spYdaq - Low Cost Wireless Monitoring Solutions

 

spYdaq is a system comprised of a number of radio transmitting sensors that measure parameters and sends them securely by using a license free radio network to a central Basestation. The data are sent using a Manchester Encoded error correcting code with multiple transmissions which, when combined with Antenna Diversity, ensures there is no loss of data in normal use from a properly installed system. Up to 16 transmitters can communicate to a single base station with each transmitter capable of having up to three inputs: Temperature, Relative Humidity or Universal (Universal inputs can be configured to accept almost any type of measurement sensor). The base station collects the data from the transmitters and connects via an RS232 serial port configured as a Modbus slave to our spYview software or any other Modbus master. There is also a USB port used for initial configuration of the base station using our spYconfig software.

The wide range of inputs offered by the universal transmitter design enables virtually any parameter to be measured and logged by connecting an appropriate sensor. Parameters that can be measured and logged are:

• Temperature
• Humidity
• Pt 100
• Thermocouple Types J, K, T, R, S
• 4-20 mA - Scaled in engineering units
• Voltage
• Contact Closure

The Basestation checks locally for alarm conditions with inbuilt audio and visual alarms as well as providing a switched contact output that can be used to trigger external devices. Alarming locally means that potential trouble spots can be quickly detected and corrective action taken immediately, perhaps saving an entire batch from damage.
