Sensiron Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. And, finally we have some that have 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.

Unlike earlier SHT sensors, this sensor has a true I2C interface, and (bonus!) even with two address options. It also is 3V or 5V compliant, so you can power and communicate with it using just about any microcontroller or microcomputer.

Such a lovely chip - so they spun up a breakout board with the SHT31-D and some supporting circuitry such as pullup resistors and capacitors. Each order comes with one fully assembled and tested PCB breakout and a small piece of header. You'll need to solder the header onto the PCB but it's fairly easy and takes only a few minutes even for a beginner.

    The sensor has so far survived up to 99% relative humidity in the tropics and seems to respond nicely above 90% when other sensors fail or die. I don't know yet how well the PTFE filter will protect it from moisture but nothing else I've tried would've survived the last week's humidity. I coated the entire rest of the board in conformal coating after soldering the wires on to hopefully protect the rest of the PCB.

    It may not be quite as accurate as a Bosch BME280 and lacks the BME280's pressure sensor but they can't survive *any* moisture which makes them problematic for weather sensing. In the end I've ended up leaving BME280 in place with a dead humidity sensor as it still does pressure and temperature nicely. (Posted on 5/02/2018)
