Induction angle: not more than 15 degrees
Detection distance: 2cm-450cm
High precision: 2mm
Wiring: VCC, Trig (control side), Echo (receiving end), GND
Using IO trigger distance, the high signal to at least 10us.
Module automatically sends eight 40khz square wave, automatically detects whether a signal return;
Signal back, through the IO output a high electrical level, high electrical level duration is: the ultrasound time from launch to return.
Test distance = (time of the high electrical level * speed of sound (340M / S)) / 2;
Package Included :
1pcs x Ultrasonic Module HC-SR04 Distance Measuring Transducer Sensor for Arduino HCSR04 DC 5V IO Trigger Sensor Module HC SR04 Board
HC-SR04-P is a wide range of ultrasound working voltage measuring module distance.
Module size and software is fully compatible with the old HC-SR04 version. It can be perfectly interrupted with the old HC-SR04 version.
Low to 3V minimum operating voltage, so that it can be directly connected to the 3.3V powerMCU.
High operating voltage: 3 V-5.5 V
With software and hardware HC-SR04 size is fully compatible
5 V: 2 cm-450 cm
3.3 V: 2 cm to 400 cm
Detection angle: <15
Use of industrial grade MCU, operating temperature: -20-80 degrees Celsius
1: This module does not have to be charged connection, if you want to live connection, then let the Gnd module end connection first. Otherwise it will affect the form's work.
2: When they go, the area of the measured object is not less than 0.5 square meters, and to be as easy as possible.
3: If the test surface is irregular or remote test objects, multiple measurements can be used to correct it.
