Anyone with a backyard pool will know that if you relax a little, the whole thing will turn green. For those tired of having to master everything, the idea of automated pool care may be attractive. The project from [the cautious mayor] hopes to do this.
In order to facilitate analysis using grafana, the data are plotted into charts.
The project uses Ti simplelink wireless microcontroller to run the program, which allows data to be unloaded to the base station for mapping with grafana. The system can monitor the pH level and ORP (oxidation / reduction potential) level using a probe connected through the BNC connector. Based on these readings, the unit can inject chlorine into the tank as needed using a peristaltic pump driven by Ti drv8426 stepper motor driver.
We hope to pay close attention to this system for a period of time to ensure that it does not use too much or too little chemicals in the swimming pool. However, this is easy to do when all data is neatly recorded in a web accessible graph.
We have also seen other hackers exercise similar control over their own pools. If you have been working on your own home automation project, be sure to write to us.
