Design & Implementation of Data Acquisition & Controlling System Based on Free RTOS Platform

Data acquisition and controlling (DAC) system refers to provide solution which is capable of making measurement and controlling external processes using variety of hardware and software. The proposed design and its implementation of DAC system based on the freeRTOS platform. The suggested system is used to monitor and control industrial applications. The proposed system is design on open source hardware Arduino platform in which freeRTOS Application programming Interfaces (APIs) is installed and configured. As part of the hardware, here three basic sensors are used as temperature sensor for measuring temperature, flame sensor as measuring the flame and ultrasonic sensor as measuring the water level in the tank. Buzzer and LEDs are used as the controlling devices for flame sensor, whereas motor is used as the controlling device for ultrasonic sensor. Here temperature sensor is used as monitoring device. The proposed system can justify the remote monitoring and controlling task through the network using the web browser. The proposed system continuously monitors the sensor values and displays it onto the web browser. If the sensor value is exceeds from the threshold values, it will take necessary controlling actions.
