Introduction: Liquid Level Indicator

About: 4D Makers is a group of curious engineers and enthusiasts who finds great satisfaction in creating and building anything from electronics.

This project is a type of level detector capable of determining the liquid level in the container using Ultrasonic Sensor. It is a non-contact monitoring device attached to any container with a height up to 400 cm. It has a simple PIN security feature allowing the pre-set height reading of the container be secured.The device uses Gen4-uLCD-50DCT-CLB to change the pre-set parameters and to display the real-time liquid level readings.
