The small human body induction module is an automatic control product based on infrared technology, known for its high sensitivity, strong reliability, ultra-small size, and ultra-low voltage operation mode. It is widely used in various automatic sensing electrical devices, especially those powered by batteries.

Features:

• Automatic Sensing: When a person enters the sensing range, the module outputs a high-level signal. When the person leaves the sensing range, it automatically delays and turns off the high-level output, switching to a low-level signal.
• Repeatable Trigger Mode: After the module outputs a high-level signal if a person moves within the sensing range during the delay period, the output will remain high until the person leaves, at which point the high-level output will delay and then switch to low-level. Each detected movement within the sensing range resets the delay period, starting from the last detected movement.
