Product overview Hc-sr 505 small human body induction module is an automatic control product based on infrared technology.It is widely used in automatic induction of various electrical equipment, especially battery-powered automatic control products. Technical parameters -working voltage range: dc4.5-20v -static current: 60ua -output level: high 3.3v/low 0v -trigger: repeatable trigger (default) -delay time: default: 8s+-30% (customizable range of ten ten minutes) 6. Pcb size: 10x23mm -induction angle: 100 degree cone angle -induction distance: 3 meters -working temperature:-20-+80 degrees -sensor lens size: diameter: 10mm (default) Characteristics -automatic induction: when a person enters a high range of induction output, he or she leaves the range of sensor automatically delays the closure of the high level, and the output of the low level.Super small size. 2.Remote trigger: sensor output is high, delay time, and if human activity exists within its sensing range, output will remain high level until the high variable delay of the person leaves (The last event is the starting point for the automatic extension of each activity of the sensor module to detect human delay time)。 -wide working voltage range: default working voltage dc4.5v-20v. -micro-power consumption: static current 50 micro-an, especially for battery-powered automatic control products. -output high signal: easy docking and circuitry. Application area -body induction light -human body induction toy -safety products 4. industrial automation and control 5. automatic induction of electrical equipment 6. battery automatic control Hw-ms03 Description: Output category: digital sensor Working principle: vibration sensor Sensor type: 2.4ghz to 5.8ghz radar sensor Material: mixed Norms: -not affected by temperature, humidity, airflow, dust, noise, light and dark, anti-interference, etc. -transceiver module is a field signal with wide coverage and no blind spots. -better induction during conduction: better indoor use Preventive measures: On electricity Recommended qualified power supply, i.e. output voltage, current and ripple coefficient, is standard power supply, otherwise it is a movie There may be some exceptions to the stability of the product, such as errors, newspaperlessness, automatic loop start-up, etc. About false information -see the first item to ensure that the power supply is qualified. -conduct tests to ensure that the product is not surrounded by moving objects (range of sensors) -the initial time of power supply is about 10s-30s.During this period, abnormal feelings may lead to false positive images. -during indoor testing, sensors are sensitive to the surrounding environment, need to remain static and ensure that the next cycle step test is performed before the end of the first sensor signal.Be sure to pay attention to the dynamic environment, such as birds, when testing
