In this tutorial, we will learn how to publish sensor readings to ThingSpeak using ESP32 and ESP-IDF. ThingSpeak is an IoT analytics platform that let us store and read data from the cloud. This cloud platform provides an API that allows users to send data by making an HTTP request to that API. We will … Read more
In this tutorial, we will build an ESP32 web server using ESP-IDF that will display BME280 sensor readings. BME280 sensor is widely used in electronic projects to measure ambient temperature, barometric pressure, and relative humidity where low power consumption is required. The web server will act as a weather station by displaying temperature, humidity, and … Read more
In this project, we will learn to publish BME280 sensor readings to Node-Red with ESP32 MQTT using ESP-IDF. We will perform MQTT communication with ESP32 and Node-Red and publish and subscribe to MQTT topics. The ESP32 will act as an MQTT client publisher and Node-Red will act as a subscriber. Using MQTT protocol, the ESP32 … Read more
