STS31-DIS

The STS-31 mission, part of NASA’s Space Shuttle program, launched on April 24, 1990, using the Space Shuttle Discovery (OV-103). This mission is best known for deploying the Hubble Space Telescope, a significant advancement in astronomical observation.
Hubble has since provided valuable data and images, revolutionizing our understanding of the universe. STS-31 involved a crew of five astronauts, including mission commander Loren J. Shriver and payload specialist Charles D. Walker. The mission lasted approximately five days, during which astronauts conducted a series of experiments and ensured successful deployment of the telescope into low Earth orbit.
The STS-31 mission was a critical milestone in the field of astrophysics, enabling groundbreaking discoveries related to cosmic phenomena, galaxy formation, and the expansion of the universe. The success of Hubble has had a lasting impact on both science and public interest in space exploration.

Equivalent products to the STS31-DIS chip include the SHT30, SHT31, and SHT35 from Sensirion, as well as the BME280 from Bosch. These sensors offer similar functionalities in measuring temperature and humidity, with varying accuracy and features. Always check specific datasheets for detailed comparisons and compatibility.
