	===Measured Temperatures===		===Measured Temperatures===
			The 1045 is factory calibrated in wide temperature ranges: -40°C to 125°C for the ambient temperature and -70°C 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 an accurate reading, it is important that the object being measured occupies the sensor's full field of view of the sensor while not making physical contact with the sensor. Since an infrared 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°C when both the ambient temperature and the object temperature are between 0°C and 50°C. As either temperature changes, the accuracy can decrease to up to ±4°C.

	To get an 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.~~

	~~The measured value is the average temperature of all objects in the 10° Field Of View of the sensor~~.

	The ~~sensor~~ is ~~configured to continuously transmit~~ the temperature of the ~~measured object every 32ms~~.		The measured value is the average temperature of all objects in the sensor's 10° field of view.

	===Board Temperature===		===Board Temperature===
			It is very important to understand that the specifications are only guaranteed and achievable when the sensor is in thermal equilibrium and under isothermal conditions (i.e. there are no temperature differences across the sensor package board). The accuracy of the 1045 can be influenced by temperature differences in the board. These differences can be caused by the following:
			*hot electronics behind the sensor.
			*heaters/coolers behind or beside the sensor.
			*hot/cold objects very close to the sensor that not only heat the sensing element in the 1045 but also the 1045 PCB.

	It is very important to understand that these accuracies are only guaranteed and achievable when the sensor is in thermal equilibrium and under isothermal conditions (there are no temperature differences across the sensor package board. The accuracy of the thermometer can be influenced by temperature differences in the board induced by causes like (among others): Hot electronics behind the sensor, heaters/coolers behind or beside the sensor or by a hot/cold object very close to the sensor that not only heats the sensing element in the thermometer but also the 1045 board.		The 1045 assumes that the ambient temperature has settled to a constant temperature. If the surrounding temperature is constantly changing, or if there is a difference of temperature across the sensor package, additional infrared radiation will be sensed which can result in temperature errors outside of the calibrated errors.

If the surrounding temperature is constantly changing, or if there is a difference of temperature across the sensor package, additional ~~infra-red~~ radiation will be sensed which can result in temperature errors outside of the calibrated errors.

	===Emissivity===		===Emissivity===

	In order to measure temperature using infrared radiation, it is absolutely essential to know the emissivity of the surface being measured. Emissivity is a measure of how effective a surface is at radiating energy. An emissivity of 1 is the most effective radiator - for a given temperature, it will radiate the most heat. The 1045 assumes that the surface being measured has an emissivity of 1. If the 1045 is used to measure a surface with an emissivity of 0.5, the measured temperature will be 50% of the difference in temperature between the board and object.

	A few examples of some materials with a large difference in emissivity are aluminum, with a typical value of 0.18, and plastics, which can have a value ranging from 0.85 to 0.95. The visible colour of the object does not necessarily mean it has a higher emissivity value. A heavily oxidized aluminum object has an emissivity value of around 0.3, even though it looks very dark. The closer the value is to 1, the better the object is at emitting radiation.

	Emissivity is a complicated topic, as it can vary depending on the temperature of the material. For precise measurements, you may have to calculate the emissivity of your material by comparing the reported Sensor Temperature to the actual surface temperature measured with a contact thermocouple.

	===Maximum effective distance===		===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:		In order to determine the maximum distance the 1045 can be effective at we first need to understand how the sensor measures temperature.
