DAS-1 (Distance Alarming System) is a device for monitoring and alarming in case of sea intrusion into the boat. It is very easy to use. After the initial installation, the device returns a message with all the necessary data by calling or sending an SMS message: humidity, temperature, battery charge and the calibrated value of the liquid level in the bilge/bottom of the boat. In case of intrusion of the sea or spillage of marine liquids, if it comes to the alarm zone, it sends an SMS and calls the owner on the default mobile phone number. It also has a built-in relay that can be used to turn on/off the pump via SMS, 10A. You don't have to go to your vessel every day, just call or send a message and you have accurate values in a few moments. Save time and fuel driving to the halfway point by installing the DAS-1.
