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
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
Overview Previously, I wrote a tutorial on building a temperature and humidity monitor with 20 lines of code, and I also promised to write a tutorial without any coding. After a long delay, I finally finished it. Some content is excerpted from the Baidu Cloud IoT Platform documentation. Development Board NodeMCU is an open-source development … Read more
Temperature is a physical quantity that we often encounter and can intuitively feel, such as needing to add clothing when the weather gets cooler or blowing on food that is too hot. It is also necessary to measure temperature accurately, for example, the normal body temperature of humans is 37.5℃, and the boiling point of … Read more
Experimental components include: LED, switch and temperature and humidity sensor. 1. Connection of LED LED (Light Emitting Diode) is a solid-state semiconductor device that can convert electrical energy into visible light. It directly converts electricity into light. The core of the LED is a semiconductor chip, one end of which is attached to a bracket, … Read more
