The URM37 Ultrasonic Distance Sensor is a compact non-contact measurement module that uses ultrasonic waves to detect how far an object is. With a working range of 2-800cm and both RS232 and UART output options, it is a popular choice for makers, students, and engineers building robotics, automation, and smart monitoring projects. It suits home tinkerers, school and university projects, and small automation setups that need reliable distance readings without touching the target.
Key features
- Ultrasonic distance measurement over a wide 2-800cm range.
- RS232 and UART output for easy connection to microcontrollers and computers.
- Non-contact sensing, so no wear on moving or fragile targets.
- Compact module that fits neatly into robotics and DIY builds.
- Commonly compatible with Arduino, Raspberry Pi, and similar boards.
Typical uses
- Obstacle detection and navigation for robots.
- Level sensing in tanks and containers.
- Object presence and distance monitoring in automation projects.
- Educational electronics and prototyping experiments.
How to choose / tips
- Confirm your board supports UART or RS232 so wiring is straightforward.
- Mount the sensor facing the target with a clear line of sight for best results.
- Keep the sensor away from heavy vibration and direct splashing for steady readings.
