Features:
- HC-SR501 is an automatic control module based on infrared technology, using LHI778 probe design, high sensitivity, strong reliability, ultra-low voltage working mode, widely used in all kinds of automatic induction electrical equipment, especially automatic control products powered by dry battery.
- Automatic induction: When someone enters its induction range, enter the high level, people leave the sensor range is automatically delayed off high. Output low.
- Photosensitive control (optional): The module reserved for location, can be set to photosensitive control.
- Two trigger modes: L is not repeatable, H is repeatable. Can be jumper selected, the default is H.
- Induction blocking time (default setting: 3 - 4 seconds): After each sensing output (high level goes low), the sensing module can be followed by a blocking time, during which it is sensed The device does not receive any sense signals. This function can be used to achieve the interval between the sensing output time and the blocking time. It can be applied to the interval detection products. At the same time, this function can effectively suppress all kinds of interference in the process of load switching.
- Micro power: Quiescent current 65mA, especially for dry battery-pow
