描述
Piezo Vibration Sensor – Small Horizontal 薄膜壓電式振動感測器 美國 SparkFun 原裝進口
Measurement Specialties 的 Minisense 100 是一種低成本懸臂式振動傳感器，通過質量負載，在低頻時提供高靈敏度。用於檢測用戶的振動和“敲擊”輸入。當電影向前移動時，會產生一個小的交流和大電壓（高達+/- 90V）。一個簡單的電阻應該把電壓降到ADC電平。也可以用於衝擊感應或靈活開關。帶有可以水平安裝的機器引腳。
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
- 麵包板友好的線索
原廠技術文件與範例
The Minisense 100 from Measurement Specialties is a low-cost cantilever-type vibration sensor loaded by a mass to offer high sensitivity at low frequencies. Useful for detecting vibration and ‘tap’ inputs from a user. A small AC and large voltage (up to +/-90V) is created when the film moves back an forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch. Comes with machine pins that allows for horizontal mounting. We’ve seen this used as great musical inputs. Features:
- Flexible PVDF Piezo Polymer Film
- Wide dynamic range
- Laminated for higher voltage output
- Breadboard friendly leads
