spYdaq Wireless data logging and monitoring system

Introducing spYdaq – a brand-new, world-class wireless monitoring system that is adaptable, efficient, easy to use, reliable, and highly cost-effective.

With spYdaq, you can deploy sensors in all kinds of situations and locations – including many where hard-wired systems cannot go – and monitor everything directly from a PC desktop with our easy-to-use software. You can even monitor remotely from a laptop, or any computer anywhere in the world, using our special GPRS/web link.

At the heart of the spYdaq system is the BaseStation, which receives data from up to 16 remote transmitters, and passes it to a PC, either via a Modbus RTU, USB, or by GPRS direct to the spYdaq website, whch can be accessed anywhere in the world. Each transmitter can have up to three inputs – temperature, relative humidity and universal – and sends it via a licence-free ISM radio band, using a sophisticated data redundancy system (patent pending), to ensure virtually error-free data acquisition.
