![]() ![]() In the new file we will write the following, replace examples with your own details: ![]() Open up a plain text editor, save the file under a name of your choice using the filetype suffix. We're going to write a Python script to send the incoming serial message to the OpenSensors message broker. You should see data coming in from the sensor. Press the Upload button and let it do it's thing. Plug your Arduino in to your Raspberry Pi or PC. Feel free to change the messages sent out by the sensor to something more suited to you. You now need to load up the Arduino code for this project, from here.Ĭopy and paste this code into your Arduino IDE. If it is greyed out, simply run Arduino IDE from CLI as superuser: Run the Arduino IDE, check under Tools that the serial monitor isn't greyed out. On the image below, the left pin & wire correspond to Pin2 on the Arduino, the central pin & wire to Ground (GND) and the right to 5V on the Arduino board. The Motion Sensor will have three pins, some PIR sensors omit the labelling besides these pins, in that case, the pins correspond to Pin2, GND, 5V. Sudo apt-get update & sudo apt-get install arduino arduino-core Lastly, you will need to install the Arduino IDE: You will also need a user account on OpenSensors.io, which is the IoT messaging platform we'll be using. However, if you don't already have Python installed you will need to run the following command: You will need to install Mosquitto Python module, Paho MQTT client, simply type the following into CLI (Command Line):
