This ultra ranging sensor is a non-contact distance measurement module with stable performance and high ranging accuracy, featuring a smaller blind zone, wider sensing angle, and certain penetration power compared to similar sensors. It can detect the distance between the ultra wave and the target. Widely used in robot obstacle avoidance, parking management systems, and automatic control applications. Average Current: Less than 8mA Response Time: 100ms Detecting Range (Flat object): 3-450cm Operating Temperature: -15°C to 60°C Reference Angle: 60º Waterproof Grade: IP67 Measurement Accuracy: ±(1 + S*0.3%) Type: PWM pulse width / UART serial port / RS485 Color: Black Material: Plastic Package Contents: 1 x Ultra Ranging Sensor Note: Light reflection and different displays may cause slight color variations between the item in the picture and the actual product. The measurement allows an error of +/- 1-3cm.
