Re: Liquid volume sensor in a tank

I'm slightly late to this conversation, but I was happy with the ease of setup of the JSN-SR04T with the Pi. I opted for it over the HC-SR04 because of the environment it was going to be used in (like yourself, it was to measure the heigtht of water in a water tank). The how-to for the project is he...

Re: RPI4 (4GB) and Grafana

I've had good success installing Prometheus and Grafana onto a Pi 4. However, I went about it by downloading the standalone binary files and installing that way. I was plesantly surprised by how easy it was. I have a full write up here - https://leanpub.com/rpcmonitor/read

Re: Straightforward / bulletproof temperature logger

I built a project using multiple DS18B20's to monitor different temperatures on a solar water system. Instructions here - https://leanpub.com/rpctemp/read It includes writing up a graph using d3.js to present the data locally. The implementation isn't overy complicated, but there are a few different...

Re: Reading Live Sensor Data Flask & Raspberry Pi

It's a good question about integtration of Grafana into an already established site (That is what I am presuming you were interested in). While I don't know the answer to that question, might I suggest that you check out the how-to(ish) that I wrote that explains the setup of Prometheus and Grafana ...

Re: Plotting real time graph

I might be a little late to the party, but I put together an ultrasonic distance measuring project using a JSN-SR04T a couple of years ago and accompanied it with a d3.js generated graph. I wrote up the instructions which you can check out here - https://leanpub.com/rpcultra/read. However, if you wa...
