Nowadays, the industrial automatization is the need of the hour for improving process in various industries. On survey, it is observed that, it may help to increase the quality, reduces cost and time to get the product in market. The physiochemical monitoring and controlling is the challenging task in the field of Industrial sectors. Considering such facts, it is proposed to develop Remote Terminal Unit (RTU) to monitor the physical parameter. The present research work is carried out to monitor the pH of water in water treatment plant. For this purpose, the RTU is wired with FRDM-KL25Z based ARM Cortex™ M0+ core microcontroller along with sensing and signal conditioning capabilities are used. Moreover, the sensed and processed signal is transmitted towards supervisory computer through RS232. On other hand, the pH of the water is recorded on the supervisory computer of Supervisory Control and Data Acquisition (SCADA) system. The RTU is calibrated to demonstrate the pH in standard unit. The developed system works successfully for monitoring the pH of water under experimental conditions.
