Control Servo Using PIR Sensor : 5 Steps (with Pictures ...

The scenario is, when the PIR SENSOR detects motion, the door opens BUT it closes after 5 seconds(5 seconds was based on the adjustment I've done on the Time Delay trimmer of the PIR). Now, the condition is, when the PIR detects someone and he/she is staying at the opening of the door, the door should remain open. Can you please help me figure out the logic behind that automated door? where …

Causes of false motion detection alerts or PIR triggering ...

In this case motion is detected by means of the PIR sensor, a passive infrared sensor. This sensor detects emitted infrared energy from objects (humans and animals, but also cars) in the form of heat. In general differences of around 5-10º Celsius compared with the ambient temperature in the field of view and within a 10m /30ft range of the camera are detected. However, other factors can also ...
