The Connect sensor is a battery-powered, enterprise-ready, cellular gateway solution for wireless connectivity at locations with either no power or low power. In offering a plug-and-play solution, the sensor allows for remote sensor monitoring to be deployed in environments previously considered too harsh, remote or not economically viable. It can accommodate off-the-shelf sensors, such as flow, level, pressure and environmental conditions. The application uses a Bluetooth connection to provide local installers, technicians or drivers with instant feedback on sensor values via Android and iOS smartphones or tablets. This provides local personnel with immediate status on possible actions.
