Frequently Asked Questions

What is the operating voltage for the PT8A2648WEX PIR sensor?

The PT8A2648WEX operates from a single 5V DC supply. It is designed to be compatible with standard digital logic levels and can be powered directly from a regulated 5V source, such as those commonly found in microcontroller development boards (Arduino, Raspberry Pi) or dedicated power supplies.

What type of output signal does this PIR sensor provide?

This integrated IC provides a processed digital output signal. It internally conditions the raw pyroelectric sensor signal, filtering out noise and providing a clean logic-level output that indicates motion detection, which can be directly read by a microcontroller GPIO pin.

What is the typical detection range and field of view for this sensor?

As an integrated IC, the PT8A2648WEX requires an external Fresnel lens or reflector to define the detection range and field of view. The sensor element itself is highly sensitive, and the effective range (typically 5-10 meters) and coverage pattern are determined by the optical design of the lens assembly used in front of the module.

Can this sensor be used outdoors?

The specified operating temperature range is -20°C to 70°C, which covers many outdoor conditions. However, for reliable outdoor use, the entire assembly must be housed in a weatherproof (IP65 or higher) enclosure that protects the electronics from moisture and dust while allowing the IR radiation to pass through a suitable window material.
