Sense4Boat – Smart Battery Sensor


Smart Battery Sensor

This sensor continuously monitors (every 15min) the voltage and temperature of your batteries and warns you about any relevant action required to properly maintain the batteries to avoid damage due to sulfation and deep discharging. Whenever a voltage change larger than 100mV is detected, a message is sent to the cloud service and compared with the customer-specified thresholds for diverse alerting conditions (low/critical/charging/high temperature). If those threshold are exceeded, an automated email/push messages are generated and delivered to multiple recipients specified by the customers or shared with the Proactive Boat Care providers (see below). The sensor will also inform you about the start and finish of the charging cycle, as well as monitor the battery temperature during the charging/discharging to avoid overheating (boiling) of the batteries. All measurements are stored in a cloud for further analysis and can be retrieved anytime by a provided mobile application.

The sensor monitors one battery bank (for example service batteries) supporting both 12V or 24V electrical networks. First year subscription included in the initial price!
