I've recently begun doing a school project. For one of the subsystems , I intend to mount a buzzer and vibration sensor on a walking stick and configure it such that the buzzer sounds when the walking stick falls and hits the ground.
I'm assuming the the impact of the walking stick hitting the ground will cause some deflection on the tip of the vibration sensor which will generate a voltage signal.
The problem is that I cannot seem to get the vibration sensor to work. What I have done was just to connect it to a 5V DC source and a 1K Ohm resistor and measure the voltage drop across it when I push the tip with my finger. However , the voltage drop across this vibration sensor does not change no matter how much I deflect the tip.
I'm using a MEAS MSP-1006 ND vibration sensor.
