Design of Temperature and Humidity Monitoring Equipment For Capillarity Irrigation of Mustard Plants (Brassica Juncea) With ESP32 Microcontroller

Abstract

 Problems arising on agricultural land, such as temperature and humidity, are difficult to avoid. This research aims to create a tool for monitoring the temperature and humidity of mustard plants in capillary irrigation and determine the appropriate temperature and humidity for mustard plants. The microcontroller used is ESP32, AHT10 as a humidity and air temperature sensor, and DS18b20 as a temperature sensor (water and soil temperature). The measurement results will be displayed on the LCD (Liquid Crystal Display) and sent to the database. The research was conducted for 30 days at the screenhouse of the West Nusa Tenggara Agricultural Instrumentation Standardization Agency. The results of the 1st week of observations showed that the average water temperature was 25℃, soil temperature 19℃, air temperature 29℃, and air humidity 95%. The result of the 2nd week of observations showed that the average water temperature was 25℃, soil temperature 19℃, air temperature 27℃, and air humidity 86%. In the 3rd week, the average water temperature was 25℃, soil temperature 19℃, air temperature 28℃, and air humidity 91%. In the 4th week, the average water temperature was 26℃, soil temperature 19℃, air temperature 31℃, and air humidity 97%.
