Abstract: A data logger is disclosed as having functional units, arranged inside a housing, for detecting, digitizing, optionally storing and optionally evaluating measurement data and for transmitting data to an external data processing device, and a power source, such as a button cell battery, arranged inside the housing. The functional units for detecting, digitizing, optionally storing and optionally evaluating measurement data and for transmitting data to an external data processing device are arranged on a printed circuit board, which forms a component of the housing of the data logger. The housing of the data logger forms at the same time the housing of the power source, whereby at least one electrical contact for the power source is provided on the housing.

Abstract: A data logger includes functional units for acquisition, digitization, storage and evaluation of measurement data and for wireless transmission of data to an external data processing device. The external data processing device provides photographic acquisition for recording of static and/or dynamic patterns of electromagnetic radiation. An optical indicator device emits and/or reflects electromagnetic radiation. The functional unit for data transmission is coupled to the optical indicator device such that data will can be transmitted in coded form via time-controlled and/or intensity-controlled activation.

Abstract: A data logger is disclosed wherein a common housing includes different function blocks which are connected to one another. These function blocks include at least one analog/digital converter for conversion of measurement signals into digital input data, a memory unit for recording of digital data and of digitized event data, a timer, a processor unit for processing of data, a power supply source and input and output interfaces for measurement signals or digital data and event data. The processor unit is configured for conversion of digital input data and time data into a format which is compatible with standardized software (e.g., freely available) and which makes it possible to display the processed data using standardized software in tabular and/or graphic form on an output device.

Abstract: A data logger for collecting, evaluating and displaying data, such as climate data, generated from measured values is disclosed, which has different function units within a common hardware housing. These units include a collection unit, a storage unit and a control and evaluation unit which is connected to the other units. A USB interface for digital data exchange with an external data processing system is included on the housing. The USB interface can be operated both as a digital interface for digital data exchange, and as an analog interface for receiving analog measurement signals.
