ESP-01 IoT Device Using Wi-Fi, MQTT, and Node-Red
Welcome to another exciting #IoT project tutorial! This video will guide you through building your own ESP-01 Temperature Monitoring Data Logger with Wi-Fi, MQTT, and Node-Red.
Components Needed:
1. ESP-01 Wi-Fi module
2. DS18B20 temperature sensor
3. Breadboard and jumper wires
4. USB to TTL converter for programming ESP-01
5. 3.3V or 5v power supply
6. Node-Red installed on a computer or Raspberry Pi
Step-by-Step Guide:
Connect ESP-01 to USB to TTL converter for programming.
Flash NodeMCU firmware onto the ESP-01.
Wire up the DS18B20 sensor to GPIO2 on the ESP-01.
Install the necessary libraries in the Arduino IDE.
Write the Arduino code for reading temperature and send it to an MQTT broker.

Setting up MQTT Broker:
Install and configure an MQTT broker, either cloud-based or local using Mosquitto.
Node-Red Integration:
Install Node-Red on your computer or Raspberry Pi.
Install MQTT nodes for subscribing to the temperature topic.
Create a Node-Red flow to display real-time temperature data on a dashboard.
