This thesis explains the design of a microcontroller-based device, which provides an efficient and practical alternative for the remote reading of digital electricity meters over Public Switch Telephone Network (PSTN). As an alternative application, a system is constructed providing file transfer capability to the PC connected to the port of implemented device in addition to remote reading of digital electricity meters. This thesis also provides detailed explanations about the basics of serial asynchronous communication over modem for PICs (peripheral interface controllers) together with description of each component included by the constructed system, which can be used in energy metering sector commonly.

Sari, Ibrahim; Balkan, Raif Tuna; Külah, Haluk (2008-06-25)
In this paper an electromagnetic vibration based micro power generator is presented. The proposed generator is composed of parylene cantilevers on which planar coils are fabricated. The system uses external vibrations to generate power by virtue of the relative motion between the cantilevers and a magnet. The parameters of the micro generator have been optimized for maximum output and it has been fabricated in micro scale. Initials tests show that 8.75 mV could be obtained from the proposed generator at a v...
An electromagnetic energy harvesting system for low frequency applications with a passive interface ASIC in standard CMOS
Rahimi, Arian; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2012-12-01)
This paper presents a compact energy harvesting system, which consists of an electromagnetic (EM) generator converting ambient low frequency vibrations to DC voltage by using a highly efficient full-wave rectifier in a System-on-Package (Sop). Frequency Up-Conversion technique has been utilized by the in-house EM transducer to harvest energy from very low frequency vibrations (<5 Hz). The interface ASIC is a passive rectifier based on the boot-strap rectification (BSR) technique to decrease the effective th...
