The SOS Leak Sensor can detect water leaking into an improperly sealed Watertight Enclosure quickly and reliably before any major damage can occur! Though we are confident in the quality of our Watertight Enclosures and a leak is unlikely, the SOS Leak Sensor will give you additional peace of mind that your electronics are safe.

Four re-usable sponge-tipped probes with an adhesive backing let you monitor all corners of a Watertight enclosure, from the penetrators to the front and rear flanges. When a leak is detected, the signal is pulled high to VCC and bright red LED shines, making it easy to integrate with an Arduino, Raspberry Pi, Pixhawk, and many other 3.3v or 5v devices. The ArduSub firmware supports the SOS Leak Sensor on the Pixhawk by default.
