Sensitive Vibration Switch Sensor With Demo Code For Arduino
Vibration switch module for arduino with demo code
Description:
Introduction
Vibration switch is mainly used in electronic toys, small appliances, sports equipment and a variety of anti-theft devices and other products. Vibration switch because they have a flexible and sensitive trigger, and become an integral part of many electronic products, electronic components.
Specifications:
Note:
1, the scope: small current vibration switch. Products sloshing around in the horizontal electrical changes produced in low current circuit (secondary circuit) with a vibration sensor.
2 Operating temperature range: 5 ~ 70 º C Humidity 85 [%] or less.
3 Storage temperature range: 15 ~ 45 º C Humidity 80 [%] following storage for 90 days.
4 Test Status: Test and test if no special provisions under the following standard conditions Temperature: 5 ~ 35 º C Relative
Humidity: 45 [%] to 85 [%].
The use:
We first look at his specific pin functions
Also the only three leads, connect the power, after a good ground, we received a digital signal output port on
Can be used (we then use the 7th).
Fourth, the module test
Hardware Requirements
Arduino controller × 1
USB data cable × 1
Vibration switch module × 1
Led indicator × 1
Here, everything is ready, we will now begin to build a test circuit bar
Here we use it for a simple application that senses the vibration switch vibration LED is lit
Lights to warn it, there are unusual circumstances happen? ?
Well, look at the code under test it, maybe you can guess what will happen. . . . .
int ledPin = 13; / / signal indicator output pin;
int switchPin = 7; / / vibration switch input;
int value = 0; / / latch vibration switch key;
void setup ()
{
pinMode (switchPin, INPUT); / / Define port attribute;
pinMode (ledPin, OUTPUT);
}
void loop ()
{
value = digitalRead (switchPin); / / read the key state;
if (HIGH == value) / / there is vibration;
{
digitalWrite (ledPin, HIGH); / / steady state, led other off;
}
else
{
digitalWrite (ledPin, LOW); / / lit led lights;
}
}
The program features: Let vibration switch vibration, you can see the arduino board 13 pin led lights are lit for a while,
When the shaking soon will light or blink when.
