GSM activated watering system prototype

it is a challenge to maintain soil moisture for plants. Current watering system offered scheduling scheme as the solution, which might cause the soil to be too wet during the rainy seasons and too dry during the draught season. This prototype uses Arduino Uno R3 board which is easy to program and economical. It is programmed in such a way that it will sense the moisture level of the soil and supply the water if required. This type of system is often used for general plant care, as part of caring for small and medium orchard for small and medium enterprise (SME). Therefore, the microcontroller has coded the system to water the plants according to the reading from the moisture sensor which has been calibrated. On top of that, this system is extended using GSM technology, which enables the user to control the motor by sending and received the SMS (Short Message Service). So, by sending a SMS the user can look after his farm remotely. An easy access to the watering system using GSM technology is what the prototype offers.
