This Titan Astro sensor board is based on the famous Sensirion SHT31-D sensor, providing humidity and temperature readings via I2C (QWIIC) to the SkyCamOne HAT.

We've designed this extra small breakout board so it can be easily fixed with a screw or clip. We've placed the sensor in a thin section of the board on purpose, so you can stick it through an as small as possible hole into your camera dome.

Sensirion Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get, with a true I2C interface for easy reading. The SHT31-D sensor has an excellent ±2% relative humidity and ±0.3°C accuracy for most uses. We use the version with a PTFE filter, it'll stay clean while still allowing humidity measurements to work.

Remember to get yourself a QWIIC cable and maybe a SkyCamOne HAT?

Note: You may get an off-white or black JST connector.
