I tried installing the library (not really sure where to store it than) but that didn't help either. Therefore I need the import serial (or import pyserial, I tried both) this doesn't work. Among them, you can communicate through serial port with PySerial library. For a project, I need Phyton to read my Data from my arduino-uno. Python has a great asset, it’s that you have a package for almost everything.
IMPORT SERIAL LIBRARY IN ARDUINO HOW TO
Now, let’s see how to deal with that on the computer side. After downloading the program to Arduino, the serial monitor should tell us everything. If the IDE is asking to install a third-party library (Adafruit Unified Sensor Lib), it’s normal, just accept.Īs a base, you can use the example given for this library called “ DHTTester” in the File -> Examples sub-menu.Įverything is already well commented, but don’t forget to change the DHTPIN to 4 (according to the scheme above) and uncomment the DHT11 type. We can install the “DHT sensor library” by Adafruit: With your Arduino IDE, let’s install some additional library: There is one setup left where the wire order can be different according to your PCB. Note: You should pay attention to the wiring according to the small pin’s description. If you don’t have it, it should still working. Wiring For the PCBless version, it’s recommended to use a 4.7kΩ resistor on the data line. Note: like it’s very slow, the delay between 2 data acquisition should not be under 2 seconds, otherwise, you will receive nothing because the chip won’t stop processing the data. You can find out more with the DHT11 datasheet or here. There is a chip inside that does the analog to digital conversion and returns a digital signal with the temperature and humidity. This sensor is very basic and slow, but is perfect for some basic data logging.

In this context, I will use as example a DHT11 sensor with an Arduino Uno to retrieve data back. You can send raw strings, use a protocol or even create your own.

I always wanted to find an efficient way to share information between an Arduino and a computer.
