The sensor’s measured temperature does not match the expected temperature?

• The following situations may cause a large temperature/humidity difference:

  • Sensor hardware damage (verification method: when you have multiple sensors, you can place multiple sensors in the same environmental, and the measured values differ by ± 1.8°F (± 1°C) is normal)

• The following methods can be used for problem troubleshooting:

  • Place multiple un-calibrated sensors in the same environmental and check if the data is consistent.

• ST7/ST5/ST4

• When the ambient temperature is between 185°F (85°C) and 257°F (125°C), it is normal for the measured values to differ by ±1.8°F (±1°C) among multiple sensors in the same environmental.

• When the ambient temperature is between 14°F (-10°C) and 185°F (85°C), it is normal for the measured values to differ by ±0.9°F (±0.5°C) among multiple sensors in the same environmental.

• When the ambient temperature is below 14°F (-10°C), it is normal for the measured values to differ by ±3.6°F (±2°C) among multiple sensors in the same environmental.

• ST3

  • When the ambient temperature is between -4°F (-20°C) and 140°F (60°C), it is normal for the measured values to differ by ±0.9°F (±0.5°C) among multiple sensors in the same environmental.

  • When the environmental humidity is 0~80%RH, the difference of the measured value is ±2%RH.

  • When the environmental humidity is 80~100%RH, the difference of the measured value is ±3%RH.

• If all the sensors meet the above measured difference values, it means that the temperature/humidity measured is normal.

• If there is a sensor that does not meet the above measured difference values, the sensor with a large difference in measured value is an abnormal sensor, which needs to be replaced and compensated.
