Arduino library for the K-Nearest Neighbors algorithm. We can also load Node-Red on Raspberry Pi data collection nodes, and have them publish data to a central Node-Red server.Arduino library providing a simple interface to perform checksum calculations utilizing the CRC-32 algorithm. The Mosca MQTT server component allows for a simple standalone architecture to connect wireless Arduino modules into a Node-Red IoT solution. Below is a example of what you should see. To access the web dashboard enter: 1880/ui. To compile and view the Node-Red application, click on the Deploy button on the right side of the menu bar. The Web dashboards offer a number of different components that could be used for this example I used a gauge and a text node. The Arduino topics are defined in Node-Red by double-clicking on the mqtt node and then define the topic to match the Arduino topic.Īfter the MQTT connections are configured Web dashboards can present the final data. To connect the Arduino module to Node-Red mqtt inputs are added to the project.

Or the component can be install within the Node-Red web interface by selecting the “manage palette” option, and then search for mosca.Īfter Mosca is installed, all that is required is that a “mosca” node needs to be dragged and dropped into the Node-Red project.

The Mosca Node-Red component can be either installed at the command line by: cd $HOME/.node-red Mosca is a standalone MQTT server that can be installed directly into Node-Red. There are a number of free internet MQTT servers () that can be used or an MQTT server can be loaded directly on a local server (i.e. I’ve had good results running Node-Red on a very old low end laptop running Xubuntu, (see steps 1-3 in this linked guide).

If you don’t have a Raspberry Pi you can install Node-Red on Window, Mac OS or Linux systems. The base Node-Red installation includes MQTT interfacing components but it does not include an MQTT server. Node-Red is a simple tool to create your own Internet of Things applications. Node-Red is an excellent visual programming environment that is part of the Raspberry Pi base install.

For this example we define the topic humidity to show the moisture sensor value, and msgtext to show the message (‘Needs Water’ or ‘).īelow is our sample Arduino code for passing the moisture data to our MQTT server. The nice thing about MQTT is that you can define topics for each of your data points.

When voltage is applied long term to moisture sensors ionization in the soil will cause a combination of false reading and deterioration of the sensor plates. Our Arduino plant moisture setup is good for testing but not a good long term solution. Some sensors also include a digital output with a potentiometer to adjust the digital 0-1 moisture limit. The basic moisture sensor has 3 inputs VCC, GND, and AO. Moisture sensors are very low cost and they start at about $2. Our goal was to get the MQTT technologies working, with some moisture inputs (and not a final plant monitoring system). We then setup an MQTT server on our Node-Red Raspberry Pi with a web dashboard.

Plant Moisture Monitoring MQTT Exampleįor our example we wanted to do a simple plant moisture example that used a solar charger and an Arduino Wemos module. MQTT (Message Queue Telemetry Transport) is becoming one of the standards for this and it is pre-installed with Node-Red. To connect the Arduino modules to PCs, Raspberry Pi’s or Linux nodes that are a number of communication choices. These modules allow you to do some interesting IoT (Internet of Things) projects. There are some great Arduino modules with integrated ESP-8266 wireless chips, some of the more popular modules are:
