knock sensor – это датчик вибрации, реагирует на вибрацию.
Для чего он нужен? ну честно не могу сказать. В принципе можно его приделать на окно, и если будут пробовать разбить окно, можно настроить так, чтоб Вас ардуино оповестило об этом. Я же его заказывал, чисто поиграться, мне интересны все датчики которые бывают на ардуино.
Схема подключения данного датчика простая, у него имеется три пина следовательно +, – датчика мы подключаем к ардуино +,- а третий пин датчика вибрации мы подключим к третьему пину ардуино.
В данном скетче реализована работа датчика вибрации, при которой если датчик улавливает вибрацию, загорается светодиод подключенный к 13 пину ардуино.
Необходимо скопировать программный код приведенный ниже и вставить его в программу Arduino IDE и загрузить этот программный код в саму плату Arduino.

Car knock sensor — function and troubleshooting
Here you will find useful basic information and important tips relating to knock sensors in vehicles.
The knock sensor monitors the combustion process in the engine. Its signal helps the engine control to prevent knocking combustion and therefore protect the motor/engine control. On this page we will provide you with various information, including how a defective knock sensor becomes noticeable, the causes that may lead to its failure, and how it can be tested in the workshop.
Important safety note
The following technical information and practical tips have been compiled by HELLA in order to provide professional support to vehicle workshops in their day-to-day work. The information provided on this website is intended for use by suitably qualified personnel only.

Causes for faulty knock sensors
Check the knock sensor
CAR KNOCK SENSOR FUNCTION : FUNCTIONAL PRINCIPLE
The knock sensor is located on the outside of the engine block. It is intended to record knocking noise in all engine operating states in order to prevent engine damage.
The knock sensor «listens out for» the structure-borne vibrations from the engine block and converts these into electrical voltage signals. The signals are filtered and evaluated in the control unit. The knocking signal is assigned to respective cylinder. If knocking occurs, the ignition signal for the respective cylinder is adjusted in the «late» direction until knocking combustion no longer occurs.
FAULTY KNOCK SENSOR : SYMPTOMS
A faulty sensor can manifest itself in different ways through fault detection by the control unit and the resulting emergency program strategy.
Frequent fault symptoms are:
CAUSES FOR FAULTY KNOCK SENSORS : CAUSE OF FAILURE
Failure can be caused by different reasons:
CHECK THE CAR KNOCK SENSOR : TROUBLESHOOTING
Check the knock sensor: Example OK
TROUBLESHOOTING:
Testing with the multimeter
Check the wiring to the control unit by checking continuity and short circuit to frame for every wire to the control unit plug.
Connect the ohmmeter

Knock Sensor Module Arduino Tutorial
Created on: 13 December 2017
How to use the knock sensor from the 37 in 1 sensor kit for Arduino from Geekcreit, Elegoo, Elektor and others.
This tutorial shows the basic use and testing of the knock sensor module with Arduino. An Arduino sketch shows how to read the knock sensor to determine if it has been knocked or tapped.
Note that there are two different pinouts for the knock sensor module, depending on which kit they are from. See the knock sensor module pinout for more details.
The image below shows the knock sensor module used in this tutorial.
Geekcreit Knock Sensor Module
Knock Sensor Module Circuit
Before continuing, refer to the knock sensor module pinout to determine the configuration of your knock sensor.
There are two different knock sensors and two different ways that each can be configured.
The knock sensor module can be wired to the Arduino using the 10k resistor on the module as either a pull-down or pull-up resistor. A different sketch is required for each different wiring configuration.
Geekcreit Knock Sensor Module Circuit
Below are two circuits that can be used with the Geekcreit knock sensor module. It is recommended to check your module with a multimeter to make sure which pins the 10k resistor (R1) on the module is connected to.
Circuit Connections to Arduino:
The circuit on the left is used with the pull-down resistor Arduino sketch below. The circuit on the right is used with the pull-up resistor Arduino sketch below.
Geekcreit Knock Sensor Module Circuit
Alternate Knock Sensor Module Circuit
If your knock sensor is configured with the 10k resistor connected between pins 1 and 2 of the module, then choose one of the following circuits.
Circuit Connections to Arduino:
Knock Sensor Module Arduino Sketch
Choose one of the following sketches, depending on if you wired the knock sensor module to use the resistor as a pull-down or pull-up.
Both sketches monitor the pin that the knock module is connected to. If a knock is detected (when someone knocks or taps the sensor), the Arduino on-board LED is switched on for two seconds.
Pull-down Resistor Knock Sensor Module Arduino Sketch
Use this sketch with the pull-down resistor circuit. SENSE in the circuit diagram connects to KNOCK_PIN defined in the sketch (defaulted to pin 2 in the sketch).
Pull-up Resistor Knock Sensor Module Arduino Sketch
Use the sketch below with the pull-up resistor circuit. SENSE in the circuit diagram connects to KNOCK_PIN defined in the sketch (defaulted to pin 2 in the sketch).
