Wireless Gas Detectors With Wireless Control Unit:
The WGD-Series Wireless Gas Detector is a complete stand-alone system with integrated battery. These WGD-series along with the Local Receiver Unit SIG2RCV, are one of the recent technologically upgraded products which work on GSM/GPRS systems and can easily interface with Oxygen, Methane, Combustible & Toxic gas sensors. They eliminate the use of physical cables that were required for signal / data transfer between the conventional detectors & multi-channel monitors. Highlighted Features of WGD-series device are: Battery and Solar powered, Cloud connectivity, Cloud based data storage, SMS and Email alert / notification. These wireless data communication features integrated within these devices, use the constantly evolving technologies related to the Internet of Things – IoT category.
