Specification:
Brand new and high quality.

Technical Parameters:
1. Operating voltage: DC5V to 20V
2. Static power consumption: less than 60 microamps
3. Level output: 3.3V high, low 0V
4. Delay time: adjustable (0.3 seconds to 18 seconds)
5. Block time: 2.5 seconds
6. Trigger mode: L can not be repeated, H can be repeated, the default value of H
7. Sensing range: less than 120 degrees cone angle, less than 7 meters
8. Operating temperature: -15 ~ +70 degrees
9.PCB Dimensions: 32 * 24mm, screw hole from the 28mm, screw diameter 2mm, sensor lens size: (diameter): 23mm (default)

Features:
1. Automatic sensor: When someone enters the induction range, enter the high level, people leave the sensor range is automatically delayed high. Output low.
2. Sensitive control (optional): The module is reserved for location, 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 sensing 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 time period after each activity of the human body, and takes the last active time as the starting point of the delay time).
4. With the sensor block time (default setting: 2.5 seconds): sensor module in each induction output (high level becomes low), you can set up a blockade time, in this period of time sensor does not Receive any induction signal. This function can be implemented (interval between sensing output time and block time), which can be applied to interval detection products. This function can effectively suppress various disturbances generated during load switching.
5. Wide operating voltage range: the default operating voltage DC5V to 20V
6. Micropower: quiescent current 60 microamps, especially for battery-powered electrical products.
7. Output high signal: can be easily connected with the various types of circuits.



Applications:
Pyroelectric infrared switch is BISS0001 with pyroelectric infrared sensor and a small amount of external components composed of passive infrared switch. It can automatically open all kinds of incandescent, fluorescent, buzzer, automatic doors, fans, dryers and automatic washing machines and other devices, is a high-tech products. Particularly applicable to enterprises, hotels, shopping malls, warehouses and family aisle, corridors and other sensitive areas, or for safe areas of automatic lighting, lighting and alarm systems.

Instructions for use:
1. After the induction module is energized for about one minute, the module will output 0-3 times at intervals, and enter the standby state after one minute.
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 to produce malfunction; use the environment to avoid the flow of wind, the wind will interfere with 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 The greater the difference between the distance, the more sensitive, when the human body from the front to the probe or from top to bottom or from bottom to top direction, the binary detection of infrared spectral distance changes, no difference Value, so the sensor is not sensitive or does not work; so the sensor should be installed in the direction of the dual direction of the probe with the direction of the human body as much as possible parallel to ensure that the human body has been tested by the binary sensor. In order to increase the scope of the induction angle, the module uses a circular lens, but also makes the probe on both sides of the sensor, but the left and right sides are still higher than the upper and lower direction of induction, sensitivity, installation must be as much as possible.
