Product Introduction
The SMD1015 acetone gas sensor is a MEMS micro gas sensor developed based on semiconductor materials and can be used to detect the acetone gas content in exhaled breath gas.
The acetone sensing material is developed and made by IDM independently. When acetone gas reach the sensitive material, the conductivity of the material will change. A specific test circuit can be used to convert the conductance change into an output signal corresponding to the gas concentration.
Main Applications
It can be applied to the detection of acetone content in human exhaled breath gas especially for rapid disease detection.
Sensor Characteristics
It adopts MEMS technology and semiconductor materials, and has the advantages of small size, low power consumption, high sensitivity, fast response recovery, simple driving circuit, good stability, long life, solid structure and good shock resistance.
