baffle and then reflects back to the probe, the TOF distance measuring method is a two-way distance measuring technology, the TOF distance measuring method mainly utilizes the time of flight between the back and forth between the signals in two asynchronous transceivers, the reflecting surface mode adopted by us, to measure the distance between nodes, in popular terms, the infrared light source is sent to the object to be measured, the light wave is collected by the sensor after being reflected by the object, the distance between the object to be measured and the camera is calculated by the

second is the detection time, because the fixed-length flight pipeline is not very long, generally about five to ten centimeters, under the distance, the time is very short relative to the propagation speed of the ultrasonic wave, generally the time is in a nanosecond range, the ultrasonic wave propagation speed is very sensitive to the change of the ammonia nitrogen concentration, the water
