What is IoT (Internet of Things)? Imagine your appliances thinking for themselves: the refrigerator knows when the milk is running low and orders a delivery; the soil in the flowerpot feels dry and automatically notifies the water pump to water it. IoT (Internet of Things) is a technology that connects various devices through the Internet, … Read more

DHT11 is a low-cost temperature and humidity sensor that uses a moisture-sensitive resistor to measure humidity, employs a digital temperature sensor for temperature testing, and processes the data using a microcontroller with serial output. The DHT11 costs about 4 yuan, though it is not aesthetically pleasing. The DHT22 is priced around 15 yuan, and while … Read more
Implementing DHT11 Temperature Sensor Parameters with C# on ESP32 Microcontroller[1] Welcome to C# enthusiasts, in this article we will use the C# nanoframework to develop a program to read temperature and humidity from the DHT11 sensor on the ESP32 microcontroller. To implement this, we need to prepare and configure the environment for ESP32. You can … 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
