Raspberry Pi IoT Server Tutorial: InfluxDB, MQTT, Grafana, Node-RED & Docker

Рет қаралды 211,259

Күн бұрын

This tutorial will create an internet of things server on your Raspberry Pi. This server will use Mosquitto MQTT, InfluxDB, Node-RED, Graphana in docker containers. We will use the helpful IoTStack tool which will configure our docker containers for us. This tutorial will allow you to collect any kind of sensor data you like, send it over your network to this raspberry pi server and visualise it on a Grafana dashboard.
This system consists of a series of sensor nodes that send sensor data in a JSON message over the network to a Raspberry Pi via MQTT. MQTT is a network protocol where a client pushes data to a broker, such as mosquitto, and the broker pushes that data to any client that has subscribed to that topic. A topic categorises the data that is sent. Any client that is subscribed to home slash sensor will be forwarded this MQTT message. NodeRED will subscribe to this topic, interpret the json message data and then send the data to a database to be stored and used. InfluxDB will store all the sensor data. Then a Graphana front end will query the database in order to display the data we want to see and do a whole host of other things.

The point is that viewing grafana i only see that data comes from sensor_data which is the db name from influxdb.

Wow. You are doing what I have been reading so many tutorials to try to do. I am setting this up to remotely monitor a vacation property. I am looking at setting up a sensor that will measure the distance to the surface of water in a sump pit. I was wondering if you could provide some guidance on this. I was thinking of using a HC-SR04 to monitor the distance to the surface of the water. Wondering if you have any thoughts on this.

@toastedregret1601 Жыл бұрын

HC-SR04 is probably the best pre-built option - there aren't any real water level sensors out there that are bigger than a few inches. However, ultrasonic distance sensors are relatively sensitive, meaning a slight off-angle or shaking it could ruin the distance it computes. I'd recommend looking into creating your own water-level sensor, which would be the most-reliable long-term. I'm pretty sure one can be built with the right spare parts.

@mediaicon8774 Жыл бұрын

@@toastedregret1601 Thanks. I am thinking of mounting it to a piece of angle bar to make sure it is not moving. I have seen diy sensors that use conductance through screws and bolts. Just not sure how accurate that is going to be. I am currious how I would calibrate it outside of submersion. I also don't know that ground water with all the 'impurities' would have the same kind of conductance to get a feel for depth of the water level. Are you suggesting something different with an ultrasonic diy? Thanks.again.

@toastedregret1601 4 ай бұрын

@@mediaicon8774 I've used the ultrasonic distance sensors quite a bit for different projects, and they are pretty great to measure distances up to several feet, as long as you can get the transmission portion of the sensor mounted on something that would keep it from moving around. The sensor's face should ideally be as parallel as possible to the surface you're trying to get a reading on. Conductance is an alternative but the drawback is it may require calibration if exposed to liquids for a long period of time. It's probably worth trying an ultrasonic sensor and see if it suits your needs.

It happens that the WiFi library has its init method as private method, so no way you can start the WiFi in AP+STA mode (at least, I've not been able ot do it). Is there any work around.

I've been trying to get a similar setup but using CasaOS instead of IOTStack (but resorting to IOTStack for hints about how to set up Mosquitto and Influxdb which are not in the CasaOS app store). This gives a nice web front end to the various web apps and easy remote file access. Was wondering if anyone knew of a web app for Mosquitto, something that would allow web page monitoring of message traffic (similar to MQTTX, but web) and maybe some configuration GUI avoiding all the command line and config file editing jugitsu, similar to what Portainer does for Docker. Likewise for InfluxDB. I am very confused about what URL to use for one container from within another. What are the (different) URLs listed in Portainer for each container for? I found using the specific URL for the Mosquitto container worked in some cases where the URL of the Pi did not.

You can SSH into the raspberry pi similar to a virtual machine. There are tutorials online on how to do it. It's sometimes referred to as "headless mode". You can also take it a step further and access the raspberry pi from anywhere in the world by exposing its port on the router. That's a huge security risk though - you can also alternatively use an application like VNCViewer, set the raspberry pi address as static so it doesn't change on startup, and access the raspberry pi via VNCViewer from ideally anywhere.
