New HC-SR501 Infrared PIR Motion Sensor Module Raspberry PI For Arduino

Important Information:

Solder Pads for Repeatable(H) mode & Non- Repeatable(L) mode

Centre Pad solder to H for Repeatable(H) mode (Normal Operation)

Centre Pad to L for Non- Repeatable(L) mode

These pins can be found in the top right hand corner of the module.

Product Description

Color: White + Green
Dimension: 3.2cm x 2.4cm x 1.8cm (approx)
Infrared sensor with control circuit board
The sensitivity and holding time can be adjusted
Working Voltage Range: DC 4.5V- 20V
Current drain:<60uA
Voltage Output: High/Low level signal:3.3V TTL output
Detection distance: 3--7M(can be adjusted)
Detection range: <140°
Delay time: 5-200S(can be adjusted, default 5s +-3%)
Blockade time: 2.5 S (default)
Trigger: L: Non-repeatable trigger H: Repeat Trigger (default)
Work temperature:-20-+80°C
Trigger Method: L Non-repeatable trigger / H repeatable trigger

Features:

1, the automatic sensor: to enter the sensor output range is high, people leave the sensor range of the automatic

delay off high, output low.

2,the photosensitive control (optional, factory is not set) may set the photosensitive control during the day or

light intensity without induction.

3, the temperature compensation (optional, factory is not set): In the summer when the ambient temperature rises

to 30 ~ 32 ℃, slightly shorter detection range, temperature compensation can be used as a performance compensation.

4, two trigger mode: (can be selected by jumpers)

a, can not repeat the trigger: the sensor output high, the delay time is over, the output will automatically

become low from high;

b, repeatable trigger: the sensor output high after the delay period, if the human body in its sensing range

activities, its output will remain high until after the delay will be left high to low (sensor module review

Measured activities of each body will be automatically extended after a delay time, and the final event of

the delay time Starting point of time).

5, with induction blocking time (the default setting: 2.5S block time): sensor module, after each sensor output

(high change Into a low level),you can set up a blockade followed by time period, in this time period the sensor

does not accept any sensor signal. This feature can have a "sensor output time" and "blocking time" the interval

between the work produced can be applied to detect the interval Products; also inhibit this function during load

switching for a variety of interference. (This time can be set at zero seconds - Tens of seconds).

6, the working voltage range: the default voltage DC4.5V-20V.

7, micro-power consumption: static current "50 microamps, especially for battery-powered automatic control products.

8, the output high level signals: types of circuits can be easily and docking.

Instructions:

1. Sensing module for about a minute after power initialization time, during the interval to the output module

0-3 times a minute in standby mode.

2. Should avoid direct lighting such as interference sources close the surface of the lens module so as to avoid the

introduction of interference signal generator malfunction; use of the environment to avoid the flow of the wind, the

wind sensor will also cause interference.

3. Sensor module using a dual probe, the probe's window is rectangular, dual (A per B million) in the direction of

the ends of long, when the body passed from left to right or right to left when the reach the dual IR time, distance

difference, the greater the difference, more sensitive sensors, when the body from the front to the probe or from top

to bottom or from bottom to top direction passing, dual IR not detected changes in the distance, no difference value,

the sensor insensitive or does not work; so the sensors should be installed dual direction of the probe with human

activities as much as possible parallel to the direction of maximum to ensure that the body has been passed by the

dual sensor probe. To increase the sensing range of angles, the module using a circular lens, the probe also makes sense

on all four sides, but still higher than the upper and lower left and right direction of sensing range, sensitivity and

strong, still as far as possible by the above installation requirements.VCC, trig (control side), echo (receiving end), GND

Dimensions and Adjustment:

Note: The potentiometer clockwise to adjust the distance, sensing range increases (about 7 meters), on the contrary,

sensing range decreases (about 3 meters).Delay adjustment potentiometer clockwise rotation, sensor delay longer (about 300S),

the other hand, induction by the short delay (about 5S).

5. Applications

a, Security Products

b, the human body sensors toys

c, the human body sensor lighting

d, industrial automation and control, etc.

It can automatically and quickly open various types of incandescent, fluorescent lamps, buzzer, automatic doors,

electric fans,automatic washing machine and dryer Machines and other devices,is a hightech products. Especially

suitable for enterprises, hotels, shopping malls, warehouses and family aisles, corridors and other sensitive

Sense of region, or for the security zone automatic lighting, lighting and alarm systems.
