D3.4 - Power control and app connection via Bluetooth for NDIR-Sensor-applications
M. Ueberschär, Matthias Jung, Falk Liebold · Lectures · 2025
For NDIR gas analysis, a constant emission spectrum of the integrated IR emitter is necessary.This requires the supply of constant electrical power.An electronic circuit is designed that enables the power implemented at the emitter to be set and measured.A digital controller with dynamic parameter determination is implemented in a microcontroller.A mobile smartphone application is created to display measured values and set the reference variable.Bluetooth communication enables cyclic data exchange between the app and the microcontroller.
