The temperature and humidity sensors come in various models, such as DHT11 and HTU21D. However, due to parameters such as accuracy and sensitivity, they are not suitable for industrial-grade temperature and humidity monitoring. Their accuracy and sensitivity are both poor. Therefore, in this article, we will use the SHT31 temperature/humidity sensor. They are the best … Read more
Introduction This example will demonstrate how to use the ESP8266-based NodeMCU to upload temperature and humidity data collected through the DHT11 sensor to the MQTT cloud service using the MQTT protocol. It will also show how the application side subscribes to these data and processes them. The reason for using the MQTT protocol is that … Read more
