KY-015 DHT11 Digital Temperature Humidity Sensor Module

KY-015 Arduino temperature and humidity sensor module, provides a digital serial interface to measure humidity and temperature.

This module consist of a DHT11 digital humidity and temperature sensor and a 1 kOhm resistor. The DHT11 uses an internal thermistor and a capacitive humidity sensor to determine environment conditions, an internal chip is responsible for converting readings to a serial digital signal.
