Fermion - formaldehyde sensor - HCHO - MEMS - 0-3 ppm - DFRobot SEN0563.
Studies have shown that long-term exposure to high concentrations of formaldehyde may be associated with certain types of cancer, especially nasopharyngeal cancer and leukemia.
What is formaldehyde and where is it found?
Formaldehyde, also known as formaldehyde (chemically HCHO), is a colorless gas with a pungent odor, used mainly as a preservative, also found in the production of building materials and household products. It is an ingredient of products such as paints, adhesives, chipboards and textiles. Formaldehyde also occurs naturally in the environment - it is a by-product of certain metabolic processes.
It has properties that may make it harmful with long-term exposure - it will result in irritation of the respiratory tract and eyes.
Suggested use of the sensor
- Disinfection and sterilization
- Production of other chemical compounds
- Fabric finishing (to protect against shrinkage)
Special features of the sensor
- It has a modernized MEMS system for precise HCHO measurement
- Compact dimensions (13 x 13 x 2.5 mm) allow for easy integration with other project components.
- It has low energy consumption.
- Provides precise and stable value reading.
- It has high sensitivity and short response time.
Precautions during use
- Before using the sensor, remove the protective film from it.
- Avoid using the sensor in an environment where it will be exposed to high concentrations of corrosive gases (such as H2S, SOX, Cl2, HCl, among others).
- Protect the sensor from contamination with alkalis, alkali metal salts and halogens.
- Avoid long-term exposure of the tile to unfavorable environmental conditions (such as high temperatures, high humidity, high pollution).
- Do not expose the module to water.
- Do not expose the module to vibrations, impacts or falls from height.
- Do not test the module on systems that involve personal security concerns.
