Conservative data exchange also 'plays' a very significant role in power conservation.

Hi Dale, Yes conservative data exchange and ad-hoc sharing of computational load while processing/transmitting data over large area could be very beneficial in power critical applications. Regards Umanath

Thanks for the article. What frequency range does the PSoC3 work on? 2.4GHz ISM band? Does it include the radio? Which kind of radio? Bluetooth? Zigbee? Thanks for the very interesting topic.

Hi Luis, The radio can be interfaced to PSoC3 via SPI. We do have our transceivers (CYRF7936) which work on 2.4Ghz ISM band and could be useful for short range connectivity with sleep currents below 1uA. Over the longer range, one can use GSM or wi-fi connectivity to link PSoC3 to the internet for data upload. There is one custom component in PSoC design software Creator for interfacing with WLAN board from Redpine Signals.Alternatively for GSM, one can interface over UART from PSOC3 with off the shelf chip such as SIM300. Regards Umanath
