Aiming at the problem that microfluidic chip detector lacking a software control system is very difficult to operate

take the Bluetooth module HC—06 as the interface and the Android smartphone as the platform

design a human-computer interaction system of microfluidic chip detector

aiming at enabling users to operate the microfluidic detection equipment simply and naturally through this system

so as to achieve simple and rapid detection. The system adopts STM32 as the main controller

and the control Bluetooth module sends the microfluidic chip signal obtained by I/V conversion

filtering rectification

offset and amplification to the mobile phone for real-time display

analysis and storage. At the same time

the mobile phone can also send relevant instructions to urge the detector to complete different functional operations. The system has been applied to the self-made microfluidic analysis detector

and the human-computer interaction effect is good

which improves the operability of the detector.
