Storage temperature: -20~80°C
Applications:
1. Horizontal ranging;
2. Obstacle avoidance and automatic control;
3. the object is close, there is awareness
4. Traffic control;
5. Security and industrial control;
6, artificial intelligence, teaching and research
Basic working principle:
1. Use IO port TRIG to trigger ranging, giving a high level signal of at least 10us;
2. The module automatically sends 8 square waves of 40khz to automatically detect whether there is a signal return;
3. There is a signal return, and a high level is output through the IO port ECHO, and the high level duration is the time from the transmission to the return of the ultrasonic wave. Test distance = (high time * sound speed (340M / S)) / 2;
This module is easy to use. A control port sends a high level above 10US, so you can wait for the high level output at the receiving port. You can turn on the timer when there is an output. When this port goes low, you can read it. The value of the timer, at this time is the time of the distance measurement, in order to calculate the distance. Such continuous cycle measurement, that is, you can reach the value of your mobile measurement.
