New HC-SR501 Sensor Module pyroelectric sensor + 5V Channel Relay Module PIC ARM Good

HC-SR501 Sensor Module pyroelectric sensor:

Electrical parameters:
Product Type: HC--SR501 Body Sensor Module
Operating voltage range: DC 4.5-20V
Quiescent Current: <50uA
Level output: High 3.3 V /Low 0V
Trigger: L can not be repeated trigger/H can be repeated trigger(Default repeated trigger)
Delay time: 5-200S(adjustable) the range is (0.xx second to tens of second)
Block time: 2.5S(default)Can be made a range(0.xx to tens of seconds
Board Dimensions: 32mm*24mm
Angle Sensor: <100 ° cone angle
Operation Temp: -15-+70 degrees
Lens size sensor: Diameter:23mm(Default)

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 seleced 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
