As a wind instrument made of wood and piping, the Reddel Memorial Organ is sensitive to both temperature and humidity. Therefore, measuring the microclimate surrounding the organ can lend useful insights concerning its tuning. The organ is a large, intricate instrument, with many sections to it. A thorough understanding of its microclimate therefore requires a number of sensor units to distribute throughout its ranks. These units need to be self-contained and low maintenance. Battery-operated, low-power radio communication presents an optimal solution to this problem. One can minimize the power demands of sensor nodes by offloading more resource-intensive tasks like uploading data to the internet to a wall-powered master node, in addition to many other system optimizations. Once a robust system is developed, it is a straightforward enough procedure to modify the sensor units such that they can measure any aspect of the environment that one could wish for, such as light level, atmospheric pressure, noise level, flexion of a beam, or proximity to an object.
