Description
The DHT11 Temperature and Humidity Sensor Module (KY-015) is a low-cost, easy-to-use digital sensor designed for measuring environmental conditions. It provides accurate temperature and humidity readings in a compact form factor, making it ideal for Arduino, Raspberry Pi, ESP32, and IoT-based projects.
This module features the DHT11 sensor, which includes a resistive humidity sensing component and an NTC temperature sensor. It outputs data in digital form, eliminating the need for complex analog-to-digital conversion. The sensor is widely used in weather stations, indoor climate monitoring, and smart home automation systems.
The KY-015 module has three pins (VCC, GND, and Data) and can operate on a 3.3V to 5V power supply, making it compatible with various micro controllers.
