This project consists of creating a temperature and humidity sensor using a Wemos D1 mini microcontroller along with a DHT11 sensor. The data collected by the sensor is securely published to an MQTT topic using the TLS/SSL protocol.
- Wemos D1 mini (ESP8266)
- DHT11 temperature and humidity sensor
- Connection to a Wi-Fi network with internet access
- PlatformIO development platform
- Necessary libraries for the DHT11 sensor and MQTT communication
- MQTT broker with TLS/SSL support (e.g., Mosquitto)
-
Hardware:
- Connect the DHT11 sensor to the data pin of the Wemos D1 mini.
- Power the Wemos D1 mini with an appropriate power source.
-
Software:
- Open the project in PlatformIO.
- Ensure that the
platformio.inifile is configured correctly with the compilation and device setup options. - Install the necessary libraries for the DHT11 sensor and MQTT.
- Configure the Wi-Fi connection parameters and MQTT server settings in the code.
- Compile and upload the code to the Wemos D1 mini.
Once the device is powered and connected to the Wi-Fi network, it will begin collecting temperature and humidity data using the DHT11 sensor. This data will be securely sent to an MQTT broker using the TLS/SSL protocol. You can subscribe to the corresponding MQTT topic to receive and process the data as needed.
- It is important to ensure that the MQTT broker the device is connecting to supports secure connections via TLS/SSL.
- Additional security measures, such as authentication on the MQTT broker, are recommended as needed for your specific application.
