9 Environmental Stability

If the sensor is used in equipment or machinery, make sure that the sensor used for

measurement and reference- sense the same temperature and humidity. If the sensor is

placed in the equipment, the response time will be prolonged, so ensure that sufficient

measurement time is reserved in the program design. The AHT25 sensor is tested according

to the company standard of the temperature and humidity sensor of Aosong. The performance

of the sensor under other test conditions is not guaranteed and cannot be used as a part of the

sensor's performance. Especially for specific occasions required by users, no promises are

made.

10.2 Tracking Information

All ATH25 sensors have laser marking on the surface, and are accompanied by markings for

parameter descriptions, see Figure 12. The anti-static bag is also labeled, as shown in Figure

13, and provides additional tracking information.
