2.4G Wireless Grouping PIR Motion Sensor, PWM Dimming, Zhaga book20 Interface

• The sensor should be installed by a professional electrician. Please turn off the power before installing, wiring and changing parameters.
• PIR sensor can't penetrate any materials, please make sure no obstacle between sensor and moving people/object.
• Sensor may hard to detect people if wear thick clothes in cold winter.
• Heat signals will be regarded as moving signals to trigger the sensor. Avoid facing sensor to air condition or other heating source.
• Sensor is for indoor use only. Outdoor sunlight could affect the detection of sensor.
• Due to continuous improvement, the contents of this instruction could be changed without prior notice.
• The dimming performance could be different when work with different 0-10V drivers.
• The daylight threshold is measured in a sunny environment without shadow and ambient light diffuse reflection. Ambient lux level could be different in different environment, weather, climate, time-of-day and season.
• Detection distance is related to height of people, mounting height, mounting angle, working environment temperature and etc. When ambient temperature approaches the human body temperature range (36℃~37℃/96.8~98.6℉), PIR motion detection will significantly weaken or non-responsive. When ambient temperature or LED tray temperature is higher than 55℃/131℉, false triggering may happen, please try to reduce detecting sensitivity to improve. If stays false triggering, the PIR sensor should not suitable to be used in the space.
• Given detecting area is typical value that was measured by 165cm high testers in an indoor open environment.
• This product have to use with voltage-stabilized DC power supply whose input voltage is stable and ripple factor is low(ripple factor is lower than 100mV; load current is greater than 25mA).
• When installing in new environment, please install and test at least 5pcs product firstly before mass installation.

PIR Application Considerations:

PIR is a pyroelectric infrared sensor that detects changes in infrared rays. Please pay attention to the following matters during actual use:

• When detecting heat sources other than the human body
• When the temperature of the heat source does not change or the heat source does not move
• Other related environmental factors and violations of the PIR application principle impact

Potential False Triggering Scenarios:

• When small animals enter the detection range
• When far-infrared rays from sunlight, car headlights, incandescent lamps, etc. are directly exposed to the sensor
• When the temperature in the detection range changes drastically due to warm air, cold air from cold greenhouse equipment, water vapor from humidifiers, etc.

Potential Non-Triggering Scenarios:

• When there are substances such as glass and acrylic that block the transmission of far-infrared rays between the sensor and the detection object
• The heat source within the detection range hardly moves or moves at high speed
