SR04T Waterproof Ultrasonic Sensor Jsn-sr04t Distance

AJ-SR04M Waterproof Ultrasonic Distance Sensor?Waterproof Ultrasonic Distance Sensor gives distance value using ultrasonic waves. AJ-SR04M Ultrasonic Sensor can be read using any microcontroller board like ARDUINO UNO, ARDUINO DUE, ARDUINO PRO MINI, ARDUINO NANO, AND OTHER DEVELOPMENT PLATFORMS.

Electrical parameters:

• AJ-SR04M Operating voltage: DC 5VQuiescent current: 5mATotal current work: 30mAAcoustic emission frequency: 40khzFarthest distance: 4.5mBlind: 25cmWiring: + 5V (positive power supply)Trig (control side) RXEcho (the receiver) TXGND (negative)Module size: 41mm * 28.5mmResolution: about 0.5cmAngle: less than 50 degreesWorking temperature: -10 ~ 70 ?Storage temperature: -20 ~ 80 ?

Product Features:

• small size, easy to use;
• low voltage, low power consumption;
• high accuracy;
• strong anti-jamming;
• integrated with wire enclosed waterproof probe, suitable for wet, harsh measurement occasions.

Application:

• Horizontal distance;
• obstacle avoidance, automatic control;
• the object approaches, there is a perceived
• traffic control;
• security, industrial control;
• artificial intelligence, and research

The basic working principle:

• (1) using IO port TRIG trigger location, to the high-level signal of at least 10us;
• the module automatically sends 8 40KHz Fang Bo, automatic detecting whether a signal return;
• a signal return, a high level is output through the IO port ECHO, the time duration of the high level is
• ultrasonic from launch to return. The test distance = (high level time * speed of sound (340M/S)) /2;
• This module uses the simple method, a control port with a 10US above high level, can wait for a high level
• output at the receiving port. An output can drive the timer when this port is low can read the timer value,
• this time for the location of the time can be calculated distance. So constantly cycle test, that can achieve
• the measurement of the value of your mobile.Package included?1 x Ultrasonic Module Distance Measuring Transducer Sensor Perfect Waterproof
