5PCS KY-003 Hall Effect Magnetic Sensor Module for Arduino PIC AVR Smart Car TW Durable Magnetic Sensor

hello and welcome to my channel in this video I'm going to show you how this hot sensor module works and how you can use them for your projects if you are interested in the sensor or in the kit where it's coming from I will let you a link in the description below so let's get started hi sensors are very popular those days they can be used in many applications for example you can use them in a DC motor in order to sense the position and with a little bit of mathematics you can also calculate the speed and the acceleration of the motor they are also used as magnetic switches or proximity sensors so now let's have a look how this is working a hot sensor is actually nothing else than the thin conductive plate through which one flows the current they are also a little bit of electronics behind this but we are not going deep in detail in this video so let's imagine we have a thin conductive p
