*Chemical vapors or pollutants

Exposure of the internal sensor to chemical vapors or high levels of pollutants may interfere with the internal sensor and cause a shift in both offset and sensitivity, resulting in inaccurate readings to be
logged. High levels of pollutants may cause permanent damage to the humidity sensor’s polymer.
