    Passive infrared (PIR) Motion sensor module (HC-SR501, LH1778)

    Passive infrared (PIR) Motion sensor module (HC-SR501, LH1778)


    Passive infrared (PIR) Motion sensor module (HC-SR501, LH1778)

    Feature

    This is a motion detector sensor module base on passive infrared emitted by the human body or animal. The module designed using LHI778 chipset with high accuracy and reliability as well as low power. It can be powered by battery for all day long.

    Note 1: For Mode L (occur once), the module will output high logic if trigger. After a certain delay time (adjustable), the module stays low logic forever.

    Note 2: For Mode H (repeat),  the module will output high if trigger. If there is any movement after a certain delay time (adjustable), the module will stay on high logic until another delay time.

    Note 3: The module locks up time trigger when the sensor change from high to low logic. Within this time, the module will not react to any movement.

    Note 4: Two potentiometers are used to tune the module sensitivity (near the jumper) and the delay time. Clockwise tuning increase the sensitivity and delay time and vice versa.   

    Note 5: Initialize procedure take 1 min after the module power-up. Do not take the measurement within this time frame.

    Note 6: Any active light source or wind will interfere with this module.
