The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. This tutorial will show how to display - DHT11 data on QIoT Dashboard (using a Seeeduino with W5500 Ethernet Shield).
- "IoT Applications" → "Add IoT applications"
- In "Create a New IoT application"：
- Enter a name for your IoT Application.
- The Rule name and Dashboard name will be automatically generated based on the IoT Application Name.
- Click "Create".
- "Add Thing":
- Enter a name for the Thing (in this sample: "Thingname").
- "Custom" in "Thing Category".
- Click "Add".
- Click the "Thing Resources"button, and enter "Thing Resource".
- In "Add Thing Resource":
- Enter a name for the resource (in this example: "myTemperature").
- Enter a resource ID.
- (The resource ID is used to create a topic in the QIoT broker. This ID should be unique for the device and no duplicates should be allowed for the same device).
- Click "Add".
- Click "Connect to device", and "in Thing Information" choose "MQTT", click "Next", and click "download JSON file".
- In the "Rule" window to set the "MQTT Message":
- Click "MQTT Message In"
- Uncheck "Use custom topic"
- Choose the Thing "Thingname".
- Click "Add", and choose "myTemperature" in "Resources".
- Click "Done", and "Save".
- After setting the Rule, open the Arduino and the JSON file, and then copy the code (username, clientId, host, password, and topic) into Arduino, respectively. After copying, upload the file.
- Return to the Rule tab, and connect the MQTT Message In and Dashboard.
- In the Dashboard tab, you could see a sample temperature.
