- This research is to designs and manufactures measurement level of soil water with pipes wells using ultrasonic sensor based on microcontroller arduino uno. How the work of this tool is when ultrasonics sensor on pin trigger given a positive voltage during time 10 μS then the sensor send 8 step ultrasonic signal or wave with frequency 40 KHz. Then when the wave hits a barrier then the wave it will be reflected back and received by pin echo. From this pulse will produce a distance measurement to be sent to microcontroller arduino uno. Distance range that can be detected by ultrasonic sensor US-015, which is between 2 cm and 4 cm. on this water level measurement tool, pipe wells perforated on its sides then coated with palm fiber then pipe is immersed into ground along 150 cm and 50 cm above ground level
