How to Use QBoat Sunny to build WiFi Applications

In this tutorial, we will use transfer information from DHT11 (connected to LinkIt 7697) to QBoat Sunny via HTTP. Then, the QIoT Suite Application will output the temperature every 30 seconds, and humidity every 60 seconds.

What You’ll Need:

  • QBoat Sunny
  • Files used: Download Here
  • MediaTek LinkIt 7697
  • DHT11 Temperature and Humidity Sensor
  • AP Wireless Router

Create and Setup QIoT Application

  1. Open QIoT Suite > IoT Applications > Import > select test.json

Connect LinkIt 7697

  1. Connect the DHT11 to LinkIt 7697.
    • GND to GND
    • VCC to 3V3
    • Signal to P3
  2. Download and Install the Arduino IDE here
  3. Open dht11-wifi.ino in Arduino IDE and change network SSID and password accordingly.
  4. Upload dht11-wifi.ino to LinkIt 7697 via Arduino IDE.
  5. Open the Serial Monitor (Ctrl + Shift + M). The serial monitor will show LinkIt’s IP address. Copy this IP address.

Connecting QIoT Suite to LinkIt

  1. Head back to QIoT Suite and double-click the temp node.
  2. Paste the DHT11’s temperature URL into the URL field, then give this node a name.
    URL: http://<LinkIt’s IP>/temp
    Name: temp
  3. Click Done
  4. Repeat Steps 1-3, for DHT11’s humidity URL.
    URL: http://<LinkIt’s IP>/humi
    Name: humid
  5. Click Save.
  6. Start the Application by pressing the start node, then observe the output data by going into the debug tab.
