Arduino Coding Arduino Pulsein Arduino PulseIn:How to Measure input signal periods using an Arduino. There are two Pulse-In functions. Which one you should use for best accuracy? Find out why there two functions, why interrupts must be on for one and off for the other, and why your measure...
Before you can use the DHT11 on the Arduino, you’ll need to install theDHTLib library. It has all the functions needed to get the humidity and temperature readings from the sensor. It’s easy to install, just download the DHTLib.zip file below and open up the Arduino IDE. Then go ...
We have another tutorial on the DHT11 for theArduinothat goes into detail on relative humidity and how the DHT11 measures it. So instead of repeating all of that here, check outHow to Set Up the DHT11 Humidity Sensor on an Arduino, then come back for the specifics on setting it up o...
Color sensors can detect and measure the visible color of an object. They typically use an array of photodiodes or phototransistors to sense the intensity of red, green, and blue light reflected or transmitted by an object. By analyzing the RGB (red, green, blue) values, the sensor outputs...
Then solder it again to the PCB of the charger (third picture). Check if the battery and the Arduino fits into the case. The result should look like on the most right picture. Step 14: Prepare DHT22 sensor Cut off the upper part of the DTH22 sensor if you like. You could use the...
Formula computes real time AH with DHT22 sensor on single board computer June 2017: Single board computers provide low-cost solutions to automation and testing. On element14.com a BeagleBone Black Wireless equipped with a DHT22 RH&T sensor has been used to monitor outdoor and indoor temperatur...

I am trying to finish this project as my thesis but after a month trying different ways to solve it, I really don’t know what else to do now. I am building my app with App inventor 2 and with my arduino. I have a gas sensor which via bluetooth sends the numbers to the app and...
You can use thepulseIn()function in the Arduino code to read the length of the pulse from the Echo pin. After that, you can use the formula mentioned above to calculate the distance between the sensor and the object. HC-SR04 Specifications ...
Arduino DS18B20 Sensor Project In one of our previous tutorials, we have shown you how you caninterface LM35 Temperature Sensor with Arduinobecause it's cheap, easy to use, and requires minuscule power for stable operation. But one of the major disadvantages of the LM35 sensor is that it is...
