Davitu Electrical Equipments Supplies - JSN-SR04T DC 5V Waterproof Ultrasonic Module Distance Measuring Transducer Sensor Connector

1, the stability of the module performance, measure the distance accurately. Energy and foreign SRF05, SRF02 ultrasonic ranging module and other comparable. Module precision, blind spots (25cm), stable ranging is a strong basis for this successful product to market.   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.   product should be used:  A 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 operating principle:  (A) use IO port TRIG trigger ranging, high-level signal to at least 10us.  (2) the module automatically sends eight 40khz square wave, and automatically detects whether a signal return.  (3) a signal is returned, through the IO port ECHO outputs a high level, high duration is Ultrasonic time from launch to return. Test distance = (high time * speed of sound (340M / S)) / 2.  This module is simple to use, a control port more than send a 10US high, you can wait to receive high output port. One has the timer output can be opened, the mouth goes low when this can be read timer value, this time for the distance of time, before the calculated distance so constant cycle test, which can reach values as you move the measurement
