Using the HC-SR04 Ultrasonic Distance Sensor with Arduino The HC-SR04 Ultrasonic Distance Sensor is a staple in robotics projects. This inexpensive device is capable of measuring the distance between itself and the nearest solid object from 2 to 400 centimeters. Exactly what you need to keep your...
Arduino Current Sensor This Arduino based current, voltage, and power sensor/meter tutorial was created for hacktronics by Steve Spence. For my off-grid Ham Radio and Solar projects, I needed a way to measure volts, amps, watts, amp hours and watt hours. There's a couple of commercial pr...
HallEffectSensor-Arduino 一个用Arduino编写的简单程序,我用来轮询连接到Arduino板的霍尔效应传感器。 霍尔效应传感器的值被发送到串行端口。 这是我在整个博士学位期间开发的一套程序之一。 您可以在这里阅读有关我的研究的更多信息: : 以下是我如何将霍尔效应传感器
The hall effect sensor can detect magnetic field changes in its surroundings The measurements from the sensor can increase or become negative depending on the magnet pole facing the sensor. We hope you’ve found this tutorial useful. For more projects with the ESP32 you can check our project’...
Enhance your Arduino projects with the Water Flow Sensor YF-S201, a high-accuracy paddle type flow meter with a stainless steel impeller for durability and a broad 1-30L/min flow range.
霍尔传感器(Hall Effect Sensor)是根据霍尔效应制作的一种磁场传感器,当恒定电流通过内部的霍尔半导体片时,将在垂直方向产生电位差即霍尔电压。这个霍尔电压随磁场强度的变化而变化,磁场越强,电压越高,磁场越弱,电压越低。虽然霍尔电压很小,通常只有几个毫伏,放大后就足以输出较强信号。图1. 霍尔传感器原理霍尔传感器...
