The DHT11 is a sensor that can measure both temperature and humidity and is preferred in many projects due to its low cost and ease of use. The DHT11 consists of two main components: a temperature sensor and a humidity sensor. Learn more about the main features of the DHT11 sensor and how it works:
Temperature and humidity measurement:
DHT11 can measure the temperature and humidity of the environment. This is suitable for weather monitoring, climate control, greenhouse control and many other applications.
The DHT11 is a sensor that sends temperature and humidity data in digital form. This allows easy data processing and transfer to microcontrollers.
The accuracy of DHT11 for measuring temperature is ± 2 °C and for measuring humidity is ± 5 °C. This level of accuracy ensures that it provides results that are accurate enough for most projects.
The DHT11 sensor uses a thermistor (temperature sensor) and a humidity element to measure the temperature and humidity of the surrounding environment. When the sensor is connected to a microcontroller or a device like Raspberry Pi, it can send the temperature and humidity measurement data as a digital signal. The sensor measures temperature and humidity at certain intervals. It then converts these measurements into digital signals and transmits them. The principle of operation of the sensor involves the conversion of indoor temperature and humidity values into electrical signals, which allows accurate measurement of environmental conditions.
DHT11 sensors are commonly used in Internet of Things projects, weather stations, smart home automation and similar applications to measure temperature and humidity. They can be easily integrated into platforms such as Arduino, Raspberry Pi and other microcontroller systems.
