I got both WS-5300 & WS-2080 inside SRSLX100 from ambient weather I mounted both the same location same height 2m above rooftop , the reading in daytime are identical for example both gives 30.8 with no calibration , in night time there is a big difference the WS-2080 always gives a higher readings where WS-5300 more reasonable comparing it to the min-max mercury thermometer inside stevenson box and nearest offical weather stations for example today minimums
WS-2080 : 19.2
WS-5300: 17.2
Nearest station : 17.3
this happened everynight though i made different mounting plans, added a fan to SRS100LX following a post in web, put inside a stevenson screen with standard shield and without it
important thing that our area in daytime has steady breeze 20-35 km/hour, and we have calm nights no more 10 km wind
appreciate any suggestions
