Automatic Smart Plant Watering Kit

The Smart Watering Kit allows to provide all your own smart plant monitoring system with ease of use and unlimited options! The kit include pump, soil moisture sensors, water switch to redirect the water to up to 4 plants and pipes for the water to go through.

How to make it?

1、Circuit diagram design

①、The MCU I used ATMEGA32U4-XUAU Minimal circuit system,Similar to the use of atmega328p chip, they are all programmed in the ARDUINO IDE environment.

②、RTC timing module I choice DS1307,I2C Address is 0x68.

③、ESP8266 IoT control

Internet of things control module, in order to facilitate my wireless monitoring of watering at home.

④、Relay control module

We use a 12v motor to water the flowers, and the drive capability of the ATMEAG32U4 chip is not enough, so we need to use an additional power supply to supply power, so we need to use a relay drive circuit to control the 12v servo.

⑤、12v motor interface

⑥、Voltage detection

Through ADC analog-to-digital conversion, to detect the size of the input voltage to ensure safety.

⑦、PCB design
