Water level control system using PLC and wireless sensors

This paper describes a water level control system, using SIEMENS LOGO! 24RL Programmable Logic Controller (PLC), RTX-MID-3V transceivers, converters and a pump controlled by electrical motor. The maximum water level, the minimum water level, the correct functioning of the motor driven system or some errors that can appear during the functioning of the motor driven system are visually signalled by LED-s connected to the PLC-s outputs. The goal of this paper is to present a low cost method for a water level control using a wireless solution.
