Make a unique digital thermometer using Arduino.
Hope everyone is very much better. It’s very happy today. Because today we are going to make a professional project in Arduino first. Before that we’ve finished about 15 episodes, just about the different functions of the Arduino. Today’s gift is for those who have watched these episodes. Today we will learn how to create a digital thermometer using Arduino. I have already said those who did not see the earlier tutorials, please do not see today’s tutorials, please do not see today’s tutorial. Because today’s tutorial will be a combination of some of the previous tutorials. So today I do not have many issues in detail because I have already explained them in detail. Well, we did not talk and entered the main discussion.
Necessary equipment:
Arduino Board 1
1 LM35 Temperature Sensor
1 2 Digit Seven Segment Display
Some of her and some other tools are available
How does the digital thermometer work?
To make a digital thermometer, first we need to know how it works. I always say that if you do not work, you will first know about its mechanisms. Because no matter what can be learned by memorizing. When you can make mechanisms, you can create interesting fun projects with it yourself.
We will use a sensor on our thermometer. One feature of this sensor is that this sensor gives a voltage output based on temperature. According to the Datasheet, this sensor gives 10 ml volt output for every 1 degree Celsius temperature. Now suppose our room temperature is 30 degrees Celsius. So how many millig volts we get in this sensor output? Simple answer, 10 x 30 = 300 ml voltage. Now we do not see this voltage or we can not measure it with multimeter all day long. What to do? Do you remember? Since the sensor output voltage is less than 0 volts and less than 5 volts, we can take it in an adrenaline using its voltage analog input function. Let’s say 1 volt = 1000 ml volts. What can we do? If the sensor output pin is connected to the analog input pins of the Arduino, then we can calculate the output voltage of the sensor in the Arduino. Suppose we received the voltage in the Arduino and found that 300 millimeters volt output is available here. Now we already know 10 ml volt output for 1 degree Celsius temperature comes. If you get 300 ml volt output then how much temperature will be? If you count, the answer will come 30. That means we can also do the work of measuring the temperature in Arduino. Now the only job is to show the result. We have already learned how to use the Seven Segment display. If we could just show the results in Seven Segment display then our Digital Thermometer This is the story of making a digital thermometer.
What was afraid? End this little writing? Not at all. My original video is there. The purpose of tuning is to get a good idea about the tutorial in the story before you watch the video. So let’s go and watch the video by saying no.
