is there any water proof digital temperature sensor available.We need it for Anveshan project.I found one popular sensor DS18B20 Digital temperature sensor.But if analog devices having such sensor then it would be great for us.
Here are some details required by us.
Resolution 10-12 bit
Temperature Range: -15 to 100 Degree Celsius
±0.5°C Accuracy from -10°C to +85°C
Such accuracy level can be achieved with ADT7310/ADT7410 digital output sensor (16-bit) for the range you mentioned. However, for submerging it into water some treatment would be need on the system level application/product to avoid water coming in like including in an hermetic probe or so. Something similar was done in the past with AC2626 but using AD590.
Currently some moisture test at a certain humidity levels can be done in the IC, but totally inmersed is another thing.
