Application Notes

While it is our primary goal to deliver powerful products that are easy to deploy and use, we understand that the development process can be a challenging experience. In addition to offering turnkey solutions from IntelliSensing WSN Integration Services, we provide extensive product documentation on three levels:

 


  AN101 - Measure Single Reading
  This application note describes the use of the Measure Single Reading (MSR) command. This command allows the user to collect a single packet of measurements from a sensor. Included in every packet of measurements are: received signal strength, primary pressure, reference pressure, primary temperature, battery voltage, and module temperature.

  AN102 - Measure Multiple Readings
  This application note describes how to use the Measure Multiple Readings (MMR) command.  This command first performs a single full measurement as described in the Measure Single Reading (MSR) application note and the MSR section of the user manual.  Next, several higher speed measurements containing only the primary pressure measurements are acquired.

  AN103 - Measure Tare Offset
  This application note describes how to use the Measure Tare Offset (MTO) command.  This command performs an operation that nulls the primary pressure measurement.  After the operation is completed, the next primary pressure measurement should be at or close to 0% full scale pressure.  Use this command if the primary pressure offset value is believed to be incorrect.

  AN104 - Sensor Battery Level
  This application note describes the use of the Sensor Battery Life (SBL) command.  This command allows the user to view a sensor’s estimated remaining battery life.  The battery life is given as a percentage of full capacity.  The energy capacity of a new battery can be determined by observing the sensor’s control parameters.  This value is crucial in determining the remaining battery life.

  AN105 - Sensor Reset
  This application note describes how to use the Sensor Rest (SR) command.  This command simply resets the sensor engine.  The only other way to be able to reset would be to disassemble the sensor’s casing, remove the battery and then replace it.  This command is useful if the sensor is not easily accessible and can not be manually reset.

  AN106 - Sensor Control Parameters
  This application note describes use of the Sensor Control Parameter (SCP) command.  This command either writes to or reads values from the sensor.  In the SCP section of the user manual there is a table which lists and describes all of the SCP identifiers.  Several sensor control parameters will influence how the measurements are acquired and how the results are computed.

  AN107 - Radio AT
  This application note describes the use of the Radio AT (RAT) command.  This command allows the user to read or write a value stored in a sensor’s XBee module AT register.  This command is helpful for changing XBee parameters without disassembling the sensor.  The various AT commands are listed in Appendix B of the user manual.  Be aware that improper use of this command may render the sensor inoperable.

  AN201 - Communication with Multiple Sensors
  This application note describes how to communicate with multiple sensors via a single BaseStation.  A single packet of measurements (primary pressure, reference pressure, primary temperature, battery voltage, and module temperature) may be obtained from multiple sensors in succession, using the Multi Test Application that is supplied on our Software Distribution CD which ships with our products.
  2 pages / 148KB
 

  AN202 - Setting Units of Measure
  This application note describes how to set the units of measure for any collected data.  The Factory Setup Application, included on our Software Distribution CD, will allow users to configure their sensors according to a few initial conditions.  For example, the units that pressure readings may be acquired include:  PSI, INHG0C, FTH2O4C, KPA, MBAR and TORR.  Also, temperature readings can either be acquired in degrees Fahrenheit or Celsius.

  AN203 - Network Addressing
  IntelliSensing’s sensors and base stations are both factory set to have the same default networking parameters stored in their memory.  If there are multiple sensors attempting to communicate, for example, on the same communication channel, then there will be interference.  One way to work around this would be to change the Channel and/or PAN ID parameters of the sensor as well as the base station.  This application note describes how to properly configure a sensor with a base station.

  AN204 - Restoring Default BaseStationOne Settings
  This application note describes the BaseStationOne U/R restoration process. Restoring the factory default settings is essential in the event the PC can not communicate with the BaseStationOne. These instructions assume there is one BaseStationOne connected to the computer.

  AN205 - IntelliSensing WSN Workbook
  This application note describes the use of the IntelliSensing WSN Workbook. The WSN Workbook is a comprehensive sensor monitoring and data logging system for use with IntelliSensing temperature sensors.
