Infrared Temperature Sensor Specifications
1.1
Purpose
-
The imbedded infrared temperature sensor reads an object’s temperature as well as its own body
temperature and compensates for the body temperature.
1.2
Specifications
-
Industrial/commercial accuracy: +/- 0.5 ˚C (0-50 degrees C).
-
Each unit is factory calibrated and very stable over time. (Ref USDA internal report)
-
Narrow field view:
o
10 Degrees (50% sensitivity) (5.6:1 View Dist:Width)
o
15 Degrees for 80% sensitivity
i.e. at 15 degrees 80 % of the temp signal is included in view.
(4:1 View Dist:Width)
o
20 Degrees for 95% sensitivity
i.e. at 20 degrees 95% of the temp signal is included in view.
(3:1 View Dist:Width)

Data
2.1
Purpose
-
The purpose of the SapIP-IRT’s data collection is to provide the user with real time data
measurements. Typically the sensor will take 2 seconds to read the temp, and then the results are
either averaged or saved according to the collection steps.
-
-
Each set of data can be displayed in a digital format for when it is accessed wirelessly and
presented remotely in graphical format for crop temperature and stress analysis.
-
-
Analog data will be converted to digital data and presented in crop temperature and stress analysis
calculations. Since analog data is converted from digital and then converted back to digital, it is
inherently less accurate than digital and yet is very similar to non-IR rated temperature sensors.
