Sensor Operation Verification
If you have more than one WS-03, you can verify sensor accuracy. The temperature sensors should be
within 4°F (the accuracy is ± 2°F) and the humidity sensors should be within 10% (the accuracy is ±
5%). Allow a few minutes to stabilize.
Discussion
:
Temperature errors can occur when a sensor is placed too close to a heat source..
To verify temperature accuracy, we recommend a mercury or red spirit (fluid) thermometer. Bi-metal
(dial thermometers or thermostats) and other digital thermometers are not a good source and have their
own margin of error.
Discussion
: Humidity is a difficult parameter to measure electronically and drifts over time due to
contamination. In addition, location has an adverse affect on humidity readings. Note that indoor and
outdoor humidity varies greatly so you cannot accurately compare your humidity to official weather
station sources, such as the news or National Weather Service.
Due to manufacturing tolerances, the humidity is accurate to ± 5%.
