Ultrasonic Robot Obstacle Avoidance Sensor Module Pulse Width Distance Sensor IP67 PWM DC3.3-12V Function: 1. Output: the ultrasonic distance module has a built-in low power consumption design, according to the actual use, the power consumption can be reduced to a minimum, the blind area is less than 2cm.2. Detection Angle and Is Not Affected: The ultrasonic distance module is suitable for a variety of application environments, which is not affected by the color, transparency, material (metal, non-metal) caused by the detection object, large FOV detection angle, measurement angle from 30 to 60 deg;.3. IP67 Protection: The robot's obstacle avoidance sensor is IP67, waterproof, dustproof and oil-proof, designed based on robot automatic control, with fast response time and same-frequency interference filtering.4. Heterodyne acoustic wave processing: The obstacle avoidance sensor has heterodyne acoustic wave processing technology to output FFFE data to indicate the existence of homodyne interference when detecting the existence of homodyne interference in the environment.5. Suitable scenario: ultrasonic distance measurement module is suitable for battery power supply, short or long distance USB power supply, switching power supply and high noise power supply.6. Wide Application: Obstacle avoidance sensor has a wide range of applications, suitable for various scenarios of object proximity and existence detection, parking management system, robot obstacle avoidance, automatic control, etc. Specification: Item type: ultrasonic distance measurement sensor Material: ABS Measurement accuracy: (1 +S x 0.3%) Working voltage: DC3.3V-12V Blind area distance: 2cm(0.8in) Output response time: le; 15ms Output Mode: PWM Pulse Width Temperature Compensation: Yes Plane Range: 2-300cm(0.8-118.1in) Application: Robot Obstacle Avoidance, Intelligent Garbage Bin Detection, Parking Space Detection, Smart Home etc. Package List: 1 x Ultrasonic Distance Sensor How to use z:Install and use.
