Sprout is a Modern Indoor Planter which automatically waters your plants, herbs, vegetables, etc and will revolutionize your gardening game.
The optional Bluetooth feature can be used to manually toggle & control the water pump wirelessly from your smartphone.
Develop: Are you a programmer, engineer or designer who has a great idea for a new feature/design in Sprout? Maybe you're just a beginner or you've spotted a bug? Feel free to grab our code, schematics, 3D design files & laser cutting files from Github and tinker with it.
Electronic Components Required:
1x Arduino Nano/ Arduino Pro Mini
1x DC Water Pump 12V or 9V
1x Soil Moisture Sensor
1x LM7805 Voltage Regulator
1x IRF540 MOSFET
1x 220 Ohm Resistor
1x IN4001 Diode
1x Header Pins Strip
1x 2-Pin Screw Terminal
1x DC Power Jack (Male + Female)
Optional: 1x HC-05 Bluetooth Module
The 7805 regulates the supply voltage and reduces it to a constant 5V making it suitable to run the Arduino & Soil Moisture Sensor.
The MOSFET acts as a switch which is controlled by the Arduino. We use the MOSFET since the Arduino cannot directly power the DC Pump. The resistor connected to the gate of the MOSFET prevents the MOSFET from getting damaged. The flyback diode connected across the pump provides a path for dissipation of stored energy when the pump is switched off.
Moisture Sensor The sensor feeds an analog value to the Arduino. The threshold level of moisture is calibrated by the user depending on the type of plant used and the typical h
Uses Serial Communication to transfer data between the Arduino and your Smartphone.
A 1x Scale printable PCB as well as the board view and schematic is available in the GitHub repository.
The repository also contains an A4 size PDF which contains multiple PCB's on a single page. This can be used to make multiple PCB's at a time for mass production
