Check Your Cold Drip Coffee Through BLE Remote in Front of Your PC

Youc can monitor the process of coffee making during deskwork.

We use ultrasonic sencor to monitor the distance between the semcor and the ice and transmit it to the computer and cell phone with Bluetooth. The more the ice melts, the further the distance, when you see the distance of 12 on the display, it means the ice is completely melted, so you can add ice or enjoy your coffee!
