Ultrasonic module HC-SR04 the module performance is stable, accurate measurement of distance. Can foreign SRF05, SRF02 ultrasonic ranging module is comparable to. Module with high precision, the blind (2cm) super close, stable range is effective according to the product to the market successfully! Main technical parameters The use of voltage: DC5V High level output: 5V Static current: less than 2mA Output: Base on 0V Induction angle: not more than 15 degrees Detection range: 2cm-450cm High precision: up to 0.3cm PCB board size: 4.5*2.0CM Connection mode, VCC, trig (control side), echo (receiver), GND Using the method of the product: 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 the mouth becomes low level can read the timer value, then the ranging time, can calculate the distance so continuous cycle detection, you can reach your mobile measurement values. working principle of module: The IO trigger range, high level signal to at least 10us; Module automatically sends 8 40KHz Fang Bo, automatic detecting whether a signal return; A return signal, outputs a high level through IO, duration of high level is ultrasonic from launch to return time. Test distance = (high level time * speed of sound (340M/S)) /2; Package Included: 5PCS x Ultrasonic module HC-SR04 Payment: We only accept paypal.Thank you for your support!
