Feature 1 Handy Size: The ultrasonic ranging sensor module has a small size, which is convenient for people to carry and use in most scenes. The small size achieves low consumption, the working current8MA(5V power supply). 2 Adaptive Performance: The ultrasonic ranging sensor module is made of thermoplastic ABS material, which give the module a firm shell, comes with a strong adaptive ability. The module is waterproof, dust resistance, and can be used in wet and harsh measurement situations. 3 High Accuracy: Built in high accuracy ranging algorithm gives the module high accuracy. Intelligent sighal adoption lessens the blind area. Automatic correction of temperature deviation make a stable ranging. 4 Main Application: With a waterproof shell. This sensor is suitable for outdoor applications such as car reversing sensors, security alarms, industrial inspection, etc. 5 Range Scale: The ultrasonic ranging sensor module can work from minus 15 celsius to 60 celsius, accurately sensing the distance within 28450CM.Item Type: Ultrasonic Ranging Sensor Module Material: ABS, PCB Range Scale: Approx 28-450CM/11in-177.2in Work Temperature: 15 Package List1 x Module2 x Sealing Rings
