Abstract: An example apparatus, method, and computer program product for reducing power consumption while maintaining a high accuracy in a sensing device is provided. The example apparatus may include a microcontroller and a sensing device electrically connected to the microcontroller. In an instance in which the microcontroller is enabled, the microcontroller may enable the sensing device and enter a low-power mode for a pre-determined sensor wait time. The microcontroller may further be configured to, upon expiration of the pre-determined sensor wait time, receive electrical data from the sensing device. Further, upon receipt of the electrical data, the microcontroller may disable power to the sensing device. In some embodiments, the apparatus may include a switch electrically connected between the sensing device and a power source, wherein the microcontroller is configured to send an electrical signal to the switch to control an input power to the sensing device.
