# UiRaS 2.0 beach water temperature sensor data This directory contains data of UiRaS (UimaRantaSensori) water temperature sensors, which are located at several swimming places in Helsinki. Data is visualised in https://uiras.fvh.io and visualisation's source code is in https://github.com/ForumViriumHelsinki/UiRas All data is downloadable in CSV format (file: uiras-all-data.csv), which looks like this sample below: time,readable_time,analog1,analog2,batt,lat,lon,rssi,temp_in,temp_out1,temp_out2,temprh_rh,temprh_temp,dev-id 1591255827157,2020-06-04T07:30:27.157000Z,0.012,,5.225,,,-108,23.33,17.62,,,,70B3D57050001AB9 1591255982452,2020-06-04T07:33:02.452000Z,,,5.271,,,-112,25.69,16.25,,,,70B3D57050004FE6 1591256270808,2020-06-04T07:37:50.808000Z,,,5.317,,,-94,9.99,13.31,,,,70B3D57050004DF8 1591256312824,2020-06-04T07:38:32.824000Z,,,5.311,,,-95,21.37,17.25,,,,70B3D57050004E0E 1591256428127,2020-06-04T07:40:28.127000Z,0.012,,5.225,,,-110,23.01,17.62,,,,70B3D57050001AB9 1591256605491,2020-06-04T07:43:25.491000Z,,,5.324,,,-108,19.52,17.12,,,,70B3D57050001BBE 1591257029164,2020-06-04T07:50:29.164000Z,0.012,,5.225,,,-104,22.9,17.56,,,,70B3D57050001AB9 1591257102831,2020-06-04T07:51:42.831000Z,,,5.293,,,-94,18.81,13.37,,,,70B3D57050004D86 1591257279634,2020-06-04T07:54:39.634000Z,,,5.282,,,-100,20.46,15.18,,,,70B3D57050004C07 1591257623515,2020-06-04T08:00:23.515000Z,,,5.337,,,-86,21.01,13.62,,,,70B3D57050004FB9 Most interesting columns are: readable_time = timestamp with timezone in ISO format temp_out = temperature probe's reading (water) dev-id = sensor's identifier Other columns: temp_in = internal temperature in sensor case (not very accurate) temprh_rh,temprh_temp = external air RH and temperature probe data (not widely used) rssi = LoRaWAN network RSSI, if value is near -120 the network is unreliable All available metadata is in json file uiras-meta.json. There is one object for all sensors, like this: "70B3D57050004DF8": { "name": "Vasikkasaari", "lat": 60.1523297, "lon": 25.0158648, "servicemap_url": "https://palvelukartta.hel.fi/fi/unit/50903", "site_url": "https://www.vasikkasaari.org" } File uiras2_v1.json contains data of last 2 weeks and it is used by https://uiras.fvh.io site.
