eK Leak Sensor is designed to alert users of any water leakage. It is connected to eKoral controller via bluetooth. Place the sensor flat on a solid surface where water leakage may occur. When leakage is detected, the sensor will send a warning signal to the eKoral controller which will then send a push notification to the user’s mobile device through the eKoral App. The user can also setup conditional control on the eKoral App to take appropriate actions when there is a leakage to prevent further damage. The sensor works in both freshwater tank and saltwater tank.
