Product Description

Introduction
HW-1004 Based on digital infrared technology, automatic control products, high sensitivity, high anti-interference, strong stability, widely used in various types of automatic sensor circuit system..( Such as: toys; digital photo frame; security intrusion detection; occupancy detection; network cameras; private alarm; car burglar alarm; TV refrigerator air conditioning; sensor lights; intelligent home control systems and so on) 
I.Features:
1. digital signal circuit processing.
2. Two-way differential Very high impedance sensor input.
3. Special built-in infrared sensor second-order Butterworth bandpass filter, shielding other frequency input interference.
4. Power supply rejection ratio is high, anti-radio frequency interference.
5. With sensitivity, timing time, light sensor Schmitt REL output.
6. Low voltage, low power consumption, start working instantly.
7. Automatic induction: people into its sensing range is output high, people leave the sensor range is automatically delayed high, the output low.
 
8.When the probe receives a pyroelectric infrared signal that exceeds the trigger threshold inside the probe, a count pulse is generated internally. When the probe receives this again
Like the signal, it will be considered to receive a second pulse, once within 4 seconds after receiving two pulses, the probe will produce an alarm signal, while
REL pin has a high level trigger. In addition, as long as the received signal amplitude exceeds the trigger threshold of more than 5 times, then only need a pulse can trigger
REL output. The following figure shows an example of a trigger logic diagram. For multiple triggers, the hold time of the output REL is timed from the last valid pulse.

 V.Precautions
The HW-1004 is a pyroelectric infrared sensor module that detects infrared variations. Detection of heat sources other than the human body, or no heat source temperature changes and the movement of the case may not be able to detect. Need to pay attention to the following general matters. Be sure to confirm performance and reliability with actual usage status.
1.When detecting heat sources other than the human body
(1) Small animals enter the detection range
(2) when the sun, car headlights, incandescent lamps and other far-infrared direct sensor
(3) When the temperature of the detection range changes drastically due to the warm air of the cold room apparatus, the cold air and the water vapor of the humidifier, etc.
2. Difficult to detect heat source
(1) between the sensor and the detection of objects such as glass and propylene and other difficult to pass through the far-infrared material
(2) the detection range of the heat source is almost no action, or high-speed movement
3. When the detection area is expanded
In the case where the ambient temperature and the temperature difference of the human body are large (about 20 ° C or more), there is a wide range of detection areas even in the specified detection range.
4. About other uses
(1) When there is dirt on the window, it will affect the detection performance, so please be careful.
(2) The lens is made of a weak material (polyethylene). When the load or shock is applied to the lens, it will cause malfunction and performance degradation due to deformation and damage, so please avoid the above situation.
(3) When applying static electricity of ± 200V or more, it may cause damage. Therefore, please pay attention to the operation, to avoid direct contact with the terminal and so on.
(4) In the case of welding the wire, the soldering is carried out at a soldering iron temperature of 350 ° C or less and within 3 seconds. When welding with solder bath, it may cause deterioration of performance, so please avoid.
(5) Avoid cleaning the sensor. Otherwise the cleaning fluid intrudes into the lens, which may cause deterioration of the performance.
