The design of this automatic plant watering device aims to create an automatic plant watering system using the FC-28 sensor and a monitoring system using the Blynk application on papaya fields. In the system, the microcontroller used is an Arduino UNO with outputs, namely a dc pump, 16X2 LCD, and Blynk application. Based on the android interface app, the Blynk app can monitor the soil moisture value in real-time every 1 second. Data collection was done by measuring the moisture value in 3 papaya farms with different crop ages, and the tool will water when the soil moisture value read by the sensor is> 350 or <65%. Based on the study results, the device can run well, as shown by the pump can water when the soil moisture value is> 350 or <65 %, and the pump will stop when the soil moisture value is...

This measuring instrument consists of a series of infrared sensors, Arduino as a process, LCD I2C as a value viewer, Micro SD as a data storage, and RTC as a timer. This study used two water samples with various concentrations. The sample used, namely distilled water plus impurities in the form of soil and ash. The distilled water used is still 100 ml with variations in the concentration of impurities ranging from 0,1-0,9 gr. Sensor test results show that the greater the turbidity level, the greater the voltage obtained. Sensor scanning ranges from 2,02 V-4,00 V for groundwater and 2,02 V-4,31 V for ash water. The reading uses a standard measuring instrument for groundwater ranging from 0 NTU to 331,4 NTU, while for ash water ranging from 0 NTU to 284,4 NTU. Data from the sensor test results in an equation used to convert the artificial me...
