Abstract

A programmable gauge having a read out (gauge), a microcontroller, an input to microcontroller, and an infrared receiver is disclosed. A handheld infrared transmitter is used to communicate with the programmable gauge. In some embodiments, the programmable gauge further includes an output control signal. In a nonlimiting example, the input to the microcontroller is a temperature sensor and the infrared transmitter is used to select a set point. When the microcontroller senses a temperature above the set point, the microcontroller provides an output signal, for example, to turn on a fan.
