Our Story Parallax

Parallax knew the BASIC Stamp microcontroller would be special – it was the tool they needed to do their own hobby projects. The fact that the BASIC Stamp module would create its own industry was probably unknown by Parallax founders, but it quickly became apparent that the small computer had its own group of enthusiasts.

55528027: Parallax : PIR Sensor (Rev B) : Electromechanical

PIR Sensor (Rev B) The PIR (Passive InfraRed) Sensor is a pyroelectric device that detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected the PIR Sensor outputs a high signal on its output pin. This logic signal can be read by a microcontroller or used to drive an external load.


PIR Mini Sensor Parallax

The PIR Mini Sensor’s compact form factor is ideal for smallscale projects, and those where the electronics need to be hidden or protected. The narrow, vertically oriented board can slip through a hole in an enclosure to hide and protect the electronics, leaving only the small lens visible on the outside.

PIR Sensor (55528027)

PIR Sensor (55528027) The PIR (Passive InfraRed) Sensor is a pyroelectric device that detects motion by sensing changes in the infrared (radiant heat) levels emitted by surrounding objects. This motion can be detected by checking for a sudden change in the surrounding IR pattern. When motion is detected the PIR sensor outputs a


WideAngle PIR Sensor Parallax Inc | DigiKey

Mar 05, 2014· Similar in functionality to Parallax''s PIR sensor (55528027), the wideangle PIR sensor features a larger detection angle of 180°. This makes it ideal in applications where users need to track movements across a large, open area. The wideangle PIR sensor is a pyroelectric device and it detects motion by sensing changes in the infrared levels emitted by surrounding objects.


PIR Sensor trigger — Parallax Forums

Aug 17, 2012· If the false triggering is constant rather than periodic and random you might want to add a weak (say about 20K) pulldown between the output and ground. The output of the sensor is really intended for the typical impedance of a microcontroller input, not a scope. Also place a good size filtering cap across the power supply rails of the PIR.


PIR Motion Sensor with Piezo Buzzer and LEDs — Parallax Forums

Apr 30, 2020· I am trying to program a PIR motion sensor that will sense motion and turn on a piezo buzzer and LED light that are all connected on a Parallax Propeller. The …


Parallax PIR Sensor | PlanetArduino

Connecting a PIR sensor to an Arduino board can be done easily. PIR sensors consist of 3 pins, Vcc (Positive Voltage), Vss (Ground), and Signal. Interfacing it to the Arduino only requires +5v, GND and a digital input pin. I put a short video clip on YouTube showing how the sensor …
