【HC-SR505】HC-SR505 small body detection module is based on infrared technology, automatic control products, high sensitivity, high reliability, ultra-small and ultra-low voltage operating mode. Widely used in various automatic sensors of electrical equipment, especially battery-powered automatic control products. 【Compact Design】Operating voltage range: DC4.5-20V; Static Current: <60uA; Output Level: High 3.3V/Low 0V; Trigger: repeatable trigger (default); Delay time: default 8S + -30% (you can customize the range of a few tenths - tens of minutes). 【Simple Operation】Induction angle: 100 degree cone angle; Induction distance: 3 meters; Working temperature: -20 - +80 degrees; Sensor Lens Size: Diameter: 10mm (default). If there is human activity within its detection range, the output will remain high until people leave after the high variable delay. 【Compatible】Wide operating voltage range: default operating voltage DC4.5V-20V. Micropower: quiescent current <50 microamps, especially for battery-powered automatic control products. High signal output: easy pairing and all types of circuits. 【High Performance】Automatic induction: to enter the sensing range of the output is high, people leave the sensor range automatically delaying the high, output low. Ultra small dimensions. Repeatable Trigger: The sensor output is high, delay period, if there is human activity in its sensing range, the output will remain high until people leave after a high variable delay., Weight: 0.0440924524 pounds, Manufacturer: TECNOULAB
