Online Monitoring and Alarm Indication of Status of Air for Automation

Safety is the most important part of any type of industry. Negligence in the safety may cause damaging of production or may cause loss of human life [14]. To avoid harm due to wrong pressure, wrong humidity of air and to avoid separate man power to control these things, company can invest in this automation based project rather than investment in separate man power. By using this project users can see current status of air on LCD, also higher authority can control parameters of air by PC. Zigbee is used here for wireless communication between PIC microcontroller 16F877A and PC. Here we used 4 sensors- pressure, temperature, vibration and dew point sensor. Output of pressure, temperature and dew point sensor will be displayed on LCD but output of vibration sensor will be given to buzzer.
