25/01/2020· The PIR sensor itself has two slots in it, each slot is made of a special material that is sensitive to IR. The lens used here is not really doing much and so we see that the two slots can 'see' out past some distance (basically the sensitivity of the sensor). When the sensor is idle, both slots detect the same amount of IR, the ambient amount radiated from the room or walls or outdoors. When a warm …

19/04/2018· The following image shows a standard PIR sensor test set up. The output and Vss pins (negative pin) of the PIR is connected with an external pull down resistor, the Vdd pin is supplied with a 5V supply. A stationery black body generates the required equivalent infrared radiation for the PIR sensor through a chopper mechanism.
31/05/2020· The PIR sensor consist of 3 pins, Pin1 corresponds to the drain terminal of the device, which connected to the positive supply 5V DC.

30/04/2020· /5 (404 Views. 12 Votes) For a current, the PIR Sensor works from to 5v DC and gives a TTL output which is directly given to a micro-controller or to relay through a transistor. The PIR sensor consists of a pyroelectric sensor and a Fresnel lens. This curved lens concentrates infrared radiation toward a detector's sensor.
PIR sensor is made of ceramic material that generates surface charge when exposed to infrared radiations. As the amount of radiation increases, the surface charge generated increases. A FET is used to buffer this signal. As the sensor is sensitive to a wide range of radiations, a filter is used which limits the infrared rays falling on the sensor to 8um-14um range. Thus the output of an IR sensor is a …
