Zigbee wireless modules with smart sensors

Abstract

This paper deals with intelligent instrumentation in wireless networks. The significant parts are created tasks with the wireless technology. These tasks are formed with the Freescale ZigBee modules 13192-EVB or Microchip modules PICDEM Z. The 13192-EVB module includes RS232 and USB (FTDI chip) interface to connect with the PC, ZigBee chip MC13192 for wireless communication, 8-bit microcontroller MC9S08GT60 with A/D converters, switches and LEDs. Programmed additional subroutines are realized on evolutionary board Axiom AXM-0308 mounted with the Freescale MC9S08GB60 (HCS08). The PICDEM Z module includes RS232 interface to connect with the PC, the additional card with the wireless ZigBee chip CC2420, 8-bit microcontroller PIC18LF4620 with A/D converters, switches and LEDs.
