Wireless Sensor Products
In
conjunction with the RF development team at LPA Design, the developers of PocketWizard™,
Microprocessor Designs has developed
the capability allowing us to bring your wireless sensor
needs to market very efficiently. We have developed
custom hardware, firmware and wireless system
design knowledge that gives us the capability to ensure that your product,
whether it be a simple data acquisition system or a multi-sensor wireless
system, will be to market on time and on
budget. Contact us with your your
needs.
Radio
and Baseband Processor with Analog Front End
Applications:
The
architecture approach allows for a wide variety of applications. Some of these
include:
 |
Wireless
Sensors - multiple sensors including accelerometers, thermistors,
thermocouples, pressure, FSRs, tilt, angle, and more |
|
Wireless
Protocol Converters - wireless to wired protocols include USB, CAN,
RS485/422/232, I2C, SPI |
|
Long Term Data Acquisition - low power remote
sensors with very efficient sleep modes allow for months of data acquisition
without operator intervention |
System Design Highlights:
| Frequency Agile Radio - as compared to other sensor designs
which use fixed frequency SAW (916.5 MHz, 868 MHz, 433 MHz, etc.) based designs, this
design allows for many frequency selections and 'clear air' detection. The
design currently uses the 902-928 MHz ISM band. The radio transmit
power is set below FCC regulations. |
| Up to 38.4Kbaud Data Throughput |
| 100 Meter Operation |
| Hitachi H8S Baseband Processor - a very capable and
flexible kernel that allows us to optimize performance using a high level
language ('C') for your specific needs |
| Multiple Receivers - 254 wireless units , expandable to
65534 units |
| CRC-16 Forward Error Detection - Ensure data integrity |
| Automatic Remote 'On-Air' Address Assignment - the user
need not set dip switches or pre-assign addresses - the system will
automatically assign and addresses to each active device |
| Flexible Host Computer Interface - the system currently
provides the user with a straight forward DLL interface allowing quick
connections to most programming environments (Microsoft Visual C++,
National Instruments Labview/CVI, etc.) |
| Low Power - allows for long operational life in the
field |
| Wide Operating Voltage - 1.8V to 3.6V (2 Alkaline/NiCD/NiMH
cells, 1 Lithium cell) |
| Small Size - 2.75" x 1.20" x 0.75"
without batteries |
| Standard 8 channel, 10-bit Data Acquisition - up to
16 bit quantization available |
| Wireless 'In-Situ' Flash Reprogramming - allows you to
reprogram the units remotely with any disassembly or cabling |
| Multiple Memory Configurations - up to 32 Mbytes
Flash, and 1 Mbytes SRAM |
| Multiple Triggering Configurations - units can be
configured with linear or circular data buffers allowing you to look at data
BEFORE the trigger event |
| USB Host Interface - allows for high speed host access and
host computer power |
| RS232 Host Interface - standard interface for older or
WinNT based machines |
| Multiple Memory Configurations - up to 32 Mbytes
Flash, and 1 Mbytes SRAM |
| Compact Flash Interface - allows for removable media and
802.11b wireless Ethernet cards |
