Sht11 - 1139,471

Hi All,
seeing some strange behaviour with my SHT11 temp/hum sensor.

All connections are solid. Code works great.

problem: Intermittenly the sensor returns a temperature of 1139 deg F, and a humidity of 471%. This only seems to happen once the ambient temp is over 90 degrees F.

any ideas whatsoever?????

    Assuming you use some formula to calculate temp and hum

    from sensor reading values, I suggest you calculate by hand expected

    temperature results for sensor reading values that are supposed

    to calculate around 90 degrees F (take 87-93). There may be a discontinuity in

    your formula regarding some reading values.

    regards peter
