Delayed Adjustable Metal Detector Sensor Module Light Operated Motion Detector

Product Specification

delayed, adjustable, light-operated, Infrared Sensor Module

Multifunctional adjustable induction

Human body has a constant body temperature, general to 37 ° so will issue a particular wavelength of about 10 um infrared, passive infrared sensor is by detecting the human body and 10 um ir, so other objects except the body does not trigger probe movement.Once the intrusion detection area, the human body infrared radiation through part of the lens focus, and pyroelectric receive, and the output signal.Subsequent circuit after detection treatment generate control signal, will receive a weak signal amplification, and then drive relay, is made from the pyroelectric body induction switch.

product functional features

1. Automatic induction: when someone enter its sensing range input high level, people leave the induction range automatically delay closing high.The output low level.
2. Photosensitive control (optional) : the module's reserve position, can install photosensitive control, strong or light during the day without induction.Photosensitive control for optional features, the factory not installed when the photosensitive resistance.If you need, please buy separately.
3. Two trigger modes: ab cannot repeat, the BC repeatable.Can jump line selection, the default for the BC.
A. not repeatable triggered: after induction output high level, delay time is over, the output will be automatically from high level to low level.
B. repeatable triggered: induction, the output level in the delay period, if there is the human body in its induction within the scope of activities, the output will always keep a high level, it was not until after the people left time delay will be high level to low level (induction module detects the human body after each activity will be automatically postponed to a delay period, and in the last activity time for delay time), the starting point of the.
4. Induction block time (default setting: 30 seconds) : after induction module in every sensor output (high level to low level), can be followed by setting a block of time, in this time period sensors do not receive any sensor signal.This function can be achieved (induction output and blocking time) the interval of the work, can be applied to interval detection products;At the same time, this function can effectively restrain the load switch process of all kinds of interference.
5. Wide working voltage range: the default working voltage DC4.8 V to 15 V.
6. Micro power consumption, static current 65 microamps, especially suitable for a battery-powered electric products.
7. A signal output level: easy to dock with the various types of circuit implementation.
 

the application occasion

Corridor, corridor, toilet, basement, warehouse, garage and other places of automatic lighting, exhaust fan convulsions and other electrical appliances (incandescent lamp, fluorescent lamp, buzzer, automatic doors, electric fan, automatic washing machine and dryer) especially suitable for the enterprises, hotels, shopping malls, sensitive area or warehouse safety and alarm system.Can also be used for security purposes.

1. Electric induction module initialization of a minute or so after the time, in this module will be time to 0-3 times, a minute into the standby state.
 

2. Try to avoid direct lighting and other interference sources close to the module on the surface of the lens, lest produce false action in the introduction of jamming signal;Using the environment to avoid flow of wind, the wind will also cause disturbance to the sensor.
 

3. The induction module adopts dual probe, the probe window is A rectangle, the dual (RMB yuan B) in the long direction at both ends, when the body from left to right or from right to left through the infrared spectrum to time and distance of the dual difference value, the greater the difference, the more sensitive, when the body from the front to probe, from top to bottom or from bottom to top direction passed by dual test is less than the change of infrared spectrum distance, there is no difference, so not sensitive or not work;So when installing sensors should make the probe of the dual direction and the direction of most human activities in parallel as far as possible, ensure the body passed successively induced by dual probe.In order to increase the induction angles, this module USES round lens, also makes the sensor probe all directions, but both sides still bigger than two direction sensing range, strong sensitivity, when installation should also be as far as possible according to the above requirements.
