Learn how to program the ESP32 or ESP8266 boards with MicroPython to publish DHT11 or DHT22 sensor readings (temperature and humidity) via MQTT to any platform that supports MQTT or any MQTT client. As an example, we’ll publish sensor readings to Node-RED Dashboard....
Learn how to display temperature and humidity readings from a DHT11/DHT22 sensor in an SSD1306 OLED display using an ESP32 or an ESP8266 with Arduino IDE. The idea of using the OLED display with the ESP32 or ESP8266 is to ilustrate how you can create a physical user interface for your...
Get started with InfluxDB using the ESP32 board. InfluxDB is an open-source time series database (TSDB). So, it is ideal to store sensor data with timestamps over a determined period of time.
