Miniature human body infrared sensor module PIR infrared pyroelectric sensor/Fresnel lens/induction switch probe AS312-64305
product detail
AS312:
Product Features:
1. Low power consumption, small size, easy to install
2. Internal use of digital signal processing, pit interference strong
3. High sensitivity, reliability, and can be widely used in automatic sensing circuit
4. Repeatable trigger mode: that is, after the induction output is high, in the delay period, if the body in its induction range of activities, the output will remain high until the delay after the person to become Low level. (Ie, the sensing 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).

HC-SR505:
Product Overview:
HC-SR505 small body sensing module is based on infrared technology, automatic control products, high sensitivity, high reliability, ultra-small, ultra-low-voltage operation mode. Widely used in various auto-sensing of electrical equipment, especially battery-powered automatic control products.
Technical parameters
1. Operating Voltage Range: DC4.5-20V
2. Static current: <60uA
3. Output level: High 3.3V / Low 0V
4. Trigger: repeatable trigger (default)
5. Delay time: Default 8S + -30% (can be customized range of a few tenths - tens of minutes)
6. PCB Dimensions: 10 * 23mm
7. Induction angle: <100 degree cone angle
8. Induction distance: 3 meters
9. Working temperature: -20 - +80 degrees
10. Sensor Lens Dimensions: Diameter: 10mm (default)
Features
1. Automatic induction: to enter the sensing range of the output is high, people leave the sensor range automatically delay off high, output low. Ultra-small size.
2. Repeatable trigger: the sensor output high, the delay period, if there is human activity in its sensing range, the output will remain high until people leave after the high variable delay (automatically extended sensor module detects the human body after every activity a delay period, and the last time an event is the starting point of the delay time).
3. Wide operating voltage range: the default operating voltage DC4.5V-20V.
4. Micropower: quiescent current < 50 microamps, especially for battery-powered automatic control products.
5. Output high signal: easy docking and all kinds of circuits.
Applications:
1.Body induction lamps
2.Body sensors toys
3.Security Products
4.Industrial automation and control
5.Auto-sensing of electrical equipment
6.Battery-powered automatic control

Instructions For Use:
1. After the module is powered on, there is a initialization time of about one minute. At this time, the module will output 0~3 times at intervals, and enter the standby state after one minute.
2. Try to avoid the interference of the light source and other sources directly on the surface of the module, so as to avoid the introduction of interference signals and malfunction. Avoid the wind, the wind will also interfere with the sensor,
3. The sensing module uses a dual-element probe, the window of the probe is rectangular, and the dual element (A-B element) is located at both ends in the longer direction, when the human body is from left to right.
Or when going from right to left, the infrared spectrum reaches the binary time and the distance has a difference. The larger the difference, the more sensitive the induction is. When the human body moves from the front to the probe or from top to bottom or from bottom to top, The binary check does not change the infrared spectral distance, there is no difference, so the induction is not sensitive or does not work, so the sensor should be installed so that the direction of the probe dual is as parallel as possible in the direction of the human body. Ensure that the human body is inductively detected by the probe.
