![]() ![]() Check if any reads failed and exit early (to try again). Initialize DHT sensor for normal 16mhz Arduino #define DHTPIN 2 // what pin we're connected to Written by ladyada modified by Rui Santos Example testing sketch for various DHT humidity/temperature sensors Go to Files / Examples / DHT_SENSOR_LIB / DHT Tester.Rename the extracted folder and remove the “-“. Otherwise your Arduino IDE won’t recognize your library.Here’s the code you need for this project: Here’s how to connect the DHT11 to an Arduino: You can use the preceding links or go directly to /tools to find all the parts for your projects at the best price! Arduino UNO – read Best Arduino Starter Kits.You need the following components to make this circuit: #Serial plotter arduino ide alternative serial#To test the Serial Plotter tool I’m going to build a simple circuit that measures the temperature with the DHT11 sensor. Arduino with DHT11 Temperature and Humidity Sensor In order to use the Serial Plotter tool you need to download the latest version of the Arduino IDE, at the time I’m writing this blog post is version 1.6.6. println() command with a new value .ĭownload the Arduino IDE version 1.6.6 or above This means that the plot is updated every time you use the Serial. The X axis has 500 points and each tick of the axis is equal to an executed Serial.println() command. The vertical Y axis adjusts as the value of your serial data increases or decreases. The Arduino Serial Plotter is a Tool that comes pre-installed with your Arduino IDE (version 1.6.6 and above) that takes incoming serial data and displays them in a plot. Download Free Arduino eBook with 18+ Projects.Complete Guide for DHT11/DHT22 Humidity and Temperature Sensor With Arduino.This tools gives you the ability to visualize your data in a plot that is updated in real time.īefore you continue reading this project, I recommend reading the following tutorials: The latest release of the Arduino IDE 1.6.6 comes with a new tool called Serial Plotter. ![]()
