Rancan Building Temperature Measuring Devices and Air Moisture Using DHT 11 Sensors Based on ESP 8266 Microcontroller

Introduction

In today's world, the use of sensors in various fields is increasingly widespread to help human work. One of the most commonly used sensors is the DHT11 sensor, which can measure the temperature and humidity of the air accurately. This article will discuss the design and implementation of the temperature and humidity measuring device based on the ESP8266 microcontroller combined with a DHT11 sensor, and is equipped with an automatic fan to regulate room temperature.

The Importance of Temperature and Humidity Measurement

Temperature and humidity are two of the most critical factors that affect human comfort and health. A comfortable temperature range is between 20-25°C, while a relative humidity of 40-60% is ideal for human health. However, these conditions can vary depending on the location, season, and other factors. Therefore, it is essential to have a reliable and accurate temperature and humidity measuring device to maintain a comfortable and healthy environment.

Design and Implementation of the Temperature and Humidity Measuring Device

The temperature and humidity measuring device consists of several main components:

DHT11 Sensor

The DHT11 sensor is a digital temperature and humidity sensor that can measure the temperature and humidity of the air in real-time. It has a high accuracy of ±2°C and ±5% RH, making it an ideal choice for temperature and humidity measurement.

ESP8266 Microcontroller

The ESP8266 microcontroller is a Wi-Fi enabled microcontroller that can process data from the DHT11 sensor, control fans, and send data to other devices. It has a built-in Wi-Fi module that allows it to connect to the internet and send data to other devices.

Fan

The fan is an essential component of the temperature and humidity measuring device. It is used to regulate room temperature by blowing air when the temperature exceeds the specified limit.

LCD Screen (Optional)

The LCD screen is an optional component that displays temperature and humidity data directly. It is useful for monitoring temperature and humidity data in real-time.

Wi-Fi Network

The Wi-Fi network is a critical component that allows temperature and humidity data to be monitored remotely through smartphones or other devices.
