The proposed paper focuses on developing an embedded application for temperature monitor and control along with data logging, by implementing ZigBee protocol for wireless data transmission. The system comprises of central computing unit at field side and receiver at the user side. The central computing unit consists of a temperature sensor, signal conditioning circuit, ARM7 microcontroller and ZigBee RF module, whereas ARM7, LCD and ZigBee together form a receiver. ARM’s on-chip 10-bit ADC is used for digitizing analog signals from the temperature sensor which are further processed for control & wireless transmission. With this utilization, it is possible to design a cost efficient, reliable and accurate system which is perfectly suitable for monitoring parameters in real time process dynamics especially in hazardous environments.
