A data collection module for performing a sleep study is described. The data collection module includes a first module, a second module, and a collection control module. The first module receives an electrocardiogram (ECG) signal from an ECG sensor connected to a user. The second module receives an electroencephalography (EEG) signal from an EEG sensor connected to the user. The collection control module: communicates with a mobile computing device in response to a prompt from the mobile computing device, stores data samples generated based on the ECG and EEG signals in a tangible computer readable medium and selectively transmits the data samples to the mobile computing device.
