SL622 PIR Motion Detecting Module

Product Overview

This auto-control product SL622 is based on the infrared line technology,

with high sensitivity, reliability and ultra low-power working mode. It

is widely used in all kinds of auto-detecting electrical equipment,

particularly dry battery supplied products.

Product Features

 Automatic Induction:

When people enter into the range of induction, it will output high

level; when people leave , it will turn off high level and output low

level with delay.

Photoresistor control (it is optional, defaulted setting: off):

Itwill trigger only in the darkness.

Temperature Compensation (optional, defaulted setting: Off)

summer, environment temperature raises  , which causes

sensing range shortening. The temperature compensation will make

some compensation for it.

Triggering in two ways:

A .Unrepeatable triggering mode:

It automatically turns to output low level.

B. Repeatable triggering mode:

After it outputs high level, during the delay period, if there is

presence of people, it keeps outputting high level until people leave,

then turns to low level. Each time the sensor detecting an activity

from human body, the module will automatically postpone a delay-time

period and start to count the delay time from the latest detected

motion.

 Sensing Blocking Time(Default: 2.5s)the module can set a blocking

time period after every output. During this period, the sensor will

refuse any kinds of sensing signal. The interval work between sensing

output time and blocking time can be used to interval detecting

products. Meantime, this function will effectively restrict the

interference in the load switching process.

 Optional Working Voltage DC3-18V
