Gikfun HC-SR501 Human Infrared Pyroelectric Sensor Module and 5V 1 Channel Relay Module EK8202

hi welcome to another unit tutorial from Robo Jack's in this video we are going to see how we can use this HC sr5 for one motion sensor with a relate to control an AC ball alarm or another load using Arduino now there is no motion if I bring my hand it just detects it and turns on the light you can get the code for this project by clicking on the link of the description below which will take you to Robo Jack's that come / learn / Arduino let's get started with this you three pence hairs this goes to five volts from the left side where there is a diode this goes to five volts you can connect it up to 20 volts doesn't matter because we have a voltage regulator and generally it will regulate it but in our just connected to five volts this is connected to the pen four of our Arduino and this is a ground is here grounded here the middle one is a signal potentiometer this is for the sensitivi
