Background story: Once upon a time, TJR was a freshman in high school. The school was near a mountain and there was a large open space. One day, the leader had a sudden idea to engage in labor education and let TJR and his classmates grow vegetables. TJR saw that the ground was very dry and needed frequent watering, so he wanted to build an automatic irrigation system, so he came up with this project.

The program has passed the test, and the library files and source code are attached. This open source project is only the main control board part of the entire system. Misaka No. 0x1BF52 is responsible for programming, and TJR2005 is responsible for hardware assembly (so TJR is the one who pays the most). Continuously updated.

Peripherals (for reference only)

1. Power amplifier module with music chip
2. soil moisture module
3. DHT11 temperature and humidity probe
4. Large capacity battery
5. High power solar power panels

Function

1. Soil moisture is detected every 30 minutes. When the number of probes reaching the humidity threshold is greater than or equal to the minimum number of probes to start watering, the watering program is started.
2. Before watering, a sound will be played to warn people around you to stay away.
3. When the watering time reaches the length of a single watering, watering will automatically stop
4. If you stay on a non-main page (time page) for a long time without any operation, you will automatically switch to the main page.
5. If there is no operation for a long time, the digital tube will automatically turn off (press the menu button to wake up)

Time setting method

1. Before powering on, press and hold the setting button until the system self-test is completed (relays, etc. are turned off) and then let go.
2. Enter the hour setting page and press the plus key to increase the hour.
3. Press the setting key to enter the minute setting page, press the plus key to increase the minute
4. Press the Set button to enter the save page, and press the Add button to save the time setting.
