Description:

1. Fully automatic sensing: When someone enters its sensing range, it will input high level, and when the person leaves the sensing range, it will automatically delay and turn off the high level and output low level.
2. Photosensitive control (optional): The module has a reserved position, and can set light-sensitive control. It does not sense during the day or when the light is strong. Photosensitive control is an optional feature and no photo-resistor is installed at the factory. If necessary, please purchase a separate photoresistor and install it by yourself.
3. Two trigger modes: L can not be repeated, H can be repeated. Jumper wire selection, default is H.
A. Non-repeatable trigger mode: After the sensor output is high, once the delay time expires, the output will automatically change from high to low.
B. Repeatable trigger mode: After the sensor output is high, during the delay period, if the human body is active in its sensing range, the output will remain high level until the person leaves and changing to a low level (the sensing module automatically delays one delay period after detecting each activity of the human body, and the time of the last activity is the starting point of the delay time).
4. With sensor block time (default: 2.5s): The sensor module can set a blocking time immediately after each sensor output (high level becomes low level). During this period, the sensor does not receive any sensing signal. This function can realize the interval work between inductive output time and block time and can be applied to the interval detection product; at the same time, this function can effectively suppress various interferences generated during load switching.
5. Wide operating voltage range: default operating voltage DC5V to 20V
6. Micro power consumption: 60 microamps quiescent current, especially suitable for dry battery-powered electrical products.
7. Output high level signal: It can be easily connected with various circuits.
8. Wide Application：Security Products；Human Body Sensing Toys；Human Induction Lamps；Industrial Automation Control，etc
It can automatically turn on various types of incandescent lamps, fluorescent lamps, buzzer, automatic doors, electric fans, dryers and automatic washing machines. It is especially suitable for sensitive areas such as aisles and corridors of enterprises, hotels, shopping malls, warehouses and families, or automatic lighting and alarm systems for safe areas

Instructions for use:
1. The initialization time of the sensor module is about one minute after the power is on. During this period, the module will output 0-3 times at intervals and will enter the standby state after one minute.
2. Avoid direct interference from sources such as lights to the lens on the surface of the module and try to avoid the flow wind, the wind will also cause interference to the sensor
3. The sensor module uses dual elements probes. The window of the probe is rectangular. The dual element is located at both ends of the longer direction. When human walks from left to right or from right to left, there is a difference in time and distance that the infrared spectrum reaches the dual element. The greater the difference, the more sensitive the sensing. When human walks from the front to the probe or from top to bottom, the dual element won't detect the change of the infrared spectrum distance, and there is no difference. Thus the sensor is not sensitive or not working. When installing the sensor, make sure the direction of probe dual element and the direction of human activities as parallel as possible, to ensure that the human body has been induced by the dual element.
