I have one of these that I've recently tried to hook up but I don't seem to be getting good values off it.
Running on 3.3v on a Firebeetle ESP-32E I consistently get readings around the following off the analog pins:
Temp: 1303
Humidity: 1765

Based on the example code this means:
Temp (C) = -66.875 + 72.917 * (1303 / 1024 * 3.3) = 239.31
Humidity (%) = -12.5 + 41.667 * (1765 / 1024 * 3.3) = 224.50

So I'm looking at around 240'C and humidity of 225%. Not sure on the humidity here but temp should be about 16'C.

Any idea what I might be doing wrong or is my sensor probably cooked?
