Features:
1. Automatic induction: When someone enters the induction range, the sensor input is high. Those leaving the sensor range are automatically held high. The output is low.
2. Photosensitive control (optional): The module is designed for placement and can be set for photosensitive control. Strong light during the day or without induction. The photosensitive control is optional; the factory does not install a photosensitive resistor. If necessary, please purchase a separate photosensitive resistor for installation.
3. Two trigger modes: L (non-repeatable) and H (repeatable). A jumper can be selected, but the default is H.
A. Non-repeatable trigger mode: The induction output is high, the delay time expires, and the output automatically changes from high to low.
B. Repeated trigger: That is, after detecting a high output, during the delay period, if the human body is in its sensing range, the output will remain high until the delay period ends. After the human body leaves the high level, the output changes to low. (The sensing module automatically delays the delay after each human body activity and uses the time of the last action as the starting point of the delay time.)
4. Induction lockout time (default setting: 3-4 seconds): After each sensing output (high level goes low), the sensing module can be followed by a lockout time, during which the device does not receive any audible signals. This function can be used to achieve the interval between the sensor output time and the locking time. It can be applied to interval detection products. At the same time, this function can effectively suppress all types of interference during the load switching process.
5. Wide operating voltage range: The default operating voltage is 5V to 20V DC.
6. Micropower supply: 65μA current, especially for battery-powered dry electrical products.
7. High-level signal output: Can be easily coupled with various circuit types.
Instructions for use:
1. Power the induction module for about one minute after the initialization time. During this time, the module will output 0-3 times per minute, and 1 minute in standby mode.
2. Avoid direct light and other interference from directly covering the lens module surface to avoid signal interference and malfunction. Use the surrounding environment as much as possible to avoid free-flowing wind, as wind will interfere with the sensor. 3. A sensor module with a dual-element probe. The probe window is rectangular, with dual elements (A yuan B yuan) in the longer direction at both ends when the body is oriented from left to right.
