Protoptype Pengairan Sawah dan Monitoring Kualitas PH Tanah Berbasis IOT

Rice is a food crop commodity that produces rice which plays an important role in the economic life of Indonesia. as staple very difficult to replace by other staples. This study aims determine results design internet-based monitoring system for field irrigation and soil pH with Thinger.io. The tools used this are Node MCU ESP8266, Ultrasonic Sensor HC-SR04, Soil Sensor, Servo Motor (MicroServo 9G – SG90), UTP Cable. sensor can send acidity level data NodeMCU thingger display results, while ultrasonic read elevation value on surface if water (11 cm) then servo will receive signal open when height ( 6 close, last process web server or thingger.io. test equal 7 it suitable planting seeds below not dolomid lime be added neutralize paddy fields. tests carried out using BlackBox method runs expected
