Hello! When I started out I was using Atlas / Whitebox carrier boards but I have since designed my own board and no longer need to use these. I was thinking some of you might be interested in purchasing mine. Below is s a list of carrier boards I have. If you are interested please send me a message ...

I found a good video on Youtube that describes how to identify the proper soil sensor (there are many counterfit boards) and how to fix the issue you are experiencing:

Good luck!

While the Tentacle T3 carrier board was made for the Raspberry Pi it is just using I2C so you can connect it to an ESP32 dev board instead. To accomplish that you will need to: Wire 3.3V power to PIN 1 of the header to 3.3V on your ESP dev board. Wire 5v to PIN 1 of the header to the 5V on your ESP ...

I'll defiantly look into MLX90614 IR sensor. Looks like winner, thanks!

Please keep us posted. I am very interested in your project!

Do you have the ability to control the pumps in both directions? If so, an option might be to stop trying to keep prime (liquid in the line) and instead after each use of the pump you could reverse the flow so you are always starting from a known state (no liquid in the line). This way you can progr...

I've been wanting to setup my system to optimize for VPD but I have no way to automatically to determine the leaf temperature. Does anyone know how the leaf temp can be detected?

If you are going to use home assistant then any Pi can handle that. Although, likely your system will grow more complex from there. The Pi is good at providing the web server and running home assistant for data collection but there is no magic box to plug the Pi into to completely monitor a hydropon...

For measuring the amount of water in a tank I would suggest using an ultrasonic sensor instead of relying on flow meters. They are more accurate and cheaper. You can use these for height sensors and from that you can calculate the current volume of your tank. For dosing it depends on what type of fe...

Hello,

Does this work without an AC Snubber circuit? I have found without it inductive loads cause arcs through the relay that over time (3 or 4 uses from my observations) that cause the relay to fail open (powered on). I assume the compressor on the AC would be an inductive load.
