For example, I am considering to buy the HTS221 Digital Temperature and Humidity Sensor by STMicroelectronicsHTS221 Digital Temperature and Humidity Sensor by STMicroelectronics. The datasheet says the operating temperature of the sensor is from -40C40°C to 120C120°C. But on page 33 of the datasheet, they say under accuracy, 15 to 40C40°C = +/- 0.5C5°C and 0 to 60C60°C = +/-1C 1°C. NeverThey never talk about Sub zerosub-zero and high temperature than 60Ctemperatures above 60°C.

  1. Does the operating temperature (-40 to 120C) mean that this sensor will not melt off during high temperatures like 100C, but I cannot expect it to measure that temperature?

  2. Does that mean that the temperature sensor can measure only from 0-60C with the above accuracy and the rest of the measurements are going to be way off?

How to find the actual measurement range of a temperature sensor, HTS221?
