			Note that this means that you can measure the temperature of objects from ''any'' distance provided the object is of sufficient size. This is a bit counter-intuitive but true. You could measure the temperature of the sun from 7.9 million kilometers away though the data would admittedly be about 26 seconds old.

			===Maximum effective distance===
			In order to determine the maximum distance the 1045 can be effective at we first need to understand how the sensor measures temperature. The 1045 takes in IR radiation in a conical pattern from directly in front of the black canister mounted on the board. The field of view (FOV) of the device is rated at 10°, to illustrate:

			[[File:1045_FOV.png\|link=\|600px\|center]]

			The 1045 measures temperature by averaging the temperature of all points inside it's FOV. This means that if the surface you are trying to measure the temperature of doesn't occupy the entire FOV, the average will be thrown off by the temperature of the surrounding surfaces. Ideally then the surface you are measuring should be close enough to cover the entire 10° arc:

			[[File:1045_FOV_Occupancy.png\|link=\|600px\|center]]

			This means that the theoretical maximum distance you can get accurate readings from is the distance at which a circle that is the base of a 10° cone has a radius equal to the surface being measured:

	IR measurements are true surface temperature measurements. For example, when measuring the temperature of a person, the actual temperature measured by an IR thermometer will be temperature of the clothing and not the skin temperature. Emissivity of the clothes is another issue that has to be considered.		IR measurements are true surface temperature measurements.

	The 1045 is factory calibrated in wide temperature ranges: -40 to 125 °C for the ambient temperature and -70 to 382.2 °C for the object temperature.		The 1045 is factory calibrated in wide temperature ranges: -40 to 125 °C for the ambient temperature and -70 to 382.2 °C for the object temperature.

	To get ~~the most~~ accurate reading, it is important that the object being measured occupies the full field of view of the sensor while not making physical contact with the sensor. Since an infra-red sensor measures temperature based on what the object is emitting, there is theoretically no limit to the range of such a sensor, except that the further away from the sensor the object is, the larger the area of detection is. If the object being measured doesn't occupy the full area, the emissions of other objects could reduce the accuracy of the reading. In addition, the temperature of the object and of the environment also affect the overall accuracy. The highest degree of accuracy is +/- 0.5 degrees Celsius when both the ambient temperature and the object temperature are between 0 and 50 degrees Celsius. As either temperature changes, the accuracy can decrease to up to +/- 4 degrees Celsius.
