The mode as follows 1, basic working principle: (1)use IO port TRIG to trigger ranging, and present high-power level signals with a minimum of 20US. (2)the module automatically sends 8 square waves of 40kHz to automatically detect whether there is a signal return; (3)if there is a signal, ECHO outputs a high level through the IO port. The duration of the high level is the time when the ultrasonic wave returns from sending it. Test distance = (high level Time * sound velocity (348M/S))/2; (4) after the module is triggered for distance measurement, if no ECHO is received (the reason is beyond the measured range or the probe does not face the measured object), the ECHO Port will automatically become low after 40ms, marks the end of this measurement, whether successful or not. 2Ultrasonic timing diagram: figure II,ultrasonic timing 12:Mode=47KUARTautomatic output UARTthe automatic output mode outputs the distance value (hexadecimal number) according to UART Communication Format.

Triode drive relay should be added during application. If there are special requirements to modify the threshold value or other settings, special instructions are required when purchasing.

JSN-SR0T4-V3.0 ultrasonic ranging module can provide 21cm-600cm non-contact distance sensing Function, ranging accuracy can be as high as 3mm; the module consists of an ultrasonic sensor and control circuit integrated with transceiver. The usage of mode one is compatible with our HC-SR04 module Features: 1. Small size and easy to use: 2. Low voltage and low power consumption: 3. High measurement accuracy; 4.

TTL pulse above 10uS; 2. Serial port sending command 0X55 Output echo signal Output pulse width level signal, or TTL Wiring: 3-5. 5V (power +) Trig (Control) RX Echo (output) TX GND (power-) Working temperature: -20-+70 degree Function description: 6 modes Mode 2: M2 short connection is serial port controlled output Mode 1: M1 short connection is automatic serial output Mode 0: Mode floating = trigger pulse width output (factory default mode) Mode 3: Mode welding 200K = automatic distance pulse width output Mode 4: Mode welding 360K = low power pulse width mode output Mode 5: Mode welding 470K = switch mode output Mode 1: Mode=open means no welding. The mode is explained as follows Basic working principle: (1) Adopt IO port TRIG to trigger ranging. Present a high level signal of at least 10us. (2) The module automatically sends eight 40khz square waves and automatically detects whether a signal returns; (3) When a signal returns, a high level is output through the IO port ECH0. The duration of the high level is the time from the transmission of the ultrasonic wave to the return. Test distance height = (high level time * speed of sound (348M/S))/2. (4) After the module is triggered for ranging, if the echo cannot be received (the reason exceeds the measured range or the probe does not face the measured object), the ECHO port will automatically become low after 40MS, marking this time The measurement ends, regardless of success. Mode 2: Mode=47K (or directly short M1 bit) UART automatic output The UART automatic output mode outputs the measured distance value (hexadecimal number) according to the UART communication format. This mode does not require an external trigger signal. The module can automatically measure every 100ms. The TX pin outputs the measured distance value after each measurement is completed. Mode 3: Mode=120K (or short M2 bit directly) UART controlled output The UART controlled output method outputs the measured distance value (hexadecimal number) according to the UART communication format. In this method, the trigger command oX55 signal needs to be added to the RX pin. The module measures once every time the command is received. The foot outputs the measured distance value. The command trigger cycle should be greater than 60ms. Mode 4: Mode=200K high level (PWM) pulse width automatic output Under the pulse width PWM automatic output, the module automatically measures at a period of 200ms, and outputs a pulse width high level corresponding to the distance after the measurement. Calculating distance mode reference mode 1. Mode 5: Mode=360K low power consumption (PWM) high level pulse width controlled output In low-power mode, the module's shut-down dog is disabled. This module is suitable for battery-powered users. The static power consumption is less than 70UA. The working distance measurement method is the same as mode 1. Mode 6: Mode=470K switch output The module will set a threshold value at the factory, the default is 1.5 meters. The module performs ranging every 200ms. When the detected distance value of the target is less than the set threshold, the Echo pin outputs a high level. The currently detected distance value is greater than the set threshold, and the Echo pin outputs a low power. In order to improve the stability, the factory defaults that the distance detected by the target for two consecutive times is less than the set threshold. Signal, no driving ability. Transistor drive relays should be added during application. If there are special requirements, you need to modify the threshold or other settings, you need to specify when purchasing.
