DollaTek DC 5V waterproof ultrasonic distance sensor, which measures the measuring converter with 2.5m cable for Arduino

Description: This module uses the simple method, a control port with 10US above the high level, which can wait for the high-output in the receiving sport. An output can control the timer. If this port is low, the timer value can be read, where this time for the place of time can calculate the distance. So continuous cycle test that can reach the measurement of the value of your mobile phone. Specifications: Operating voltage: DC 5 V. Rest current: 5mA. Furthest distance: 4.5 m. The device is waterproof, but cannot work under water. Please note: High accuracy, strong interference, small size, easy to operate, low voltage, low power consumption. Integrated with waterproof probe, suitable for wet, rough blade sessions. What you get: 1 x DC 5V Waterproof Ultrasonic Distance Sensor Measuring Range Converter Module with 2.5m Cable for Arduino
