Fuel level sensors
With Tank Manager application Android app you can use any Android tablet or even mobile phone as a local interactive display and data transmitter modem.
The tablet should be installed in the nearest building where we can get a stable Bluetooth Low Energy signal from the sensors (up to 200 meters in the direct visibility range). The application will display fuel volumes in the tanks and send data to the remote server using Wialon IPS or MQTT protocols.
Eurosens Tank Manager Android Application works with both commercial tracking platform software (Wialon) or with a free open source IoT Thingsboard platform that helps minimize the cost of a project. The application sends email notifications when fuel volume in each of the tanks drops below a set threshold.
