Arduino uno any uno will work i have a geekcreit uno.
Arduino temperature and humidity sensor code.
The code that i have written records the temperature and humidity for all 3 sensors after every 3 seconds.
The dht11 data pin is connected with arduino digital io pin.
Dht11 and dht22 are sensors that we can use to measure temperature and humidity.
You can choose one of them depending on your needs if you only want to get temperature we recommend using a waterproof ds18b20 temperature sensor instead.
In this project we will use the ky 015 arduino dht11 temperature humidity sensor and display it to the arduino ide serial monitor.
An 8 bit mcu is also connected in it which is responsible for its fast response.
Arduino reads the temperature and humidity at 2 second interval and sends to the serial port.
Temperature and humidity readings are measured by the help of arduino uno and dht11 sensor.
Include ethercard h ethernet interface mac address must be unique on the lan.
Work fine dht code from.
Dht11 sensor is used to measure the temperature and humidity.
The dht11 temperature and humidity sensor senses measures and regularly reports the relative humidity in the air.
10k ohm pull up resistor.
Dht11 humidity temperature sensor.
I have three such sensors connected to the huzzah with the adafruit tca 9548a multiplexer.
Dht11 digital temperature humidity sensor delivers temperatures between 0 c and 50 c and humidity between 0 to 100.
I am using arduino huzzah feather for sht85 sensor.
Before you can use the dht11 on the arduino you ll need to install the dhtlib library it has all the functions needed to get the humidity and temperature readings from the sensor.
It is very inexpensive but it gives values of both temperature and humidity at a time.
They are similar to each other.
Include dht h dht dht.
Example testing sketch for various dht humidity temperature sensors written by ladyada public domain.
The temperature accuracy is 2 c maximum.
Try changing the analog pin for the sensor in the code or unplug the sensor and plug it back into the analog pin that is used in the code.
How to use the dht11 temperature and humidity sensor with an arduino.
Hi use below code and usage the default dht h from arduino libraries.
It has a resistive humidity sensing component and a negative temperature coefficient ntc.
It measures both moisture and air temperature.
The materials are here as follows.
This project is really simple and shouldn t take us very long.
