KY-015 DHT11 Temperature and Humidity Sensor Module

KY-015 DHT11 Temperature and Humidity Sensor Module is designed for electronics, IoT, robotics, and Arduino based applications. This module is easy to integrate with microcontrollers such as Arduino UNO, ESP32, NodeMCU, and Raspberry Pi. Suitable for educational, automation, industrial, and DIY electronic projects. Single Bus Digital Temperature And Humidity Sensor DHT11 Module KY-015 Description Digital Temperature and humidity sensor module KY-015 uses DHT11 sensor to provide temperature and humidity values through a digital interface using one single digital pin, therefore there’s no need to use analog input signals. The humidity sensor is capacitive, while the temperature sensor uses a thermistor to sense temperature. This module consist of a DHT11 digital humidity and temperature sensor, a 1 kΩ resistor and 3 male header pins. The DHT11 uses an internal thermistor and a capacitive humidity sensor to determine the surrounding conditions, an internal chip is responsible for converting the readings to a serial digital signal.
