Ultrasonic Sensor (HC-SR04) – Overview
The HC-SR04 ultrasonic sensor is commonly used in robotics and automation to measure distances. It works by emitting ultrasonic waves and measuring the time taken for the echo to return.
Technical Specifications:
| Feature | Details |
|---|---|
| Operating Voltage | 5V |
| Operating Current | 15mA |
| Measuring Range | 2 cm – 400 cm |
| Accuracy | ±3 mm |
| Operating Frequency | 40 kHz |
| Trigger Input Signal | 10µs TTL pulse |
| Echo Output Signal | TTL (High when echo detected) |
Pin Description:
| Pin | Function |
|---|---|
| VCC | Power Supply (5V) |
| GND | Ground |
| Trig | Trigger Input (Send Signal) |
| Echo | Echo Output (Receive Signal) |
How It Works:
- The Trig pin is set HIGH for 10µs to send an ultrasonic pulse.
- The pulse travels and bounces off an object.
- The Echo pin receives the reflected signal.
- The Arduino calculates distance using the time delay.
Formula for Distance Calculation:
Distance=Time×Speed of Sound2\text{Distance} = \frac{\text{Time} \times \text{Speed of Sound}}{2}
(Speed of sound = 343 m/s or 0.034 cm/µs)
Arduino Connection:
| HC-SR04 | Arduino Uno |
|---|---|
| VCC | 5V |
| GND | GND |
| Trig | Pin 9 |
| Echo | Pin 10 |
