Level tank system by sigfox

Function description:

The device is composed of a level sensor (ultrasonic sensor) and a temperature sensor. On the outside, a battery can be recharged itself using sunlight. The device is watertight and has of a tamper

of protection for the case of vandalism. Once a day the device should transmit via Sigfox the measurement level. The value obtained is transmitted to a server. This information can be managed according to the customer requirements (filling alarms, route to each collection area, statistical reports, etc).


Micro-controller and components should be compatible with Arduino.

The final product is the prototype in Arduino, the schematic and the gerbers for the PCBA.

Battery lifetime: 3 years

Communication protocol: LPWAN (Sigfox)

Protection: IP68

Localization via GPS (optional)

Ultrasonic and temperature sensor

IOT transmission by using a server (and API)

Квалификация: Arduino, Программирование на С, Электротехника, Электроника, Микроконтроллер
