Zero Power Wireless Sensors Using Energy Processing

Implementation and Power Efficiency of Wireless Sensor Network for Environmental Monitoring in Agriculture

Abstract

In this paper we have implemented wireless sensors using Arduino (AVR 328) microcontroller. It is a single microcontroller solution which senses various environmental parameters such as temperature, humidity, and light intensity. Based on zigbee wireless technology, the temperature, humidity and light sensor network is composed of three parts: the transmitter, receiver and display system. The sensor network is powered by using solar energy. The current consumption of this wireless sensor network is 45 mA only. So the power consumption is very less. We can use this sensor to sense environmental monitoring condition in agricultural sector.
