Abstract: With the advancement of CMOS technology power consumption of a microcontroller and wireless identification and sensing platform (WISP), it is now possible to design a WISP with zero energy. The WISP in this project consists of several key components such as the transponder (TMS37157), microcontroller (MSP430G2553) and Temperature Sensor (TMP100). The energy for the sensing platform is harvested from the LF Reader to provide sufficient power to the sensing platform. With Low Power consumption as the key factor for the entire design process, the sensing platform is designed to sustain its minimal operation required and send the data back to the LF Reader. The microcontroller acts as the brain for the entire platform and is responsible for the communication among all the internal components. By utilizing the Serial Peripheral Interface Communication mode and Inter Integrated Circuit Communication mode, the communication between the transponder, microcontroller and temperature sensor is established. Functions of the microcontroller such as Low Power Modes were used extensively to fulfil the low power consumption for the overall platform. With a wake up signal from the transponder, the microcontroller will wake up from the low power mode and perform its intended operation before entering low power mode. The overall system interface and program are designed with the knowledge of the allowable power budget.
