Features:
1. Automatic sensor: When someone enters its sensing range is input high, people leave the sensor range is automatically delayed high. Output low.
2. Sensitive control (optional): The module is reserved for position, can be set to light control, daytime or light is not sensitive. The photosensitive control is optional and the factory does not have a photoresistor installed. If necessary, please purchase the photosensitive resistor yourself to install.
3. Two trigger modes: L can not be repeated, H can be repeated. Can be jumper selection, the default is H.
A. non-repeatable trigger mode: that is, after the sensor output high, the delay time is over, the output will automatically change from high to low.
B. repeatable trigger mode: that is, after the induction output high level, in the delay period, if the body in its induction range of activities, the output will remain high until the people leave after the delay will be high The level changes to a low level (the sensor module automatically detects a delay period after each activity of the human body and takes the last active time as the starting point for the delay time).
4. With the sensor block time (default setting: 3-4 seconds): induction module in each induction output (high level becomes low), you can set up a blockade time, in this period of time induction The device does not receive any induction signals. This function can be realized (sensing output time and blocking time) the work of the interval between the two can be applied to detect the product at the same time this function can effectively inhibit the load switching process generated by a variety of interference.
5. Wide operating voltage range: the default operating voltage DC5V to 20V
6. Micropower: static current 65 microamps, especially for dry battery-powered electrical products.
7. Output high signal: can be easily connected with various types of circuits.

Instructions for use:
1 induction module power after about a minute or so of the initialization time, at this time the module will output 0-3 times interval, a minute after the standby state.
2. should try to avoid light and other sources of interference close to the surface of the module directly to the lens, so as not to introduce interference signal generated malfunction; use the environment as far as possible to avoid
Free flow of wind, the wind will cause interference to the sensor.
3. The sensor module uses a binary probe, the probe window is rectangular, binary (A yuan B yuan) is located in the longer direction of the two ends, when the body from left to right
Or from right to left, the infrared spectrum to reach the binary time, the distance difference, the greater the difference, the more sensitive sensitive, when the human body from the front to explore.
When the head is moved from top to bottom or from bottom to top, the binary does not detect changes in the distance of the infrared spectrum, so that the sensor is not sensitive or does not work; so the sensor should be installed in the direction of the binary And the direction of human activities as much as possible parallel to ensure that the body has been passed
Probe binary inductance.
