Drilled wells water level data recording system for irrigation of rainfed rice using Arduino and pressure sensor

Abstract

Abstract The use of groundwater is one of the alternatives used to increase productivity in rainfed rice fields. Various researches and technologies have been developed to suppress the negative effects of overuse of groundwater. One important parameter is the change in the water level around the well during the pumping process, which is observed through the observation well. For that, we need an instrument to measure changes in water level in real-time. This instrument was developed using the HDL 300 submersible liquid level sensor, which utilizes pressure changes from the water level. To connect the sensor with the Arduino Uno microcontroller module using the HW685 Module. The calibration results show that the linearity of the change in the sensor value to the change in the water level reaches 99% following the equation y = 86.297x + 73.522.
