Ultrasonic Flow Meter - Project Guidance - Arduino Forum
WEBMar 17, 2017 — Ultrasonic Flow Meter. Using ArduinoProject Guidance. Xhale March 17, 2017, 2:30am 1. Hi! I was working on a flow meter with Arduino that used a turbine, but I was thinking that it would be cool to use an ultrasonic sensor instead. My current plan is to use something like the Arduino Uno and two SR04 ultrasonic sensors.
HC-SR04: tests on accuracy, precision and resolution of ultrasonic ...
WEBMay 27, 2014 — Hi to all! I have been using the ultrasonic sensor HC-SR04 for a while. I was puzzled to read in most pages that people were happy with them because my experience was mixed. Now I am planning to use them for a project where I need to know more about their specifications, so I have run some domestic tests on their accuracy, precision, resolution, and angular and linear ranges. I have uploaded a ...
Ultrasonic sensor hc-sr04 tracking and following object
WEBAug 30, 2024 — Ultrasonic sensor hc-sr04 tracking and following object. Hi everyone, I’m currently working on a school project involving a servo motor and an ultrasonic sensor. The goal of the project is to have the sensor track an object as it moves around. However, I'm facing an issue where the sensor isn't following the object correctly in all directions.
Ultrasonic Sensor Inconsistent Reading - Arduino Forum
WEBDec 9, 2013 — Hi All, I'm working with a project that uses 4 pin hypersonic sensors and I'm getting inconsistent distances even when I'm not moving. Here's what code I'm using and what the sensor is outputting: Code digitalWrite(trigPin, LOW); delayMicroseconds(2); digitalWrite(trigPin, HIGH); delayMicroseconds(10); digitalWrite(trigPin, LOW); delayMicroseconds(15); duration = pulseIn(echoPin, HIGH ...
Using an Ultrasonic Sensor to start a timer - Arduino Forum
WEBJan 27, 2022 — Using Arduino Programming Questions. solis22 January 27, 2022, 1:36am 1. Hey, so my Capstone group is working on our prototype and we're stuck on how to get the ultrasonic sensor to start a timer. We believe it's a coding issue so if anyone can help us troubleshoot our code it would be much appreciated. #include <LiquidCrystal.h>.
Ultrasonic Sensor using Uart Serial Communication? - Arduino …
WEBMar 14, 2019 — Hi everyone! I have some decent experience tinkering with Arduino using simple digital and analog pins, but I've never dealt with a sensor that uses a communication protocol like UART serial communication. I've followed some of the examples around the forums, but it seems as if the SoftwareSerial library is mostly for sensors that have both RX and TX lines. My sensor is odd in the sense that ...
Using Ultrasonic Sensor and ESP8266 in Arduino IOT cloud
WEBApr 28, 2023 — The following function allows you to obtain more information. related to the state of network and IoT Cloud connection and errors. the higher number the more granular information you’ll get. The default is 0 (only errors). Maximum is 4. */. setDebugMessageLevel(2); ArduinoCloud.printDebugInfo(); ArduinoCloud.update();
Ultrasonic sensor + Sleep mode - Sensors - Arduino Forum
WEBApr 30, 2019 — Paul. That sensor won't do any measurement without the Arduino telling it to do so. It definitely won't be able to wake up the Arduino as won't pick up activity without the Arduino running. But depending on your scenario you might put the Arduino to sleep for a few seconds, wake up, make a measurement and go to sleep for a few seconds again. If ...
ultrasonic wind sensor - Exhibition - Arduino Forum
WEBAug 29, 2010 — A common misconception about using a sonic anemometer is that you can measure the wind speed by measuring the Doppler frequency shift of the ultrasonic signal. Recall the high school physics experiment relating to train whistles changing pitch as they approach and recede from a stationary listener.
Ultrasonic sensor not giving correct readings - Arduino Forum
WEBDec 10, 2018 — That is the first place to begin. Also look at some of your computations that use floating point to compute an integer. Paul. Hi, You should try this code out, it worked for me: Connect Pins as follows: Pin # 11 of Arduino is connected with Echo Pin of Ultrasonic Sensor HC-SR04. Pin # 12 of Arduino is connected with Trig Pin of Ultrasonic Sensor.
