Merancang Bangun Alat Kelembaban dan Pengukuran Pertumbuhan Tanaman Menggunakan Mikrokontroler Esp8266 dan Sensor Ultrasonik Berbasis IOT

Abstract

Plants are living things that are important for human life. Plant growth itself occurs as a process of increasing mass and volume which is irreversible, such as increasing the height, length and width of plant parts. The purpose of designing this tool is to find out the working principle and data analysis from measuring soil moisture and plant height. The working principle of this tool, the voltage source generated by USB power is to change the entire system and power the load. This whole system controls to be connected and the LCD displays data. Then a humidity sensor that measures soil moisture and an ultrasonic sensor that measures plant height. Blynk app that displays data on IoT. Data analysis from the measurement results is explained, data retrieval is carried out once a day with realtime IoT that can be read. The indication of a change in plant height is 4 cm and the soil moisture value is 14.7%.
