Sparkfun Piezo Vibration Sensor – Large with Mass 壓電振動感測器

商品說明

Piezo Vibration Sensor – Large with Mass 產品介紹

Measurement Specialties的這款基本壓電傳感器通常用於彎曲，觸摸，振動和衝擊測量。當膠片前後移動時，會產生一個小的AC和大電壓（高達+/- 90V）。一個簡單的電阻應該使電壓降到ADC電平。 也可用於衝擊感應或靈活開關。

配有可焊接的壓接針和附著在針尖上的質量塊。<這個質量增加了對運動的敏感度。

特徵

• 柔性PVDF壓電聚合物薄膜
• 寬動態範圍
• 層壓更高的電壓輸出
• 0.1“的麵包板

– Connect a 1Mohm resistor across the Piezo sensor’s pins.
– Connect one leg of the Piezo to GND
– Connect the other leg of the piezo to A0

Vibrations on the Piezo sensor create voltags, which are sensed by the Arduino’s
A0 pin. Check the serial monitor to view the voltage generated.

Development environment specifics:
Arduino 1.6.7
******************************************************************************/
const int PIEZO_PIN = A0; // Piezo output

void setup()
{
Serial.begin(9600);
}

void loop()
{
// Read Piezo ADC value in, and convert it to a voltage
int piezoADC = analogRead(PIEZO_PIN);
float piezoV = piezoADC / 1023.0 * 5.0;
Serial.println(piezoV); // Print the voltage.
