PARALLAX PIR SENSOR Datasheet

The PARALLAX PIR SENSOR Datasheet is your comprehensive guide to understanding and implementing the popular Parallax Passive Infrared (PIR) sensor. This document details the sensor’s specifications, operating characteristics, and application circuits, enabling hobbyists, students, and professionals to effectively integrate motion detection capabilities into their projects.

Unveiling the Secrets of the PARALLAX PIR SENSOR Datasheet

The PARALLAX PIR SENSOR Datasheet serves as a crucial resource for anyone working with this type of sensor. It meticulously outlines the sensor’s technical specifications, covering parameters like supply voltage, current consumption, detection range, and field of view. Understanding these specifications is fundamental to ensuring proper sensor operation and achieving optimal performance in your application. The datasheet also presents typical application circuits and wiring diagrams, simplifying the integration process.

Specifically, the PARALLAX PIR SENSOR Datasheet will help you understand:

• The sensor’s operating voltage range (typically 3.3V to 5V)
• The sensor’s current draw (usually in the microampere range)
• The detection range, which varies but can be up to several meters
• The output signal characteristics (digital high/low indicating motion)

Understanding these elements allows for correct project integration. Without this information, it is possible for the sensor to not work correctly.

Beyond basic specifications, the PARALLAX PIR SENSOR Datasheet often includes information about the sensor’s internal workings and factors that can influence its performance. This might involve details about the Fresnel lens used to focus infrared radiation onto the sensor element, or explanations of how ambient temperature and humidity can affect detection accuracy.
