ขาย โมดูลอัลตราโซนิก hc - sr 04 เซนเซอร์วัดระยะทาง transducer สําหรับ arduino ราคาที่ดีที่สุด

Features: Supply module with 5V the output will be 5V while obstacle in range or 0V if not. The out pin of this module is used as a switching output when anti-theft module and without the feet when ranging modules. Adopt IO trigger through supplying at least 10us sequence of high level signal. The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal. If there is signals returning through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving. Test distance = (high level time * sound velocity (340M/S) / 2. Specification: Work Voltage: DC 5V Static Current: <2mA Level Output: 0-5V Sensor Angle: ≤15 degree Detecting Distance: 2-450cm Included: 1 X HC-SR04 Module #toolgadget #transducersensor #UltrasonicModule #forArduino #ConsumerElectronics #DistanceSensor #DistanceMeasuringModule #Module #MeasuringTools #DistanceModule #DistanceMeasuringTransducerSensor #UltrasonicDistanceMeasurementModule #MotorsDrive #BusinessIndustrial #HC-SR04Module #Ultrasonic
