4PCS JSN-SR04T Waterproof Ultrasonic Distance Measuring Module Integrated with Wires Compatible with Arduino

Name: JSN-SR04T Ultrasonic Distance Measuring ModuleWorking Voltage: DC 5VStatic Working Current: 5mATotal Working Current: 30mASound Wave Emission Frequency: 40KHzMaximum Measurement Distance: 5m / 16.4ftBlind Zone: 25cm / 0.98inWiring Method:+5V (Power Positive)；Trig (Control Pin) RX；Echo (Receive Pin) TX；GND (Power Negative)Electrical Performance: Lead length is 2.5m / 8.2ftModule Dimensions: 41mm (L) × 28.5mm (W) / 1.61in × 1.12inResolution: Approximately 0.5cmAngle: Less than 50 degreesWorking Temperature: -10 to 70℃Storage Temperature: -20 to 80℃Working Principle:1、Use the IO pin TRIG to trigger distance measurement by sending a high-level signal of at least 10us.2、The module automatically sends 8 pulses of 40kHz square waves and detects whether a signal is returned.If a signal is returned, the IO pin ECHO outputs a high level; the duration of the high level indicates the time taken for the ultrasonic wave to travel to the object and back. The measured distance = (high level time × speed of sound (340M/S)) / 2.3、Usage: Send a high-level signal of more than 10us from a control pin, then wait for a high-level output at the receiving pin. Start a timer as soon as an output is detected. When the receiving pin goes low, read the timer's value; this value represents the time taken for distance measurement. Using the formula, the distance can be calculated. By continuously cycling this process, you can obtain the required measurement values.
