Experimenting with the pressure sensor from a disposable vape - #2 of 3

More experimentation with the pressure sensor from a disposable vape. The device has three connections, an LED, a vacuum sensor.

As seen in video #,1 when power is applied to Red (Vcc) and Black (Gnd) connections, the integrated ASIC flashes the led 3x to signal it has powered up.

When the sensor experiences a drop in ambient pressure, the integrated ASIC detects the change and connects the load line (blue) to Vcc and illuminates the LED.

In this video we connect our multimeter to between load and ground to verify
