In present era, only few sensors are used for chemical applications such as ground water monitoring, chemical identifiers and so on. In this paper, we have detailed about how to improve the utilization of sensors in the chemical industries and also proposed some new ideas to researchers to make sensors for chemical industries, according to their need and machinery systems of organic industries. This paper concentrates on minimizing the hazards of chemical wastages, by implementing efficient monitoring sensors in and around the chemical industrial environment. This paper also recommends the unavoidable requirement of sensor motes in the world of chemical industries. The main objective of this paper is to provide infrastructural ideas to the researchers, regarding sensor monitoring and merging of sensors from various area of applications to chemical industry applications and the results are proving that the emerging trend brings effective control over the variables.

INTRODUCTION A sensor is an electronic device used to measure a physical quantity and convert it into an electrical signal which can be read by an observer or by an instrument. Recent advances in Micro Electro mechanical Systems (MEMS) technology have enabled the development of low- cost, low power, multifunctional sensor nodes. Wireless sensor network (WSN) is an autonomous network of a number of sensor nodes, very small in size and communicate in short distances. WSN operate unattended, adaptive to the environment [1]. Hence, widely used in applications for military, environment and health monitoring, for home and other commercial areas. Sensors are now widely used in the chemical fields and chemical industries for identifying the chemicals and monitoring of petrol tanks in petro chemical industries and all. Zigbee is a new standard; intended for low cost devices in automation, home controls and computer peripherals. It enables the broad-based deployment of wireless networks with low cost, low power solutions. A. Sensor Node Usually sensor node have four unit.That are;1)power unit,2)processing unit,3)sensing unit , and 4)transceiver unit. Figure:1 sensor node architecture[2] Initially power unit generates the power. Processing unit have the microcontroller,which is the fully responsible to get sesned data and transmit over the another network. The controller performs tasks, processes data and controls the functionality of other components in the sensor node. Sensing unit has the sensors and analog to digital converter (ADC) to convert analog sensed signal to digital signal. 224 224 2011 2nd International Conference on Environmental Science and Development IPCBEE vol.4 (2011) © (2011) IACSIT Press, Singapore
