Perhaps it is an SHT31, but with Analog output, instead of digital.
Something like this, I think:

The SHT3x humidity sensor series consists of a low-cost version with the SHT30 humidity sensor, a standard version with the SHT31 humidity sensor, and a high-end version with the SHT35 humidity sensor. All these exist with digital output.
This one, is a little expensive (ships from USA) but includes a filter membrane to protect against environmental factors such as dust, water immersion and other particle ingress. This makes it perfect for harsher environments in which most other humidity sensors would fail.
