Summary:

1. Design of automatic and intelligent flower watering system based on 51 single chip microcomputer

This design consists of STC89C52 single-chip circuit + 4-bit common anode digital tube display circuit + ADC0832 sampling circuit + water pump control circuit + soil moisture sensor circuit + button circuit + power circuit.

1. The digital tube displays the humidity measured by the soil humidity sensor in real time.

2. Key description: from the first one on the left, the minus key, the plus key, and the setting key. You can use the keys to set the upper and lower limits of humidity.

3. When the humidity is lower than the lower limit, the water pump will be automatically turned on for automatic irrigation. When the humidity is higher than the upper limit, the water pump will be disconnected to stop irrigation.

4. With manual mode, press the minus key to manually turn on the water pump, and press the plus key to manually turn off the water pump.
