Lesson 12 DHT11 Temperature and Humidity Sensor
Overview
In this tutorial we will learn how to use a DHT11 Temperature and Humidity Sensor.
It’s accurate enough for most projects that need to keep track of humidity and
temperature readings.
Again we will be using a Library specifically designed for these sensors that will make
our code short and easy to write.
Component Required:
(1) x Elegoo Mega2560 R3
(1) x DHT11 Temperature and Humidity module
(3) x F-M wires (Female to Male DuPont wires)
Component Introduction
Temp and humidity sensor:
DHT11 digital temperature and humidity sensor is a composite Sensor which
contains a calibrated digital signal output of the temperature and humidity. The
dedicated digital modules collection technology and the temperature and humidity
sensing technology are applied to ensure that the product has high reliability and
