PIR Motion Sensor Light Detected Resistor And Motion Controller Projects

procedure for detecting motion for sles explain, the working principle the module actually consists of pyroelectric sensor which generate energy when exposed to it that means when human or animal body will get in the range of the sensor to detect the movement because the human body anymore Badi he meets heat energy in a form of infrared radiation that’s why the name of the Saints are comes from a passive Infrared sensor

and the term as if he is that the sensor is not using any energy for the taking purposes it just walked by the taking the energy given off by the other objects the module also consist especially designed cover nayme defensive plays which focuses the infrared signals on to the power electric sensor ok now let’s connect the module 2 arduino board the module has three piece ground and VCC for powering the module in an output pain which gives Hai logic level if an object is the Tech that also its a stupid this your mother’s one for adjusting the sensitivity of the sensor and the other for adjusting the time the

output signal space hai when the object is the Tech this time can be adjusted from 0.3 seconds up to 5 minutes the module has 3 war base with jumper between two of them this page or for selecting the trigger Mod the first one is called non repeatable Trigger and works like this when the sensor output the sky and the delay time is over the output will automatically change from high to low level airport code repeatable Trigger will keep the output high all the time until the detective object is press Zone in the sensors range as an example for this tutorial I will make a circuit that will turn on a high voltage line when the sensible the Tech an object here is the Circus temerity output 3 of the sensor will be connected to the pin number 8

on the arduino board and when an object will be detected the PIN number 7th will activate the relay module in the high voltage climb will turn on for more details call the relay module works you can check my arduino relay tutorial here arduino code for this example it’s quite simple we just need to define the p i r sensor being as input and they’re really penis output using the digital read function we will read the output of the sensor and if it’s high or if an object is detected it will activate the really for activating the relay module will send the logical thoroughly input been works inversely

here demonstration of the example know that after powering the sensor module it needs about 20 to 60 seconds to warm up in order to function properly now when I will put my hands in front of the sensor the riverview activate the lamp but not that even if I move my and constantly the lamp will turn off after the adjusted the lead time is over because the pierces is in non repeatable Trigger Mod if I change the sensor with the jumper to the repeatable trigger mod and I constantly move the hen the when will be constantly on as well I need to turn off after the movement is gone and set the late time is over
