humidity sensor value



  • Hey all,

    i bought a dht-22 sensort and it shows about 20% less that expected (i did the salt test calibration), then i bought a dht-11 sensor and it shows even less, about 30% less than expected. searching the internet i didn't found people having such problems, all i can find that these devices are quite precisie. after calibration the values are ok, but what will happen if humidity drops below 20% ? or maybe it is problem with the library that reads these values ? i'm using the example sketch for humidity sensor.
