Hengjiaan Ultrasonic Module Distance Measuring Transducer Sensor
Operating voltage: DC 5V Quiescent current: 5mA Total current work: 30mA Acoustic emission frequency: 40khz Farthest distance: 4.5m Blind: 25cm Wiring: + 5V (positive power supply) Trig (control side) RX Echo (the receiver) TX GND (negative) Module size: 41mm * 28.5mm Resolution: about 0.5cm Angle: less than 50 degrees Working temperature: -10 ~ 70 ¡æ Storage temperature: -20 ~ 80 ¡æ Product Features: 1£¬ small size£¬ easy to use; 2£¬ low voltage£¬ low power consumption; 3£¬ high accuracy; 4£¬ strong anti-jamming; 5£¬ integrated with wire enclosed waterproof probe£¬ suitable for wet£¬ harsh measurement occasions. Application: 1£¬ Horizontal distance; 2£¬ obstacle avoidance£¬ automatic control; 3£¬ the object approaches£¬ there is a perceived 4£¬ traffic control; 5£¬ security£¬ industrial control; 6£¬ artificial intelligence£¬ and research The basic working principle: (1) using IO port TRIG trigger location£¬ to the high level signal of at least 10us; (2) module automatically sends 8 40KHz Fang Bo£¬ automatic detecting whether a signal return; (3) 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 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.
