Abstract
An indoor/outdoor thermometer system employs a wireless infrared telemetry link. An outdoor unit capable of being mounted on or in proximity to a window is equipped with a processor and modulation means to enable measurement of outdoor temperature and conversion to modulated data pulses. The data pulses are coded to provide noise immunity. The data is transmitted in a free space infrared medium and detected by an indoor unit which displays the outdoor temperature. The indoor unit is mounted in a suitable convenient indoor location. Indoor temperature may also be measured and displayed. An internal timing data transmission feature is employed to drastically reduce power consumption, enabling long lasting lithium type batteries to be deployed as the power source.
