Product Features

This board combines an ambient temperature sensor and a humidity sensor and connects to two analog inputs.
Product Description

Measures Relative Humidity from 10% to 95% with a typical error of ±2%RH at 55% RH.

Measures Ambient Temperature in the range of -30°C to +80° C with a typical error of ±0.75°C in the 0°C to 80°C range.

The temperature sensor component is rated at -40°C to +100°C, but the other components on the board, the connector and the cable are rated at -30°C to +80°C. In a fast prototyping environment the temperature sensor board can be pushed to the ratings of the sensor component, but you should use the lower temperature ratings if you plan to use the 1125 in a commercial application.
