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

Comments
I especially like the connector for ESP-01. Remote access is super convenient.
It would be even cooler if the connections and the bootloader were modified as to allow remote sketch upload (via the hardware UART and ESP8266)! For example, using ESP-Link firmware.
