DAOKI 2 Pcs Measuring Transducer Sensor Ultrasonic Distance Sensor Module JSNSR04T DC 5V Waterproof with 25M Cable for Arduino

Description: Specification: Electrical parameters: JSN-SR04T-2.0 Operating voltage: DC 5V Quiescent current: 5mA Total current work: 30mA Acoustic emission frequency: 40 kHz Farthest distance: 4.5m Blind: 25cm Wiring: + 5V (positive power supply) Trig (control side) RX Echo (the receiver) TX GND (negative) Module size: 41mm * 28.5mm Resolution: about 0.5cm Angle: less than 50 degrees Working temperature: -10 ~ 70 ? Storage temperature: -20 ~ 80 ? Features: 1, small size, easy to use; 2, low voltage, low power consumption; 3, high accuracy; 4, strong anti-jamming; 5, integrated with wire enclosed waterproof probe, suitable for wet, harsh measurement occasions. Application: 1, Horizontal distance; 2, obstacle avoidance, automatic control; 3, the object approaches, there is a perceived 4, traffic control; 5, security, industrial control; 6, artificial intelligence, and research The basic working principle: (1) using IO port TRIG trigger location, to the high level signal of at least 10us; (2) module automatically sends 8 40KHz Fang Bo, automatic detecting whether a signal return; (3) a signal return, a high level is output through the IO port ECHO, the time duration of the high level is ultrasonic from launch to return. The test distance = (high level time * speed of sound (340M/S)) /2. Package Included: 1 x Ultrasonic Module Distance Measuring Transducer Sensor Waterproof 2 x 4pin Dupont Cable Female to Female 2 x 4pin Dupont Cable Female to Male
