- Compact blue PCB: 50 x 90 x 6mm, 20g
- Ideal for robotics, obstacle avoidance, parking sensors, liquid-level detection, and embedded projects
Specifications:
- Operating voltage: 3V-5.5V
- Working current: 5mA
- Working frequency: 40Hz
- Detection distance: 2cm-450cm at 5V / 2cm-400cm at 3.3V
- Detection angle: less than 15
- Trigger input: 10 s TTL pulse
- Echo output: TTL level signal, proportional to range
- PCB dimensions: 50 x 90 x 6mm
- Weight: 20g
- Working temperature: -20 C to 80 C
Built around an industrial-grade MCU with an integrated receiver and transmitter on a single blue PCB, this module offers reliable, precise distance measurement in a compact form factor.
Fully compatible with Arduino, Raspberry Pi, ESP32, and other 3.3V or 5V microcontroller platforms - simply swap it in without modifying existing hardware or software.
