2Pcs JSN-SR04T Integrated Distance Measuring Sensor Ultrasonic Module Waterproof JSN-SR04T-V3.0

Operating voltage: DC3.0V to 5.5V Operating current: less than 8mA Detection frequency: 40kHz Maximum range: 500cm Nearest range: 21cm Measuring angle: 75° Beam angle: less than 50° Static current: 5mA Current consumption: 30mA Trigger signal: TTL pulse above 10 microseconds, serial port sends 0X 55 command Echo signal output: Output pulse width or TTL signal level Wiring type: for positive power supply 3-5.5V, Trig(RX) RX, Echo(output) TX and negative power supply GND Operating and storage temperature: -20°C to +70°C Working Principle: The JSN-SR04T has a transducer that is connected via a 2.5m cable. These sensor modules are divided into 2 separate parts, the transducer and the control board. The transducer works according to the simple formula given below: Distance = Velocity x Time Ultrasonic waves are emitted by an ultrasonic transmitter. This ultrasonic wave travels through the air and whenever it is blocked by any object/material, it is reflected back to the transducer and this reflected wave is observed and measured by the ultrasonic receiver module is observed and measured. The distance is now measured using the above equation and known values of velocity and time. The common propagation speed of ultrasonic waves at room temperature is 330m/s. This circuit is built into the module and is used to calculate the time it takes for the ultrasonic wave to return while the return pin is set high, which helps to understand how long the process takes. The distance is calculated by using a microprocessor/microcontroller. Package include: 2 x JSN-SR04T ultrasonic distance measuring sensor module
