I am using a Raspberry Pi 2 model B and the sensor is marked v1.2. Visually I have confirmed it is the standard version, not pro, by matching it to the image at http://www.seeedstudio.com/wiki/Grove-_Temperature_and_Humidity_Sensor. The board looks the same except for printed words. I have verified I am running firmware version 1.2.2
I am working thru the examples in the GrovePi+ starter kit booklet and things have been great until I got to this sensor. I am using the GrovePi/Projects/Home_Weather_Display/Home_Weather_Display.py script and the values are incorrect. Initially they read like this:
temp = 563.2 C humidity = 947.2 %
and when I blow over the sensor with humid breath it gradually moves over several seconds to:
temp = 640.0 C humidity = 1459.2 %
Over time it will return to the lower values. So I conclude that the connections and port values are correct, but the readings are obviously wrong.
Am I using the wrong script? Al the others appear to be for the pro version.
Do I need to update/change drivers?
Is there a problem with my sensor?
