Microsmall Motion Sensor Module

The main function of this PIR module is realized by the human body pyroelectric infrared detection IC + photosensitive transistor + PIR sensor composition, IC at the same time detects the photosensitive transistor voltage and receives the change signal of the PIR sensor to control the output (OUT) high level / low level, in order to achieve the function of the load demand.

Precautions:


1. Do not operate with electricity, wait until it is installed and then energized.


2. It is strictly prohibited to use the inductive module with VCC and GND or VCC and OUTPUT (output) reversed, so as not to damage the module.


3. There is an initialization time of about 15 seconds after the inductor module is powered on, during the initialization time, the output will be high, and then the inductor module will enter into the normal sensing state (in the case of low illuminance environment) or shut down state (in the case of high illuminance environment) after 15 seconds.


4. Install the induction module as far away from the load as possible to avoid interference; not to install the finished induction lamp in the place of direct light or hot and cold airflow import and export; do not have mechanical switches and other electrical appliances in the power supply circuit of the finished induction lamp as far as possible, otherwise it is easy to cause interference to produce false operation.


5. Normal induction state output high level can be repeated after the trigger, until the person leaves the start of the delayed shutdown. 6.


6. There are long and short sides of the induction unit, and the lens tangential to the direction of walking, the induction is more sensitive, the induction distance; other directions of the induction sensitivity is lower.


7. The induction module is affected by the ambient temperature, individual differences, human body wear, walking speed and walking direction and other factors. General ambient temperature is low, the induction distance is normal far; but the ambient temperature is high, the sensitivity will decline, the induction distance will be shortened, this is a normal phenomenon. 8.


8. The application of this module should be matched in strict accordance with the parameters, and should not exceed the range, so as not to damage the module.
