|Console Temperature & Humidity Sensor|
|Sensirion SHT 11|
I'd say we have a match. AJP & A5Z are just lot codes according to the datasheet. Follow this link to find the details of the Sensirion SHT11 sensor used in the console, and this link to the datasheet. I have a sneaking suspicion that the ISS uses the same sensor, but I'm not about to tear it apart to find out. It would make sense though. The measly -40C bottom end of the outdoor unit matches the lower limit of this chip. Grrxyn left a comment on an earlier post noting that the Davis design doesn't follow the datasheets recommendation of thermally isolating the sensor from the main circuit board. So if your console seems to be reading a bit hot, now you know why.
