OVERVIEW:

A new application of MQ-138 semiconductor sensor for breath acetone detection is proposed in this work. MQ-138 semiconductor sensor was integrated to a system which consists of three blocks. This system offers benefits such as portable, fast and easy to operate. Experiments with breath acetone samples from both diabetes and nondiabetes patients validated the accuracy of this system. Based on the measurement results, it was found that as the sensor output voltage increased, the higher blood glucose values measured which means it has been proven that sensor readings of MQ-138 sensor has linear relation to the breath acetone. Therefore, the proposed system has a potential to be used for breath acetone detection in diabetes patients as a new application of MQ-138 semiconductor sensor.


Features:

  • with the signal output LED indication;
  • 2-way signal output (analog output, and TTL-level output);
  • TTL output valid signal is low; (low output signal light, which can be accessed microcontroller IO port)
  • analog output increases with the concentration, the higher the voltage the higher the concentration;
  • aldehydes, alcohols, ketones, aromatic compounds with high sensitivity;
  • with a long life and reliable stability;
  • Fast response characteristics;
  • with mounting holes for easy permanent installation;
  • the probe can plug design for easy testing.
