NOTE: I will be using a DHT11 temperature sensor to produce data on the Arduino end. Since this is a tutorial on reading data from the serial port using Python, not Arduino, I recommend visiting a DHT11 tutorial to learn how to print temperature data from the sensor to the serial port (see here, or here). Serial communication is preferred since no of wires used is less, reduces the cost of distance communication.In this post, serial communication using python programming is explained. Since Serial Communication is to be established between two devices, Arduino is used as another device in this post.
