HW-1006 is a pyroelectric infrared sensor module that detects changes in infrared. It might not be capable of detecting heat sources other than the human body, or in cases where there are no temperature changes and movements of the heat sources. The following general considerations need to be noted. Please ensure the performance and reliability through the actual usage status.
When detecting heat sources outside the human body:
(1) When small animals enter the detection range.
(2) When using far-infrared direct radiation sensors for sunlight, car headlights, incandescent lamps, etc.
(3) When the temperature within the detection range changes significantly due to the heating and cooling air of the cold greenhouse equipment, as well as the water vapor of the humidifier.
When it is difficult to detect heat sources:
(1) When there are substances such as glass and acrylic that are hard for far infrared to penetrate between the sensor and the detected object.
(2) When the heat source within the detection range is nearly stationary or moving at a high speed.
When the detection area expands:
In situations where there is a considerable temperature difference between the surrounding environment and the human body (about 20 ℃ or above), even outside the specified detection range, there might be a broad detection area.
Regarding other uses:
(1) When there are stains attached to the window, it will affect the detection performance. So, please pay attention.
(2) The lens is made of a flexible material (polyethylene). After applying load or impact to the lens, it will cause poor movement and performance degradation due to deformation and damage. Therefore, please avoid the occurrence of the above situation.
(3) Applying static electricity above ± 200V may cause damage. Therefore, please be extremely cautious during operation to avoid touching the terminals directly with your hands.
(4) When welding wires, please weld them by hand at a temperature below 350 ℃ and within 3 seconds of the soldering iron. When welding through a solder bath, it may lead to performance degradation. So, please avoid it.
(5) Please refrain from cleaning this sensor. Otherwise, the cleaning solution may invade the interior of the lens and cause performance degradation.
