pzsmocnCollision Sensor/Micro Snap Switch/Limit Module Compatible with Raspberry Pi and Arduino Board. for Smart Homes, Offices, 3D Printer and Teaching Interact with Robots.

I like this little microswitch as it came well packaged, it works well, and it makes install pretty easy with the included cable and pcb module design. It's really simple to wire up as you can see the diagram from the photos and it is pretty simple when it comes down to function.PZSMOCN/CQRobot (if you visit the pzsmocn wiki you'll get redirected to cqrobot now so must have bought them) makes high quality components so I haven't had an issue with them previously nor did I expect one here. The cable was good quality and I like how they went for the 3 pin JST input to make connecting easier. The switched worked flawlessly returning a low signal on activation and high signal normally. The sensor includes an LED which helps indicate it was activated which is nice as I like being able to see visually things are working like that.This product is listed on the CQRobot wiki as a "Crash Sensor" if looking up details. The wiki includes some basic demo code for Arduino and the Raspberry Pi.

This switch is constructed well. Good size mounting holes. The switch on the board is the same as type as found on a 3D printer end stop.Out of curiosity, I connected this to my test printer controller board running Marlin 2x. It is not pin compatible with a standard end stop. I didn't try changing the configuration, but it may work by inverting the end stop in the Marlin configuration. Note the footprint on this switch is larger than most 3D printer end stop boards.I connected this to an Arduino Uno. The black wire to ground, the red wire to 5V and the green wire to a digital pin (I used D3 as shown in the product image). I wrote a basic program to test the switch (see code below).In my testing, I found that this switch does NOT handle debouncing.#define PIN 3int _previousValue = HIGH;void setup(){ Serial.begin(115200); pinMode(PIN, INPUT); _previousValue = digitalRead(PIN); Serial.println("Ready.");}void loop(){ int value = digitalRead(PIN); if (value == HIGH && _previousValue == LOW) { Serial.println("Button released."); _previousValue = HIGH; } else if (value == LOW && _previousValue == HIGH) { Serial.println("Button pushed."); _previousValue = LOW; } // // Comment the following line to see the switch bounce. // delay(50);}I found that 50 milliseconds will debounce the switch.I like the connector. Makes it easy to use and connect into a circuit.Overall a good switch module.

Came well packed and the build quality looks good.Connections to board are self-explanatory.Little to no information supplied with product, just a couple of references to webpages on packet label.The module is basically a micro switch mounted on PCB and whilst it works as expected and I am sure there are occasions when having a micro switch fitted to a PCB board would be an advantage,But I would think the far simpler cost effective solution would be to fit the switch directly in place.In my opinion far too big and expensive for what it does, (£6.99 at time of review) when compared to the more cost effective solution of directly fitting a cheap simple switch that preforms the same functionality.

Das Produkt kommt schnell und gut verpackt hier an. Der Kollisisons-Sensor ist für viele unterschiedliche Möglichkeiten einsetzbar so z.B. für Roboter und Automation. Die Qualität des Bauteiles ist einwandfrei da gibt es nichts zu meckern.Der Sensor schaltet bei Endstops z.B. für 3 D-Drucker, oder allgemein bei Stop/Anschagfunktionen.Da der Preis für dieses eine Modul wie ich finde zu hoch agesetzt war erfolgt hier ein Stern Abzug.

The media could not be loaded.  Este sensor es como el que se utilizan en impresoras 3D, CNC o cualquier montaje de electrónica de este estilo, normalmente para controlar el tope hasta donde el motor debe estar activo, conocido como final de carrera.En este caso este final de carrera de la marca Pzsmocn, es muy sencillo de usar. Viene protegido en una caja de plástico e incluye un cable de conexión de 210 mm de largo con un pequeño recoge cable de velcro de color amarillo. Los cables acaban en un cable con conector Dupont de tipo hembra, por tanto para conectarlo a un Arduino hará falta uno macho a macho, en el caso de Raspberry se podrá conectar directamente.El sensor es muy sencillo de usar, en arduino se conecta al pin 3 el cable verde, el rojo de voltaje al pin de 5V del Arduino y el negro de tierra el GND del Arduino.Como código de ejemplo la marca Pzscmocn tiene una web con un wiki, con los esquemas de conexionados y ejemplos de código tanto par Arduino como para Raspberry, la dirección de la web se puede encontrar en la misma ficha de este producto o bien está impresa en el propio sensor.El sensor funciona perfectamente, devuelve un estado de HIGH o LOW dependiendo de si está presionado o no, actuando a modo de interruptor. Y mientras se mantiene presionando constantemente se mantiene el estado.La calidad del sensor es excelente, muy buena calidad de construcción e incorpora en la propia placa 4 agujeros por si queremos fijarlo con tornillos a nuestro montaje.

Ho deciso di ordinare questo finecorsa per arduino in quanto sto realizzando un progetto in cui è necessario.il prodotto arriva ina piccola scatolina di plastica con il logo del produttore e all'interno troviamo l'articolo ben sigillato in una bustina.La qualità è ottima e anche le saldature sono ben fatte.L'utilizzo di pulsanti con arduino è veramente basilare, tuttavia questo prodotto offre una scheda con fori di montaggio e led di feedback , inoltre è dotato anche di connettore.Tutto ciò lo rende più professionale e più piacevole esteticamente, rendendo i vostri progetti davvero ben fatti.il mio voto è di 4 stelle per il prezzo, che nonostante tutte le caratteristiche è davvero troppo elevato.Rimane comunque un acquisto consigliato.

Se trata de un interruptor para conectar a Raspberry o Arduino (u otros microcontroladores). En este caso, lo considero mas un interruptor que un sensor de colision. Porque? Muy sencillo, es una plaquita con un interruptor, de tal manera que se indica que hay colision cuando el interruptor es pulsado... Si, tal cual, tiene un interruptor que se pulsa, sin mas...Me esperaba literalmente un sensor, de tipo proximidad o algo similar, pero no es asi. A mi no me sirve mucho porque con el tamaño que tiene, no me parece practico. Se podria hacer lo mismo en menos espacio, con un interruptor, asi que estoy un poquillo decepcionado.Pros:-Bien construido, se ve bien de calidadContras:-Algo voluminoso-Es un interruptor, no hay sensor de nada.
