to the "Data converters" page in the "Integration center" section. Click the "+" icon in the top-right corner of the page and select "Import converter" from the drop-down menu. Drag and drop the downloaded JSON file (containing the uplink converter configuration) into the import window, then click "Import". The uplink converter is now successfully imported.

Step 3: Replace the Uplink converter in the ChirpStack integration

Now, let’s update your ChirpStack integration to use the new uplink converter:

1. Go to the “Integrations” page in the “Integration center” section.
2. Click on your ChirpStack integration to open its details window.
3. Enter edit mode by clicking the orange pencil button in the top-right corner.
4. Replace the existing uplink converter with the imported one.
5. Don’t forget to save your changes!

Go to the "Integrations" page in the "Integration center" section. Click on your ChirpStack integration to open its details window. Enter edit mode by clicking the orange pencil button in the top-right corner. Replace the existing uplink converter with the imported one. Don't forget to save your changes!

Check data on ThingsBoard

After the device is connected to the network server and ThingsBoard, you can check received and converted data on the platform for this device.

To do this, open Entities menu section and select Devices. Click on the device name to open the device details page. Go to the Latest telemetry tab to see the latest telemetry data received from the device.

Conclusion

Now you can easily connect your CO2 Display lite Temperature and humidity sensor and start sending data to ThingsBoard.
