ITEM NAME:JSN-SR04T Ultrasonic Module Distance Measure Transducer Sensor Waterproof TTD Descriptio n Material: RF4+ plastic Color: picture color Size: 41*28.5mm wire length 1 m Weight: 0.043 kg Electrical performance: Electrical parameters: jsn-sr04t Working voltage :DC 5V Static current :5 The total current: 30 ma Acoustic emission frequency :40khz Maximum distance :4.5 m Blind :25 cm Wiring mode :+ 5V(positive power supply) Trig function (control side)RX Echo receiver Ground (negative) About half a centimeter Angle: less than 50 degrees Operating temperature :-10 ~ 70℃ Storage temperature :-20 ~ 80℃ Product features: 1, small size, easy to use; 2. Low voltage, low power consumption; 3. High precision; 4. Strong anti-interference ability; 5, built-in wire sealing waterproof probe, suitable for wet, bad measurement occasions. Application: 1. Horizontal distance; 2. Obstacle avoidance and automatic control; 3. As objects approach, there is a sense of perception 4. Traffic control; 5. Safety and industrial control; 6. Artificial intelligence and research Basic working principle: (1) IO port triangular-trigger positioning, at least 10us for high level signals; (2) the module automatically sends 8 40KHz square waves and automatically detects whether there is any signal to return; (3) when a signal returns, a high level is output through IO port echo, and the duration of the high level is Ultrasonic wave from emission to return.Test distance =(high level time * sound velocity (340 m/s))/2; The module USES a simple method, a control port with high level above 10US, can wait for high level The output of the receive port.An output can drive the timer, and when the port is low the timer value can be read, This time for the time of the position, you can calculate the distance.So you just keep testing and you can do it Measure the value of your phone.
