This chip is real amazing, because it is all in one. You just need an RFID antenna, what could be a PCB track and a battery. The rest will be done by the logic inside. If temperature logging is not enough, then you can add external sensors interface. Right now there is a humunity sensor […]

Is this an EEPROM with RFID transponder or a RFID transponder with EEPROM?
The M24LR64 is an electrically-erasable memory (EEPROM) that can also be programmed wirelessly by industry standard RFID (radio-frequency ID) equipment. Using the M24LR64 for program or data storage provides extra flexibility for customers, allowing software updates or specific parameters to be applied in the supply chain. With an easy implementation based on two industry standard […]
Android, Linux, QNX, Symbian and Windows in M2M applications
I already started several projects on embedded Linux (GE863-Pro3 or UC864-G + BeagleBoard). One is for example a metering project for a customer in India. Development and manufacturing is provided by a business partner of mine in Germany. The next higher level is based on BeagleBoard http://www.beagleboard.org. The BeagleBoard is an open source single board […]
Bluetooth low energy is an “always off” technology. Basically it stays in the lowest power modes
Because power consumption is so low, coin cells will typically last a year or more. Bluetooth low energy chips can operate either as slaves or masters and which device takes what role is decided during the initial negotiation. There is no reason for a tag to be the proverbial one-trick pony. Design cycles will be short compared to proprietary solutions because the design team can concentrate its efforts on writing application layer code instead of the entire protocol stack. Sensing a means of making mobile phones even more indispensable, Nokia and other manufacturers are clearly on the Bluetooth low energy bandwagon. “We see it as part of the continued evolution to the Bluetooth chip set,†says Mika Sarén, Nokia’s Senior Technology Manager for Connectivity. When the specification is released, it will be supported in time for the first product release on Forum Nokia, the company’s web site for developers.

Is RFDP8 better than BlueTooth, ZigBee, WLAN and other protocols?
RF Digitals RFDP8 proprietary patent-pending frequency agility protocol operates in the internationally accepted 2.4 GHz band. The RFDP8s leading-edge advanced algorithm is not burdened by a heavy-weight stack as is BlueTooth, ZigBee, WLAN and other protocols, which are well suited for cross-manufacturer interoperability. The RFDP8 protocol is highly robust and effective where there is a […]
