IoT-based-Soil-Moisture-Monitoring-Device

This IoT project uses soil moisture sensor to notify the user when the soil gets too dry or too wet

Soil moisture plays vital role in plant growth and provides them nutrients. Therefore, it is important to detect the soil moisture content for proper development of plants. This IoT project uses soil moisture sensor to notify the user when the soil gets too dry or too wet. This device is developed on Arduino platform and has the capability to communicate with sound
