Signatrol now offers an affordable alternative to hard-wired monitoring systems. Spydaq, a low-cost wireless temperature and humidity monitoring system, is suitable for tracking air temperature in all kinds of environment.

Spydaq allows users to deploy sensors in various locations without the restrictions and cost of hard wiring and monitor results from a PC, either locally or using web access.

The company is offering the hardware free of charge in return for use of the software especially developed for use with Spydaq, so there is no capital investment.

The Spydaq system consists of a BaseStation which receives data from up to 16 remote transmitters and passes it to a PC either via a Modbus RTU or by GPRS direct to the Spydaq website. Each remote transmitter can have up to three inputs – temperature, relative humidity and universal – and sends it via a licence-free ISM radio band using a data redundancy system to ensure virtually error free data acquisition. Multiple antennas can be connected to ensure reliable radio connection from diverse areas.

Users can choose from up to 16 transmitters to be located at points for monitoring. Such transmitters include room sensors, duct sensors, external sensors, immersion sensors, pipe mount sensors and fridge/freezer/oven sensors, which can be combined to suit the required application. A typical application would be around six sensors, with larger more complex sites requiring all 16 sensors.

A choice of operating frequencies means that two systems can be run concurrently side by side providing up to 32 transmitters for even larger applications.
