I've used these: https://sensirion.com/media/documents/213E6A3B/63A5A569/Data...

That tracks somewhat with what I remember. I was working on process control for an industrial washing machine in a hot and humid environment. I think the extreme temp and humidity is what made it difficult, but those error margins do look great for the cost.
