Here at SHINYEI, we were the first company to develop and market
a macromolecule electronic humidity sensor in Japan.

Today, we not only produce humidity sensors for scientific measurement, but also for air conditioning and industrial use. We also have a wide range of products for home use. We have also developed a dust sensor to further advance our range environmental sensor.
SHINYEI will continue to develop and improve humidity and dust sensor to meet our customers demands and provide the quality for which we are renowned.
