Radio Climate Monitor

You will be able to see dashboard with temperature, humidity, ambient light and atmospheric pressure in Node-RED and view the data on your smart phone using the Blynk cloud and mobile app.

Block Concept

1. Build hardware

You will need a Climate Monitor Kit for this one, The assembly is easy, the only thing that can go wrong is the Mini Battery Module, you can actualy put that one wrong side up.

You can also watch a video on how to assemble the whole kit.

2. Flash firmware

• Download HARDWARIO Playground,
• Flash firmware to the Core Module
• Firmware is named: bcf-radio-climate-monitor
• How to flash firmware is shown in the documentation.

3. Pair the Core Module

You need to pair the Core module with the Radio dongle that you are using, follow the instructions below to see how it is done.

• Connect your USB Radio Dongle to your computer.
• Open HARDWARIO Playground

• Click Start Pairing the LED on the dongle should start blinking
• Connect the device that you want to pair into your computer or insert the batteries.
• Wait for the device to appear in the table
• It should add the device with the Alias: climate-monitor:0

4. Import flow

• Switch to Functions tab
• Import the flow for this project. Just copy everything, go to Menu -> Import -> Clipboard and paste it there.
• After Import hit Deploy in the top right corner to upload the change.

5. Blynk integration

This project is supposed to work with the Blynk. How to set up blynk is explained in HARDWARIO tutorial.

If you did the whole tutorial you should have a downloaded Blynk app in your phone.

Click the QR code icon in the top right corner and scan the following QR code.

You will need an Auth Token to setup the Blynk and Node-RED connection, you can email it to you through the app.

• Click on the Settings in the project that you just imported

• Click on Email all

• Now click Play in the project to start it

• You need to put the Auth Token from the email into the Blynk server setting that you did in the tutorial above.

6. Test your device

If you did everything right, you should see something like this

The values will update each time the Climate Monitor Kit sends new data to the Node-RED.

Summary

With this project done, you can do some basic environmental measurement. You can do a lot more with the HARDWARIO IoT Kit. This was just a starter project to get you know the environment.

If you want to see more starter projects like this, you can visit projects in this category.

Feel free to ask and I will try to answer any question.

• Visit HARDWARIO page on hackster.io for more interesting projects or go directly to their website
• Go to HARDWARIO documentation to learn more about their modules and other possibilities of the platform.
• Try more firmware from HARDWARIO Playground or write your own, it is easy to start.
• Because everything is Open source you can get all firmware on GitHub, get some inspiration and try to make your own applications.
• Get your own HARDWARIO Hub to replace your computer in this project so you have always access to your applications.
• Check out more applications that can be used with HARDWARIO IoT Kit in Integrations section.
