Multiple sr04 with a single pin
WebAnalog output processing lets a fixed HC-SR04 sensor detect multiple objects. HC-SR04 ultrasonic sensors are useful in a wide variety of automation tasks, for determining the distance to an object. If you need to deal with multiple objects, this normally means buying or building a scanning setup, or perhaps mounting a few fixed sensors at ... Web23 mar. 2024 · However, after a time-out and with the distance between the object and the sensor in range, the Echo pin fails to be set low after a trigger pulse is generated. The only way to fix this condition is to power down the sensor and power it back up again. (I have verified the state of the Echo pin by using an oscilloscope.) hc-sr04. Share.

Web1 feb. 2016 · The HC-SR04 has a 4 pin interface: vcc, gnd, trigger, and echo. The trigger pin sends a 10us pulse triggering the sensor to send its 40khz ultrasonic pulse. The echo pin receives a digital pulse from the sensor proportional to the distance detected by the sensor. I have successfully interfaced the HC-SR04 sensor with an Arduino using 3 pins … Web14 mar. 2024 · 1 Answer. Check the pin color of your HC-SR04. Models with "brass" colored pins have a defect. They might and will return false readings. Models with "silver-y-ish" pins are more precise. The defect isn't there. Also, try using pins 2 & 3 for the distance sensor and something else for the PWM.
