Description

HC-SR04 HC SR04 Arduino Ultrasonic Sensor

 

HC SR04 Ultrasonic Sensor is also called HC- SR04 Ultrasonic Range Finder. This ultrasonic sensor module HC-SR04 range is 2cm- 400cm and it is non-contact measurement function. This module accuracy can reach to 3mm. this sensor includes ultrasonic transmitters, a receiver, and a control circuit. This ultrasonic sensor uses sonar to find the distance. Dolphins and bats also follow this procedure. It provides stable reading and it is easy to use packages. Its range is almost 1 to 13 feet. it consists of 4 pins. Trigger (Trig), Echo (Receiver), VCC (Power), and Ground (GND). Trigger pin used for transmitting the signals. The echo pin receives the signal which comes back. VCC pin used to power up the sensor. and the GND pin is just for the ground pin.  This sensor also has a positive point that the ultrasonic sensor does not affect by sunlight or black material like sharp rangefinders. This HC-SR04 sensor can easily interface able for many microcontrollers, for example, Arduino UNO R3, Microchip PIC, and ST Microcontrollers. Get that sensor at epro.pk.

 

The value of Speed of Sound = v = 340 m/s OR 0.034 cm/us.

The TIME formula is = T = s/v = 10 / 0.034 = 294 us.

Then,

The DISTANCE formula is = s = t * 0.034 / 2.
