摘要:It is an automation system for checking the moisture content in the agricultural fields and watering them accordingly eliminating the manual effort. A soil moisture sensor is used to analyze the moisture content in the soil and it will update the information to the smart phone integrated with the sensor. The motor or sprinkler involved in watering the fields are turned on and off automatically through relays. The moisture content is monitored throughout the watering with the help of flow sensor and the humidity sensor is also used to monitor the humidity in the atmosphere of the fields. The watering is stopped when the crops reach an optimum level. This leads to conservation of water and ensures healthy crops. Nowadays, the farmers are suffering from lacking rain and water scarcity. The traditional farm land irrigation technique requires manual intervention. Whenever there is a change in humidity these sensors sense the change in humidity and gives an interrupt signal to the micro-controller. Thus water is supplied to the farm land in efficient and sufficient manner
