Smart Garden Based on Microprocessors

Currently, controlling of plants is done manually, where the farmer and people use hand labor to water the plants. Technological advancement is taking place in every sector and we are unable to stop it in this lifetime as it will always follow scientific discoveries. As a result, the goal of every invention is to improve people’s life and make it easier. If there is adequate supply of water, plant growth will be phenomenal. One way to reduce human error and take appropriate action during low rainfall or harsh weather is through creation of a system that monitors the plant and takes actions if needed. A prototype microprocessor based system for smart garden that uses ATMega328P as the controller, soil moisture sensor to sense the soil moisture and dht11 sensor to sense the temperature and humidity. The process output is sent to a 16×2 LCD screen which displays the soil moisture, humidity, temperature and triggers automatic watering and cooling.
