The remaining components including the transmitter were placed a distance away behind two concrete walls from where the telemetry signals were received without any difficulty. When a failure was forced by placing the receiver to close to the PC a red Fail indicator in the display window was switched on. It was observed that when the signal was just on the edge of reception the received data become corrupted and as a result incorrect values were displayed.

The elegance of this system lies in its expansion capabilities. Conrad themselves supply a range of sensors, not all of them being described in this article. The greatest possibilities lie however in using the sensor inputs as feedback for a control system. Whilst the format of the data packet is not described in detail it should be relatively easy to work it out. Then a control system could be written around the sensor data.
