uxcell a15113000ux0594 Max 25V Voltage Detector Range 3 Terminal Sensor Module for Arduino

in this tutorial I'm going to teach you how to read out a voltage sensor for this tutorial you need an Arduino a voltage sensor a jumper wire male-to-female and I'm using three combined together but you can also use three separate ones and optionally a power plug with two male-to-male jumper wires I'm going to use this as the power source which were measuring with the voltage sensor you're looking at a skin medics of a voltage sensor and as you can see it's pretty straightforward we have the V in which is a lot between 0 and 25 volt as shown or your censorship your voltage shield two resistors r1 and r2 and we have here a split of the circuit which is going to V out and the other one is going to r2 the nice thing about a circuit is that it can divide the voltage of the input to a certain output that's why this is called a voltage divider there is a trick with these two resistors they ha
