Wireless electronic nose using GPRS/GSM system for chicken barn climate and hazardous volatile compounds monitoring and control

The chicken industry is the largest component in the farming industry in Malaysia. It is among the main contributors to the sources of nutrition in Malaysia. The chicken barn condition must be ideal for good growth rate of the animal. Therefore, by monitoring and controlling the temperature, humidity and hazardous volatile compounds inside the barn will ensures good animal growth. The environments parameters inside the barn are monitored by using four electronic noses (enose) that located at pre-determine area. The instrument consists of gas, temperature and humidity sensors that measure the data in real time. The instrument's nodes are being link wirelessly to a base node using the internet for continuous monitoring. Data will be sent using ZigBee communication protocol to a microcontroller board (master node module). The acquired data from the nodes will be transmitted to a web page via General Radio Packet Service (GPRS). The same data will also be sent to farm owner mobile phone through short messaging system (SMS). The system will control the operation of the airconditioning system for maintaining the barn climate using fuzzy rules and PID control algorithm. The system will generate reports and patterns on the barn's temperature, humidity and hazardous volatile compounds through real time monitoring using web-based system. This will enable an early indicator of the unusual barn environment condition to ensure good animal growth. Initial result shows that the system is able to monitor and control the temperature, humidity and hazardous volatile compounds inside the chicken barn by using GSM/GPRS system.
