• a battery operably coupled to the microprocessor;
• a display device operably coupled to the microprocessor;
• a single button operably coupled to the microprocessor;
• and
• a first digital interface operably coupled to the microprocessor;
• a second circuit board including:
• a second digital interface, the second digital interface being operably coupled to the first digital interface;
• and
• a digital infrared sensor operably coupled to the second digital interface, the digital infrared sensor having ports that provide only digital readout signals, the digital infrared sensor comprising a low noise amplifier, an analog-to-digital converter, a digital signal processor, and a pulse width modulator (PWM) in a single industry standard package;
• wherein the digital infrared sensor is configured with no need for recalibration after an initial factory calibration with an emissivity range from 0.1 to 1.0;
• wherein the microprocessor is operable to receive from the ports of the digital infrared sensor the digital readout signals that are representative of an infrared signal, the infrared signal acquired from a forehead of a user and generated by the digital infrared sensor, and the microprocessor is further operable to determine the temperature from the received digital readout signals by using the PWM, and
• wherein no analog-to-digital converter is operably coupled between the digital infrared sensor and the microprocessor,
• wherein the wireless communication subsystem transmits to a static Internet Protocol address in order to reduce Internet Protocol discovery burden on the device.
