Infrared sensors - Sensor Technology - Metropolia Confluence

The threshold value of the PIR sensor is kept low to capture weak motions if the signal value is between the two threshold values that mean there is no motion and the reading is 0 V. If signal value is higher than the threshold value then the sensor has detected a motion, and the indicator is activated to identify the detection of motion.[2],[7

Senzori PIR -

Jan 04, 2014· Pentru senzorul PIR DSC conectarea se face putin diferit. Datorita faptului că acest senzor se alimentează la 12V, pinul de semnal v-a face trecerea de la 12V la 0V în momentul in care se detectează mişcarea. Dacă punem cei 12V pe una dintre intrările Arduino riscăm să îl „prăjim”, lucru pe care nu ni-l dorim.
