Human infrared sensor module thermal release sensor Fresnel lens HC-SR501

Spell parameters:

1.Operating Voltage:DC 5Vto20V
2.Static power:65microampere
3.Level output: high3.3V,Low0V
4.Delay time: adjustable (3Second~250Second)
5.Lockdown time: approx.2Second
6.Trigger:LDo not repeat,HRepeated, the default value isH
7.Sensing range: less than120Capted angle,7riceInside
8.Operating temperature:-15~+70Spend
9.PCBDimensions:32*24mm, Screw hole distance28mm, Screw2mm, Infension lens size:(diameter)The23mm(default)

Features:
1.Fully automatic induction: When someone enters its induction range, enter high level, and people leave the induction range and automatically delay the high level.The output is low.
2.Optical control(Optional): The module has a reserved location, and can be set to light-sensitive control, and does not sense during the day or when the light is strong.Photosensitive control is optional,The photoresistor was not installed at the factory.If necessary, buy another optical resistance to install it yourself.

3.Two triggers:LDo not repeat,HRepeatable.Jumper selection, defaultHEssence
    A.The trigger method cannot be repeated: that is, after the sensing output is high, the delay time ends.The output will automatically change from high to low.

   B.Repeatable triggering method:That is, after the sensing output is high, if the human body is active within its sensing range during the delay period, its output will remain high until the person leaves. The delay will change the high level to low level.(The induction module detects each activity of the human body to automatically postpone a delay time period, and the time of the future activity is the starting point of the delay time)Essence

4.Sensing blockade time(default setting:0.2Second): The induction module is after each induction output(High level becomes low level)You can follow the blocking time, and the induction device does not receive any induction signals in this time.This function can be realized(Induition output time and blocking time)The interval between the two can be applied to interval detection products; at the same time, this function can effectively suppress various interference generated during the load switching process.
5.The working voltage range is wide: default working voltageDC4.5Vto20V
6.Micro power consumption: static current65Wei'an, especially suitable for power supply products for dry batteries.
7.Output high -level signal: It is convenient to connect with various circuits.

Instructions for use:
1.After the induction module is powered on, there is an initialization time of about one minute. During this period, the module will output 0-3 times at intervals and enter standby state after one minute.
2.Try to avoid the lens on the surface of the module at close range of the interference source, so as not to introduce the error movement of the interference signal; try to avoid flowing wind as much as possible, and the wind will also cause interference to the sensor.
3.The sensing module uses a dual-unit probe, and the window of the probe is rectangular. The double-unit (A-unit B-unit) is located at both ends of the longer direction. When the human body passes from left to right or from right to left, there is a difference in the time and distance from the infrared spectrum to the double-unit. The larger the difference, the more sensitive the sensing. When the human body walks from the front to the probe or from top to bottom or from bottom to top, the double-unit cannot detect the change in the infrared spectrum distance, and there is no difference, so the sensing is not sensitive or does not work. Therefore, when installing the sensor, the direction of the probe double-unit should be parallel to the direction where the human body is more active, so that the human body passes by one after another by the probe double-unit.In order to increase the range of sensing angle, this module uses a circular lens, which also makes the probe induction on all sides, but the left and right sides are still larger and more sensitive than the upper and lower directions. When installing, try to follow the above requirements.

Note: The adjustment distance potentiometer rotates clockwise, and the sensing distance is far 5-7Mi), otherwise, the inductive distance decreases (about3rice).

Adjust the delay potentiometer rotating clockwise, and the delay delay (about300S) On the contrary, the induction delay is shorter (approximate5STo.
