Basic working principle:

• (1) Use IO port TRIG to trigger distance measurement and give a high-level signal of at least 10us.
• (2) The module automatically sends 8 40khz square waves, and automatically detects whether there is a signal return.
• (3) When there is a signal return, a high level is output through the IO port ECHO, and the duration of the high level is the time from the ultrasonic wave to the return. Test distance = (high level time * speed of sound (340M/S))/2;

• Current Consumption: 15mA
• Ultrasonic Frequency: 40 kHz
• Measuring Range: 2 cm to 400 cm
• Resolution: 0.3 cm
• Measuring Angle: 15 degrees
• Trigger Input Signal: 10µs TTL pulse
• Echo Output Signal: TTL signal proportional to the distance
• Dimensions: 45mm x 20mm x 15mm

Pin Configuration

• VCC: 5V power supply input
• GND: Ground
• Trig: Trigger input pin
• Echo: Echo output pin

Features

• Accurate Distance Measurement: Provides reliable distance measurement from 2 cm to 400 cm.
• Easy to Interface: Can be easily interfaced with various microcontrollers using the trigger and echo pins.
• Compact Size: Small form factor allows for easy integration into projects.
