Project Background

Environmental sensing is an emerging industry which will shape and support human activities. Large sensor networks exist to gather vital soil information such as soil moisture and salinity. Wired communication between sensor nodes is very cumbersome and infrastructure heavy. In contrast, standard wireless protocols in the microwave region require significant power and reduce battery life. In this project, the Very Low Frequency (VLF) range (30 kHz) has been sought as an alternate method of transmission. Additionally, Software-defined Radios (SDRs) have been used for both the transmitter and receiver. The use of an SDR allows for reduced hardware complexity and lower power consumption. Digital and analogue circuitry, a loop antenna and software have all been addressed to construct the system.
