About this item

• •Specification
• •Electrical parameters: JSN-SR04T
• •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
• •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;
• •This module uses the simple method, a control port with a 10US above high level, can wait for high level output at the receiving port. An output can drive the timer, when this port is low can read the timer value,
• •this time for the location of the time, can be calculated distance. So constantly cycle test, that can achieve the measurement of the value of your mobile.
• •Package Included:
• •2* JSN-SR04T Ultrasonic Distance Measuring Transducer Sensor Waterproof
