Abstract:
1. A temperature sensor device comprising: a light emitter operable to emit a first light having a first color and to emit a second light having a second color that is different than the first color; a body housing the light emitter; a radiation detector operable to detect temperature of a first target when the temperature sensor device is pointed at said first target and operable to detect temperature of a second target when the temperature sensor device is pointed at said second target; and a trigger operable to control operation of a trigger switch such that the operation of the trigger causes the trigger switch to responsively generate a trigger switch signal that is employed by a controller to control the light emitter and the radiation detector; wherein when the radiation detector detects a temperature of the second target that is less than a threshold amount different than the detected temperature of the first target, the light emitter emits the first light at the second target and wherein when the radiation detector detects a temperature of the second target that is more than a threshold amount above the detected temperature of the first target, the light emitter emits the second light at the second target.
