Ultrasonic Ranging Waterproof Integrated Module JSN B02 V2.0
Are you in need of a distance sensor that used for outdoors? This ultrasonic sensor fits that requirement. Though this sensor is the same way as HC-SR04 ultrasonic sensors, this one is more accurate. It is 5V operated, but it only needs 30mA current. It only needs 4 wire from your Arduino board; +5V (positive), Trig (control), Echo (receive), and GND (cathode). It also has screw holes for easier mounting. You may use this sensor for distance measurement, obstacle avoidance, traffic control, and others. This ultrasonic sensor has a waterproof probe, but its circuit isn't.
The cord is PVC protected and around 1 meter in length.
