Remote RF/GSM SystemsAn
academic researcher based in a University required a number of sites to
be monitored for temperature with data being logged and available for
remote users to view out of office hours.
Each site had a number of temperature sensors located in storage
bins. The sites were in a remote location many miles from the
nearest communication network. A system was developed to allow up to 256 temperature sensors to be monitored at each site. A number of sites could be monitored by the same system. The system, developed in collaboration with the user, included a server, a base station and a number of remote loggers. The remote loggers collected data from temperature sensors. These were then transmitted to the base station via RF. The base station collected the results from all the remote loggers and transmitted these results to the server via GSM at set intervals. The server created graphic web pages which could be viewed in real time on a website. |
Market Research LoggersA
large multinational consumer corporation required a system to log trial
customers using new products. Loggers
were designed to fit into spaces within the product and log events such
as temperature changes, being picked up or changes in use.
These events were then stored in memory together with the
time/date and in some instances measurements.
This system replaced the self-logging diary method used by most
market researchers. The
data was more accurate and did not allow trial users to enter incorrect
data. A number of versions
were developed for a variety of products. Data was either stored on the logger and analysed after the trial was completed, or could be transmitted via RF to a base station and viewed in real time.

Micro-potentiostatWhistonbrook Technologies were awarded a 2 year KTP programme to investigate the possibilities of producing a single chip, low cost instrument. A graduate was employed to work on the project and a micro-potentiostat was developed in collaboration with the University of Hertfordshire. A demonstration micro potentiostat approximately the size of a 50 pence piece was successful developed and tested. Later RF wireless communication was added to allow the potentiostats to be completely sealed in water-proof enclosures. |
