| Summary: | Water is a valuable resource, but not all communities can afford to use it liberally. It is now crucial to use the water that is available as effectively as possible, particularly in agriculture. An unattended ground moisture sensor can be used to monitor the present moisture level in the soil surrounding the plants in order to decrease overwatering of crops. So, a farmer will be able to decide when to water and when to stop. The user should receive the moisture data information wirelessly for convenience. It is detailed how to develop a wireless communication and user interface system for an unattended ground moisture sensor. The Wheat stone bridge for determining il is followed by a differential amplifier in the resistance of the sensor design. Transforming the resistance that was measured into a voltage. This is carried out because resistance and moisture are correlated. A Lora communication transmitting node sends this voltage together with a Lora communication receiving node, where a microcontroller interprets it as moisture data. The receiving node then transmits the data to a PC host so the user can access it. a power circuit that uses a linear regulator and a battery.
