Smart Automatic Flower Watering System DIY Science Experimental Tool Kit with R3 Development Board for Learning

The smart watering system device uses the R3 development board as the main control board. Equipped with a dedicated expansion board and PH2.0 sensor to avoid messy wire connections, build projects more easily and quickly, assembly and wiring are relatively simple, and performance is more stable! Production type:manual assembly, screw fastening structure Compatible development board:for development board Power supply method: 1. Use TYPE-CUSB port power supply voltage (5V); 2. Use power supply voltage (DC7V-12V) Others: onboard custom function button x1, spare expansion interface x1. Supported programming software:for ArduinolDE, for Mixly, for Ardublock, for Scratch. This kit can achieve: 1. The D2 button switches between automatic mode and manual mode. 2. The LED light is used as an indicator light for the working status of the water pump. 3. Manually control the water pump for watering. 4. The soil moisture sensor controls the switch of the water pump. 5. The water level sensor is used to detect the remaining water volume. When the water level is too low, a water shortage warning is issued through a buzzer and pumping is stopped. 6. The LCD display shows the real-time monitoring values of soil moisture and water level. 7. Remote monitoring is achieved through the Bluetooth module.
