Link Kit Includes BG-GWM-W Gateway & BG-WS-01 Sensor Wi-Fi Non-SubscriptionThe BG-Link IoT Marine Gateway is a unique wireless monitoring system which primarily focuses on monitoring and alerting vital boat functions such as battery power systems and bilge functions through direct access to the internet cloud. Keeping the boat owner or designated user informed with 24/7 information about events taking place in the vessel’s bilge system. Regardless of the size of the vessel, it is easy to configure individual compartments, battery banks, down to all devices that are being monitored. Blue Guard Innovations Switches and Sensors communicate to the  gateway via a 900 MHz wireless connection. The is capable of monitoring up to 50 individual sensors. It uses built-in WiFi connection to access the internet cloud or an optional cellular connection. It is housed in a rugged IP-66 rated ABS plastic enclosure with convenient mounting options. The  features visible LED indicators for power, WiFi, cellular, and sensor connections. It is powered with voltage ranging from 9-30 Vdc. User configured alarms such as pump activation rate in an hour, voltage & current, temperature is then sent to designated e-mail or user BG-Link App. Wireless sensors are compact, lightweight, and easy to install in small spaces. Gateway - BG-GWM-W:Supports up to 50 sensors.
