1 piece 5V ultrasonic sensor waterproof module JSN-SR04T ultrasonic distance measuring module with waterproof sensor

Specifications: Working voltage: DC5V Resting working current: 5mA Total working current: 30mA Wave transmission frequency: 40 kHz Max. measuring distance: 5m Blind zone: 25cm Size: 28.5 41mm Resolution: about 0.5cm Angle: <50 degrees Working temperature: -10℃~70℃ Storage temperature: -20℃~80 Wiring: +5V (power supply positive) Trigg (control) RX Echo (reception) TX GND (power supply negative) Formula: US / 58 = cm or US / 148 = inches; Or: distance = high level time speed of sound (340 m / s) / 2; The recommended test cycle is more than 60ms to prevent the echo signal from being transmitted. Package includes: 1 x distance measuring module and sensor

Product Features

• Working principleThe IO port TRIG trigger measuring distance generates a high level signal for at least 10 S spent. The module automatically sends eight 40 kHz square wave signals and automatically detects whether a jerk signal is present. When there is a return signal, through the E/O port of the high level ECHO output, the duration of the high level is the time of the ultrasonic wave from sending to returning.
• Instructions for useThe ultrasonic timing chart shows that you only need to provide a pulse trigger signal of more than 10S. The module inside sends eight 40 kHz cycles and detects the return wave. Output an echo signal as soon as the jerk signal is detected. The pulse width of the echo signal is proportional to the measured distance. Therefore, calculate the distance with the distance between the transmitted signal and the received echo signal.
• Stable performanceThis distance sensor Small size, convenient to use, it can measure distance accurately, low voltage, low power consumption, stable performance
• ApplicationThis ultrasonic sensor high measurement accuracy, strong anti-interference ability, integrated with a wire-encapsulated waterproof sensor, suitable for wet, rough measurement applications
• ApplyWidely used for horizontal distance measurement, obstacle avoidance, automatic control, security, industrial control, etc.< /li>
