Description There are many ultrasonic ranger module on the market, but sometimes, these kind of sensor needs to work in conditions more than the Lab. This water proof ultrasonic sensor meets this requirement. It has a good performance and almost the same usage like HC-SR04 module. Technical Specifications Electrical parameters: JSN-SR04T Operating voltage: DC 5V Quiescent current: 5mA Total current work: 30mA Acoustic emission frequency: 40khz Farthest distance: 4.5m Blind: 25cm Module size: 41mm * 28.5mm Resolution: about 0.5cm Angle: less than 50 degrees Working temperature: -10 ~ 70 ℃ Storage temperature: -20 ~ 80 ℃ Pinouts VCC : 5V (positive power supply) trig(T) : Trigger Input echo(R) : Echo Output GND Documents and Downloads Arduino Example Code for HC-SR04 but also works with JSN-SR04T – Water-proof Ultrasonic Module Distance Measuring Sensor Package Includes 1x JSN-SR04T – Water-proof Ultrasonic Module Distance Measuring Sensor
