Recently an article was published in Design News about digital humidity sensors offered by Servoflo.
Typical problems of traditional integrated sensor solutions include poor accuracy, unstable behavior around the measuring range limits and unsatisfactory chemical resistance against contaminants. Additional limitations are lack of dew formation resistance, inadequate long-term stability and failure during load spikes.
This article provides technical details about how these problems are solved with new digital humidity sensor technology. In depth details about design features and manufacturing techniques are discussed. Topics include ASIC functionality and design, construction, and what this means for the functionality of the humidity sensor.
Anyone who is considering designing in a digital humidity element should take a quick look at this topic. Please feel free to post a comment or question.
