Hydros to Control Ikea Greenhouse Cabinet?

[AndrewT]

Has anyone thought of using the Hydros Universe to power/control a small greenhouse cabinet? I know this has been done before using Arduino/Raspberry-Pi, but I am already in the Hydros universe and love the software interface. I know this is likely the more expensive method and I am utilizing the software for unintended purposes.

I am still in the planning/testing stages - Any thoughts or recommendations are appreciated! I know I will likely need 2 sets of 0-10 Inputs/Outputs based on everything I am wanting to monitor/control.

Smart Ikea Greenhouse using Hydros

Idea: Control environment in greenhouse cabinet and water plants when needed

Method – monitor environmental variables (air temp and humidity, humidifier water level, soil moisture sensors); control watering of plants and refilling of humidifier water when needed

Monitoring –

• air temp and humidity using DFR0588
  • Gravity: Analog SHT30 Temperature & Humidity Sensor - DFRobot
• soil moisture % for each plant using sensor linked below and 0-10v Input
  • Soil Moisture Sensor: https://www.amazon.com/dp/B08BC5533...olid=2L4OVCKC2G9M2&psc=1&ref_=lv_ov_lig_dp_it
• Humidifier water level using optical or float water level sensor
• ATO Water Level using optical or float water level sensor

Control –

• Water plants using peristaltic pumps controlled by OONO Power Relay and 0-10v Output on Hydros (watering would be based on soil moisture sensor values)
  • OONO Relay: https://www.amazon.com/dp/B08BNJMNX...olid=2L4OVCKC2G9M2&psc=1&ref_=lv_ov_lig_dp_it
  • KAMOER Pump: https://www.amazon.com/dp/B07GWJ78FN?psc=1&ref=ppx_yo2ov_dt_b_product_details
• Hydros RODI Solenoid to Refill ATO container (peristaltic pumps for plants and ATO pump that fills humidifier will draw from this chamber)
• Lights – 12v LED Full-spectrum, ideally using 0-10v to PWM converter to control light intensity using 0-10v output of hydros.
• Control 12v air circulation fan, based on time of day and humidity level

Thoughts, comments, ideas, and recommendations are appreciated. J

Update: I received the 0-10v soil moisture sensor today and have it hooked up to the hydros.
0-10v = 0% to 100% soil moisture level; currently reading at ~20% and cheap backup moisture sensor reading as ~4 (high moisture) - (which seems reasonable; soil is very wet to the touch).

Thinking of using an LED driver like this one:

https://www.amazon.com/mirrea-100V-227V-Transformer-Compatible-Potentiometer/dp/B0B3JDQ1XD/ref=sr_1_3?crid=13F7Q16Q74Z6I&keywords=led+24v+0-10v+dimmable+driver&qid=1666644615&sprefix=led+24v+0-10v+dimmable+driver%2Caps%2C245&sr=8-3

Input: AC 100V-227V 0.5A
Output: DC 24V 2.5A 60W
and it accepts 0-10v to control PWM dimming.

On a light fixture like this:

I confirmed with the manufacturer that this light fixture will work with an inline PWM dimmer.

You may want to check out Reef and Reptile Automation on YouTube. He uses Hydros with his Reptiles which sounds similar.
