Integrated sensor nodes with GSM modems simplify the task of wireless data acquisition: Page 5 of 5

January 11, 2012 //By Ajay Bharadwaj and Balaji Mamidala
A sensor network typically consists of a number of sensor nodes which each acquire signals from a sensor or multiple sensors and a system to transmit and process the data acquired from sensors. The sensor nodes can communicate the data within one another or to a centralized location over a wired or wireless network.
need for specialized hardware for each different kind of sensor. Such System-on-Chip-based (SoC) MCU also have the capability to handle all tasks required for the sensor node in a single chip, including ADC, DAC, PGA’s, comparators, op-amps, digital filtering capabilities, DMA, and LCD controllers, among others. Design of the system using SoCs allows frequent and fast changes in design to assist customization of sensors nodes. PSoC with its low power capabilities at sleep mode is very suitable for these applications.
