Initial Setup.

For this project you will need:

  • A raspberry pi running raspbian buster lite
  • A DS18B20 temperature sensor
  • A breadboard
  • Jumper leads
  • 4.7k Resistor

Wiring.

Note: this should be done while the pi is switched off

Look at "Wiring.png" and copy diagram

Setup (Code).

To setup this project, follow these commands in terminal

Before you can use any 1-wire devices, you must first tell the Raspberry Pi how to read them.

Type:

sudo nano /boot/config.txt

And then add the line to the bottom of the file (if it is already there you can skip this step):

dtoverlay=w1-gpio

Now press "CTRL+X" followed by "Y" and then "Enter" Now reboot:

sudo reboot

Once the pi has rebooted, clone the repo:

git clone https://github.com/realdeadbeef/internet-thermometer-using-raspi-and-thingspeak.git

Install pip3:

sudo apt install python3-pip

Install httplib2

sudo pip3 install httplib2

Install urllib3

sudo pip3 install urllib3

Running the script.

Type:

sudo nano internet-thermometer-using-raspi-and-thingspeak/code.py

And look for the line: key = "ABCEDFG1234567" # Put your API Key here And replace ABCEDFG1234567 with your API key.

Now press "CTRL+X" followed by "Y" and then "Enter"

And then to run the script:

python internet-thermometer-using-raspi-and-thingspeak/code.py
