A measurement system comprises a measurement unit, a transmitter, an autarkic power unit and a control unit. The measurement unit measures a quantity repeatedly and the transmitter connects the measurement system to a network and transmits data to the network based on the measurements of the measurement unit. Further, the autarkic power unit supplies electrical energy to the measurement unit, the transmitter and the control unit. Additionally, the control unit controls the measurement of the quantity and the transmission of data dynamically based on a currently available amount of energy provided by the power unit. Further, the control unit stops measurements by the measurement unit and keeps the transmitter connected to the network, if the currently available amount of energy is below a predefined energy limit indicating that the currently available amount of energy is too low for taking measurements and for keeping connected to the network. |
