1. A method comprising:
commencing, by a controller within a sensor device and in response to pressing of a button on the sensor device, sensing of physiological activities of a fetus from a belly of a first pregnant patient;
calibrating, by the controller, one or more sensors within the sensor device based on historical data stored in a cloud database communicatively coupled to the controller, wherein the historical data comprises data from a previous pregnancy of the first pregnant patient, wherein the data from a previous pregnancy of the first pregnant patient were obtained by the sensor device prior to the calibration;
determining, by the controller, counts of the physiological activities per unit time once the one or more sensors have been calibrated;
identifying, by the controller, a type of each of the sensed physiological activities; and
for each type of the sensed physiological activity:
in response to an amount of time associated with the type of sensed physiological activity elapsing, transmitting, by the controller and to a cloud computing server, the counts of the type of sensed physiological activity per unit time over the amount of time for assessment of fetal health for the first pregnant patient.
