6. CAUTIONS
1. This module detects a change of infrared energy. This module does not only detect a
moving human body but also other heat sources similar to human temperature.
2. This module cannot detect the presence of a human body if it does not move.
3. This module detects changes of infrared rays through the Fresnel lens.
Detection areas and range depend on its surface condition.
4. To prevent malfunctions, operational failure or any deterioration of its characteristics, do not use this
module in the following, or similar, conditions :
rapid ambient temperature changes
strong shock or vibration
high humidity and temperature
Unit troubles resulting from misuse, inappropriate handling or storage are not the manufacturer’s
responsibility.
