Suggestion PIR Sensor

#1 · May 26, 2026, 8:52 am

Bonjour,

Je suis un utilisateur régulier de SimulIDE et j’apprécie énormément votre travail. Je soutiens le projet via des dons lorsque je le peux, car c’est un outil précieux pour mes projets électroniques et Arduino.

Je me permets de vous contacter pour vous proposer l’ajout d’un composant très utile : un capteur PIR (détecteur de mouvement) simple, avec trois broches (VCC, GND, OUT) et une impulsion configurable.

Ce composant est très courant dans les projets Arduino, ESP32 et microcontrôleurs, et son intégration native dans SimulIDE serait vraiment pratique pour de nombreux utilisateurs.

Un comportement simple suffirait :

double‑clic ou événement interne pour simuler une détection
sortie OUT passant à 1 pendant un délai configurable
retour automatique à 0

Si cela est envisageable dans une prochaine version, ce serait une excellente amélioration pour la bibliothèque de capteurs.

Merci encore pour votre travail remarquable et pour le temps que vous consacrez au développement de SimulIDE.

Cordialement, Patrick

Hi and welcome to the forum.

Please can you use English here?

Bonjour Patrick,

it seems you simply need a monostable multivibrator. E.g. 555, 74123.
Or you can create your own component: https://simulide.com/p/scripted/

Hi arcachofo, Thank you for your message and for the warm welcome.

Sorry for writing in French earlier — I will continue in English from now on so that everyone on the forum can follow the discussion.

I really appreciate your work on SimulIDE. It is a great tool for learning, experimenting and quickly testing ideas with microcontrollers. My suggestion about adding a simple PIR sensor component comes from the fact that this device is very commonly used in Arduino and ESP projects, and having a native component would make simulations easier for many users.

Of course, I understand that development priorities are complex, and I am not demanding anything. It is simply a feature suggestion that could be useful for the community.

Thank you again for your time and for maintaining SimulIDE.

Best regards, Patrick

Hi nemka, Thanks for your reply. Yes, using a monostable like a 555 or 74123 is a possible workaround. My suggestion was mainly about having a simple built‑in PIR component for convenience, but I appreciate your input.

I have this component that generates a pulse of configurable length.

It is very simple but maybe it is useful.

Using a background image, changing icon and changing the name it could be converted into a simple PIR sensor.

Hi @patrick74, thanks to you for understanding.

About the PIR sensor, you will notice that there are no sensors in Simulide that only do voltage changes and things like that because that kind of input is easy to simulate with existing components.
And if someone wants to do this kind of components it's easy with Subcircuits or Scripts.
