    This work tries to improve the communication link of the data transmission in wireless sensor monitoring. The upstream communication link is usually based on standard IP technologies, but the downstream side is always masked with the proprietary protocols used for the wireless link like ZigBee, Bluetooth, RFID, etc.

    WebTag allows a direct web access to the sensor tag by means of a standard web browser, it reads the sensor data, configures the sampling rate and implements IP based security policies.

    It is, definitely, a new step towards the evolution of the Internet of Things paradigm. Introduction Sensor monitoring had seen its own technological revolution in the low scaling of the wireless communication technologies. As soon as the electronic technology was able to offer good performance—in terms of power consumption and cost—in analog to digital converters ADC , data processing units and radiofrequency front ends, wireless embedded systems were integrated with sensor technologies for a non-intrusive monitoring [ 1 ].

    The result is nowadays known as wireless sensor networks WSNs and it is considered one of the key topics in communication engineering [ 2 ].

    A WSN is made up of distributed devices known as nodes or tags with some kind of sensing capability to monitor physical or environmental parameters. They are connected wirelessly creating different type of networks based on the IP wired technology and they cover a large range of application areas, mainly when power or infrastructure limitations make a wired solution difficult to use. Despite the maturity of the WSNs, there are still many challenges to overcome, like the increase of the computational power of the sensor devices with lower power requirements [ 3 ]; more robust encryption [ 4 ] and security techniques [ 5 ], an energy efficiency increase [ 6 ], new network architectures [ 7 ], better network deployment [ 8 ] or more efficient data routing strategies [ 9 ] and communication protocols [ 10 ].

    The interaction within WSNs, i. External 9V battery is used to power the RTC. The window-comparator architecture of the LM92 eases the design of temperature control systems. The host can program both the upper and lower limits of the window as well as the critical temperature limit. Two pins A0, A1 are available for address selection. Pins 1 and 2 of temperature sensor IC3 are connected with pins 21 and 22 of IC1, respectively. The address pins 6 and 7 are connected with Vcc as shown in Fig.

    The device includes a capacitive polymer-sensing element for relative humidity and a band-gap temperature sensor.

    The 2-wire serial interface and internal voltage regulation allow easy and fast system integration. All routines for all distributions are contained in file routines. Note that none of these parts nor schematics were included in the Development package. However, a brief ASCII diagram is included with each routine and using this along with the manufacturers data sheet should be adequate.

    This installment is a bit late and not as complete as I would have liked. Once school begins, there isnt all that much free time when my mind is also alert and it doesnt take much to bog me down for some time.

    The next installment will be distributed well before April 15, but it may be somewhat abbreviated. However, dont depend on getting all of this.

    The price goes up as more material is developed. Any exposure you can give in promoting this effort and feel comfortable in doing so, would be greatly appreciated.

    I enjoy doing this, which is good as the arithmetic is not. But, as I say, I do enjoy it, but would like to see it become a bit larger revenue generator. Of course, I havent taken into account the movie royalties!


    SPI Master continued. The DS is one of the most versatile real time clocks I have used with such features as; 1.

    Powering the device with a single supply, powering with a single supply while trickle charging a second backup supply and a single supply with battery backup. The DS provides a register and the associated circuitry to control the trickle charge. The device provides a number of time alarm features including alarm each day, hour, minute and second or alarm when the time matches the alarm registers and this is tied to two alarm outputs which may be used as interrupts. However, this routine is limited to writing a date and time to the device and then periodically reading and displaying the date and time and reading the time, calculating the elapsed time in the current day and writing to and reading from the RAM at locations 0x20 0x7f.
