Story

Story behind the project

A member of our team visited Huangbizhuang Town, Luquan District, Shijiazhuang City last year, and found that the place is surrounded by mountains and rivers, and is close to Huangbizhuang Reservoir and Hutuo River Scenic Area. It is a good place to develop tourism.However, due to the shortage of young labor in the village, it is difficult to expand the scale and increase the income of farmers. Agritourism, as an important method of rural development, has encountered considerable resistance due to the shortage of labor. Therefore, there is an urgent need for a smart product that farmers can afford, so our team designed a Smart Agriculture Assistant.

Project Introduction-Functions, How to use

Function introduction of Smart Agriculture Assistant:1. The soil is monitored by the soil moisture sensor, and the water pump is controlled according to the soil moisture value for irrigation2. Real-time monitoring of air temperature, humidity and light value, and master crop growth indicators3. Rainwater monitoring and alarm

Process and steps

1. Group brainstorming

2. Select the sensor

3. Write code and debug

4. Design 3D appearance structure renderings

5. Use a laser cutting machine to cut appearance structural parts

6. Test

7. Assembly project hardware, assembly appearance
