HiLetgo Analog Current Meter Sensor Module AC 0~5A Ammeter Sensor Board Based on TA12-100 for Arduino

Operating Principle -- Ultrasonic hc-sr04 distance measuring transducer sensor, it consists of ultrasonic transmitter, receiver, and control circuit..
HC-SR04 ultrasonic sensor module -- Using IO trigger for at least 10us high level signal, when triggered it sends out a series of 40KHz ultrasonic pulses and receives echo from an object, the duration of the signal is the time from sending ultrasonic to returning..
Test Distance Formula -- The distance between the unit and the object is calculated by measuring the traveling time of sound and output it as the width of a TTL pulse,hc-sr04 test distance following formula -- L = 1/2 × T × C ( L is the distance, T is the time between the emission and reception, and C is the sonic speed ).
Package Include -- 5 X HC-SR04 Ultrasonic Sensors , 10 X Female-Male Dupont Cables , 10 X Female-Female Dupont Cables , 3 X HC-SR04 Mounting Bracket.
