WMYCONGCONG 10 PCS HC-SR04 Ultrasonic Distance Measuring Sensor Module for Arduino
WMYCONGCONG 10 PCS HC-SR04 Ultrasonic Distance Measuring Sensor Module for Arduino
Specification: Voltage: DC 5V The static current: less than 2mA Level of output: high 5V, low 0V Sensor angle: less than 15 degrees Detection distance: 2cm-450cm Precision: up to 3mm Weight: about 8.4g Size: 452015mm/1.770.780.59in Connection: VCC, trig(control end), echo(receive terminal), GND(Connect to Ground) Working principle: 1. Adapting IO trigger range, at least 10 us high level signal. 2. Module automatically sent eight 40 KHZ square wave, automatically detect whether there is signal to return. 3. Have signal returned, output high level through the IO, the duration of the high level is Ultrasonic from launch to return time. Test distance = (high level of time sound velocity (340 m/S)) / 2. Package included: 10pcs HC-SR04 ultrasonic measuring sensor module
