In this article, the author describes a low-cost, portable and flexible Sensor Configuration Unit (SCU) design for use in engineering measurements with various sensors. The unit consists of a sturdy ring stand, a plate with holes to hold various sensors, and a bracket fastened to the plate to hold the signal conditioning unit of the sensors and provide the input output connections. This puts the sensor to be used and its signal conditioning unit into a single central unit. The output from the sensor is connected to the measurements hardware and, more preferably, the computer data acquisition hardware, through the BNC connectors on the bracket. The set-up is very portable and has a minimal footprint on the experiment workbench. It eliminates the problems of many wires scattered around the workbench during experiments. The exchange of different sensors in the unit is easily carried out and enables purchasing standalone sensors for different engineering measurements applications for existing measurement hardware, instead of buying much more expensive all-in-one measurement units. This set-up is especially useful to an undergraduate measurement and instrumentation class in small size engineering programmes with limited budgets.
