1 Piece HC-SR501 High Sensitivity Human Infrared Sensor
Module Pyroelectric PCB
Article-Nr.:2802164
Product Details:
� Human Infrared Sensor Module
� Condition: New
� :Product Feature:
Probe LHI778, high sensitivity
� Technical parameters: 1.Operating voltage: DC5V to 20V
2.Static power consumption: 65 microamps
3.Level output: 3.3V, low 0V
4.Delay time: adjustable (0.3 seconds to 18 seconds)
5.Blockade Time: 0.2 seconds
6.Trigger Mode: L can not be repeated, H can be repeated default value H
7.Sensing range: less than 120 degree cone angle of less than 7 meters
8.Operating temperature: -15 to +70 degrees
9.PCB Dimensions: 32 * 24mm, screw hole distance 28mm, screw aperture 2mm
sensor lens size: (diameter): 23mm (default)
� Features: 1. automatic induction: when someone enters its sensing range
input high, people leave the sensor range automatic delay off high. Output low
2. photosensitive control (optional): module is reserved for the location, you can
set the photosensitive control, daytime or light sensing. The photosensitive
Control optional features not installed at the factory photoresistor. If necessary,
please purchase separately photoresistor install it yourself
3. two trigger modes: L can not be repeated, H can be repeated. Jumper
selectable, default is H
A. not repeat the trigger mode: the sensor output high, the delay time has elapsed,
the output automatically from high to low.
B. repeatable trigger mode: the sensor output high, the delay period, if human
activities within its sensing range, the output will always remain high until people
leave only delay the high level goes low (sensor module detected after every
activity of the body's automatic postponed a delay period of time, and the last time
activities as the starting point of the delay time)
4. induced blockade time (default setting: 0.2 seconds): sensing module in every
sensor output (high to low) followed by set up a blockade of the time, in this period
of time the sensor is not receiving any induction signal. This feature can be
achieved both of the (inductive output time and the blocking time) interval can be
applied to the interval detection products; This feature can effectively suppress the
various interference generated in the process of load switching
