Plant Tower - Hydroponic Tower

This planter is designed to support the growth of vegetables in a hydrophonic system within your own home. The system irrigates and waters the plants in a vertical structure. The plants, e.g. tomatoes, lettuce, peppers or spring onions, are planted in growing pots and hydrophonic granulate.

The control system consists of an esp8266 microcontroller (Wemos D1 mini) with Internet access. The times for switching the LEDs on and off, their brightness (PWM) and the amount of water to be pumped are stored in a database.

The power supply consists of a 12V power supply unit and a step-down converter to 5V for the microcontroller. The 12V are connected to the motor drivers and mosfets of the LED strips.

The LED strips are controlled by the microcontroller via a mosfed breakout board.

A peristaltic pump in each tower draws water from a water reservoir. A non-return valve is installed after the pump in the lower area of the tower so that no water can flow back into the tower above. A Y-piece then divides the hose. This Y piece also reduces the diameter. Both outlets of this part are again subdivided with Y pieces, so that 4 hose ends are left. These hose ends are fitted with hose reducers and small holes so that pressure can build up during pumping and water is pumped from all 4 ends.

PE pressure pipes are located in the middle of the towers for structural support. The electronic wires run inside the pipes up to the LEDs.
The two lower parts are connected by 2x M3 screws and 2x press-fit sleeves. Both parts fix the remaining part of the tower with a wooden plate.

Sensors for environmental values such as temperature, humidity and pressure can be connected to the microcontroller. An ultrasonic distance meter should be able to measure the water level in the water reservoir.

All parts were printed with PLA, some with support.
You also should check the food compatibility of all parts.
