Description
Summary:Automatic irrigation is not new, this method has been invented by mankind to irrigate large areas of land through drip irrigation systems. The system is implemented to reduce water wastage in irrigation. In greenhouse irrigation control, computerized control is very important to increase productivity. On the other hand, conventional irrigation control in greenhouses is not effective, because it is based on on-off or proportional control. This paper presents a solution to control irrigation time duration based on fuzzy logic method. Fuzzy logic controller (FLC) was developed using the Mamdani method. FLC is built on the NodeMCU ESP8266 board mounted with a DHT22 and soil moisture sensor. Temperature and water content in the soil parameters are used as input for fuzzy logic to determine the duration of irrigation time. The linguistic values used as fuzzy membership functions include soil moisture (water, wet, dry), temperature (cold, normal, hot), and watering time (zero, short, medium, long). Based on the membership function, 9 fuzzy rule bases are determined. The testing results on fuzzy logic built on NodeMCU ESP8266 with fuzzy logic built on MATLAB software obtained an average error of 0.59%.
