This is a simple water sensor, that can be used to detect soil moisture Module Output is a high level when the soil moisture deficit or output is low Can be used in a module plant waterer device, and the plants in your garden no need people to manage
The soil moisture module is most sensitive to the ambient humidity and is generally used to detect the moisture content of the soil Module to reach the threshold value is set in the soil moisture, DO port output high, when the soil humidity exceeds a set threshold value, the module D0 output low
The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture The digital outputs DO shop relay module can directly drive the buzzer module, which can form soil moisture alarm equipment Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture also fit for electronic games, electronic building blocks, Arduino designs, etc

Application
- Agriculture and farming: Soil moisture meters are extensively used in agriculture and farming to monitor and manage soil moisture levels. They help optimize irrigation schedules, prevent overwatering or underwatering, and improve crop yield and quality.
- Landscaping and gardening: Soil moisture meters find application in landscaping and gardening to ensure proper watering of plants and lawns. They help homeowners and gardeners maintain healthy plant growth and conserve water by providing accurate information on soil moisture levels.
- Environmental monitoring: Soil moisture meters are employed in environmental monitoring systems to assess soil moisture content in natural ecosystems, forests, or wetlands. This data is crucial for ecological studies, watershed management, and predicting drought conditions.
