Include ethercard h ethernet interface mac address must be unique on the lan.
Arduino temperature and humidity sensor code.
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.
It measures both moisture and air temperature.
Dht11 humidity temperature sensor.
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.
The materials are here as follows.
They are similar to each other.
Display humidity and temperature on the serial monitor.
The dht11 temperature and humidity sensor senses measures and regularly reports the relative humidity in the air.
Dht11 sensor is used to measure the temperature and humidity.
In this project we will use the ky 015 arduino dht11 temperature humidity sensor and display it to the arduino ide serial monitor.
I am using arduino huzzah feather for sht85 sensor.
10k ohm pull up resistor.
It has a resistive humidity sensing component and a negative temperature coefficient ntc.
Temperature and humidity readings are measured by the help of arduino uno and dht11 sensor.
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.
Work fine dht code from.
An 8 bit mcu is also connected in it which is responsible for its fast response.
Example testing sketch for various dht humidity temperature sensors written by ladyada public domain.
Dht11 digital temperature humidity sensor delivers temperatures between 0 c and 50 c and humidity between 0 to 100.
This project is really simple and shouldn t take us very long.
The warmer the air is the more moisture it can hold so relative humidity changes with fluctuations in the temperature.
The temperature accuracy is 2 c maximum.
For instance i used a0 so you need to connect the sensor to the analog pin a0.
Include dht h dht dht.
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.
The code that i have written records the temperature and humidity for all 3 sensors after every 3 seconds.
How to use the dht11 temperature and humidity sensor with an arduino.
Arduino reads the temperature and humidity at 2 second interval and sends to the serial port.
Arduino uno any uno will work i have a geekcreit uno.
