BLE Touchless Door Control Device with Qtouch

remote control of another device via BLE. Control to open the door without touching it with the Qtouch button

Droid Technologies designed and developed a BLE-based touchless control device for remote operation of external equipment, including automatic doors and access control systems.

The device is based on the Nordic nRF52810 and uses Bluetooth Low Energy (BLE) for reliable wireless communication. It integrates high-sensitivity QTouch capacitive buttons, capable of detecting user interaction from a distance of several centimeters without direct physical contact.

The solution is suitable for touchless access control, smart buildings, healthcare environments, public spaces, and industrial automation, where hygiene and convenient contactless operation are important.

Droid Technologies delivered hardware design, PCB development, embedded firmware, BLE integration, capacitive touch sensing, sensor tuning, and complete system testing.

Key features and engineering scope:

• Nordic nRF52810 BLE MCU
• Bluetooth Low Energy communication
• Touchless door and remote device control
• High-sensitivity QTouch capacitive sensing
