This is a fun little project I built to learn how to connect an ESP32 to the world of IoT. Basically, I read temperature and humidity from a DHT11 sensor, send that data via MQTT, and visualize it on ...

MQTT, which stands for Message Queuing Telemetry Transport, enables smart devices, particularly those with low processing power, to communicate locally without requiring an intern ...

This project demonstrates an end-to-end IoT system using an ESP32-WROOM-32 dev board, I2C Temperature Sensor, MQTT protocol, and a Node-RED dashboard. The system reads sensor data from the temperature ...

For years we’ve seen a trickle of really interesting home automation projects that use the Node-RED package. Each time, the hackers behind these projects have raved about Node-RED and now I’ve joined ...
