NeuLog heart rate and pulse logger sensor can be used to monitor and compare pulse rates under various exercise and rest conditions. Additionally, it can show changes of blood volume/flow in the finger or ear lobe with time. The sensor has two modes of operation: measuring the BPM (Beats per Minute) of the heart rate or displaying the analog arbitrary value of the measured signal. The electrodes are both plethysmograph-based. The sensors consist of an infrared LED transmitter and a matched infrared phototransistor receiver. For best results, the sensor should be kept away from direct sunlight and high intensity lights. The student whose pulse is being measured should be still without moving as much as possible.
The logger sensor consists of a data logger, flash memory, and a sensor for fully self-contained data gathering, and is plug-and-play for immediate readings as soon as it is connected. The logger sensor sends data in digital format to a PC, Mac, tablet, smart phone, or other viewer device, and provides multiple connection options, including USB and wireless. The logger sensor’s browser-based software adjusts ranges and gains, and provides applications for presenting data, including online and offline modes, tables, graphs, data analysis, double-axis set up, statistic operations, and mathematical operations. The logger sensor is encased in durable plastic, and has an LED indicator to track experiment status, with push buttons for calibration and start/stop experiments in offline mode for ease of operation. To take an assortment of readings during a single experiment, the logger sensor can be attached to another sensor; one to 10 logger sensors can be used per experiment (sensors sold individually). For efficiency, the logger sensor can store up to five experiments in flash memory, and saved experiments can be uploaded to a PC or Mac at any time. Additional accessories, such as USB, Wi-Fi, or battery modules, are required for operation depending on the device (PC, tablet, viewer, and so on) used to receive readings from the sensor. (Accessories and devices sold separately.) The logger sensor includes a guide with instructions for use and care, and measures 6.5 x 7.0 x 1.5cm (L x W x H). (L is length, the horizontal distance from left to right; W is width, the horizontal distance from front to back; H is height, the vertical distance from the lowest to highest point.)
