SMD1015 Detection Of Exhaled Content Using Gas Sensor
Applications:
The SMD1015 gas sensor is primarily utilized for detecting gas. It
finds extensive use in various fields:
- Medical Field: It can be employed in breath analysis devices to
detect levels in exhaled breath. Changes in concentration in breath
can be indicative of certain metabolic conditions, such as in the
monitoring of diabetes, where abnormal levels may occur.
- Industrial Safety: In industries where is used as a solvent or in
manufacturing processes, this sensor helps in monitoring leaks to
ensure workplace safety and prevent potential hazards.
- Environmental Monitoring: It can be integrated into environmental
monitoring systems to detect emissions from industrial sources,
contributing to the assessment and control of air pollution.
Features:
- High Sensitivity: With a resolution of 0.1 ppm and a sensitivity of
R₀ (in air) / Rₛ (in 1 ppm C₂H₆O) ≥ 1.5, the sensor can accurately
detect even low concentrations of, enabling precise measurement.
- Wide Detection Range: It can detect within the range of 0 - 500
ppm, making it suitable for both low - concentration and relatively
high - concentration detection scenarios.
- Good Environmental Adaptability: The sensor operates within a
temperature range of -20 - 55 °C and a humidity range of 10 - 95%
RH, allowing it to function reliably in various environmental
conditions.
- Fast Response and Recovery: The response time (T₉₀) is less than 30
seconds, and the recovery time (T₁₀) is less than 60 seconds,
ensuring quick detection and recovery after exposure to gas.
- Long Service Life: With a service life of ≥3 years, the sensor
provides long - term and stable performance, reducing the need for
frequent replacement.
- MEMS Technology: Based on MEMS (Micro - Electro - Mechanical
Systems) semiconductor technology, the sensor has the advantages of
small size, low power consumption, and high integration,
facilitating its integration into various devices.
