I am working on recreating the automated Hydroponic system, it was too cool to not try, and ran into some issues with the wiring.
In the full system circuit diagram I don't see the flow meter included for example. If anyone has a working system, could you please provide a few pictures of all of the wiring to help me out.
Thanks.
Are you using the Atlas Scientific dosing pumps? The reason I'm asking is that I'm working on a hydroponic system myself but, I had to go with the less expensive generic peristaltic pumps (I saw that Mycodo supports these as well). So, I need help wiring my RPi 4, SainSmart 8 channel relay, 12V external power supply, and two 12V generic dosing pumps. If anyone out there has any info they can point me to, I'd appreciate it greatly!!
Thanks for taking the time to comment. I hope you get a response to your flow meter wiring question.
The Atlas Scientific flow meter should be changed to I2C mode (per the manual), then you can connect the SDA and SCL pins to the I2C lines. Then just apply power, add the Atlas Scientific flow meter Input in Mycodo, activate the Input, and you should start to get flow data if water is flowing.
