The Oversea Bilge Pump Sensor is a self-powered wireless sensor which attaches to your bilge pump and monitors its activity, so you can be alerted if your boat is taking on more water than would be considered normal.

The Bilge Pump Sensor detects when the bilge pump is turned on and relays bilge activity to the Oversea Hub using a long-range radio frequency (RF) connection. You can specify how quickly and how often you want to receive alerts about bilge pump activity, allowing you to manage alert volumes appropriately based on normal bilge pump activity on the boat.

The Hub relays the bilge pump data to the Oversea app on your mobile phone, and generates alerts in the app, by e-mail and/or by SMS based on your specified parameters

Because of the long range of the sensor’s RF connection, you can use a single Hub to monitor bilge pumps on more than one boat, provided the other boats are close by.

The Bilge Pump Sensor is small (2.75″ x 3.75″ x 1.15″), lightweight (5.5 oz.) and built to withstand harsh marine conditions (IP65/67). It is powered by 2 off-the-shelf replaceable AA batteries, which provide 5 to 10 years of operation per set of batteries.

The bilge pump sensor ships with a plug-in bilge cable kit, as well as with screws, Velcro tape and magnets to mount the sensor box adjacent to your bilge.

Remember, Oversea devices require a subscription to activate, and currently only provides monitoring for boats located in the United States. You’ll find more information on subscription rates in the adjacent subscription tab.
