Ximimark 1Pcs JSN SR04T Integrated Ultrasonic Module Ultrasonic Distance Measuring Transducer Sensor Waterproof DC 5V

Electrical performance: Lead length: 2.5M Operating voltage: DC 5V Quiescent current: 5mA Total current work: 30mA Acoustic emission frequency: 40khz Farthest distance: 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 ¡ãC Storage temperature: -20 ~ 80 ¡ãC Basic working principle: Use IO port TRIG to trigger ranging, giving a high level signal of at least 10us; The module automatically sends eight 40khz square waves to automatically detect whether there is a signal return; There is a signal return, a high level is output through the IO port ECHO, and the high level duration is the time from the transmission to the return of the ultrasonic wave. Test distance = (high time * sound speed (340M / S)) / 2; Note: The installation of electronic modules requires basic knowledge and requires a certain electronic professional foundation and hands-on ability. Please purchase carefully! Manual measurement, with small error. Please check size in detail before purchase. Real colors may slightly differ from the pictures, as it depends on specific monitor settings and light brightness.
