This paper describes the design and realization of a simple and low-cost system for distributed measurements. Traditional handheld digital multimeters have been equipped with a radio-frequency interface in order to implement what the authors call WDMM, the basic block of a wireless multi-probe data logger. New functionalities require very few components and result in a cost increase of less than 10$. In addition, also maintenance has been facilitated since tracking data such as working state or last calibration time are available to the user. Data inquiry can be performed by a purposely designed module that has the same hardware of the WDMM but a different user interface or by a PDA (Personal Digital Assistant) or a traditional personal computer thanks to a USB connection. Simple supervisory software has been realized under the LabVIEW graphical programming environment.
