I have seen a few inquires about interfacing a D2000 with humidity sensors. For those that might be interested, I wanted to call attention (somewhat self-serving) to an article/project https://www.allaboutcircuits.com/projects/how-to-check-and-calibrate-a-humidity-sensor/ How to Check and Calibrate a Humidity Sensor that has schematics and code using the D2000 and DHT-22 (proprietary serial), HIH8121 (I2C), HIH6030 (I2C) and HIH5030 (analog out) humidity sensors.
