Abstract :
This paper presents a batteryless transmitter for wireless sensor systems. Unlike the conventional battery powered sensor transmitters, our proposed transmitter is powered from a cellular energy-harvesting circuit, a microwave energy transmission technique that has capacity to harvest 3.2 V in 5.5 hours at 0 dBm of incident cellular signals (2 GHz). The transmitter is built around a 2.4 GHz nRF24L01+ programmable radio chip, controlled by a PIC16F877A MCU via a Serial Peripheral Interface (SPI). A 5 min successful locked carrier transmit test was carried out at ISM band channels (2.402, 2.440, and 2.850 GHz). The cellular energy-harvesting circuit described in this work is rated 36.16 mW max, given 11.3 mA maximum transmit drain current.
