How does a vape know when you hit it?

Have you ever wondered how your vape pen senses when you take a hit? It's actually a pretty fascinating process involving sensors and technology. Essentially, when you inhale on the vape, it activates a sensor that detects a change in air pressure inside the device. This sensor is typically a small, yet powerful, component called a Flow sensor or an air pressure sensor. It's designed to detect even the slightest changes in air pressure, which occur when you inhale on the vape. Once the sensor detects this change, it sends a signal to the vape's battery and heating element, telling them to activate and produce vapor. So, in a nutshell, the vape knows when you hit it by sensing changes in air pressure inside the device, thanks to its sophisticated flow or air pressure sensor.
