Hi, my name is Yousef, I’m the founder of ONAXYZ, and OMK2 is my innovation!
OMK2 is an automation system I put together to feature:
- Autonomous and precise pH control (using stepper motor driven peristaltic pumps)
- Autonomous and precise nutrient dosing (using stepper motor driven peristaltic pumps)
- Autonomous temperature and humidity monitoring and regulation
- Automatic light emission cycle
- Automatic watering/misting
- Autonomous CO2 monitoring and dosing
- Autonomous water level monitoring, flush, top off, and refill
- Remote monitoring and control

- [master] One Raspberry Pi 3 Model B running NodeRED + Dashboard
- [slaves] Several NodeMCU Lua’s (for sensors and control of peripherals)
- Kamoer stepper motor peristaltic pumps paired with TB6600 drivers
- HomeLab pH meter
- DFRobot EC meter
The GUI is hosted on a local WiFi network and all devices use to communicate with each other.
*OMK2 is a work in progress and some of the mentioned features are still in development. Namely the autonomous CO2 monitoring and dosing, autonomous temperature and humidity regulation, autonomous water level monitoring + flush + refill, remote monitoring and control.
