Wireless relative humidity and temperature data-logger
spYdaq Signatrol Ltd

spYdaq® is a system comprising of a number of radio transmitting sensors that measure parameters and send them securely by using a licence 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 has a number of ways of recording the values:
GPRS connection - An internal GPRS modem sends the values direct to our secure managed servers

RS232 serial port configured as a Modbus slave to any Modbus master.

USB - USB connection to a local computer running our spYmonitor-local web interface.
