In this paper, we have discussed about the development of a soil moisture sensor, integrated with GPS and cloud that can be utilized for several applications such as irrigation management wastewater reclamation. 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 in a wireless manner with the other devices to provide the soil moisture value as well as the latitude and longitude of the installed location with the help of GPS module integrated with it. Sensor has been calibrated by measuring the ground truth gravimetric soil moisture. A total of 16 samples were taken for developing the relationship between gravimetric soil moisture and output voltage, whereas more samples were used to validate the developed relationship. A good correlation is also observed between the soil moisture evaluated with developed sensor and ground truth gravimetric soil moisture. The data can be logged into SD card, and the developed device has the capacity to share the data with any Arduino IoT cloud platform through which we can examine and control the data of the device. We used Internet of things, as it paved a new path toward enhancing technology and getting it on our finger tips.
