I bought a small mounting kit from B&Q for £7 (I'll post link below and take a photo of it installed). It tells you to mount the wind sensor on the side of a fence or wall, which would obviously block all wind from one direction and mess up the readings. I don't like how the instruction manual describes placement of the sensors. I like that all the sensors are independent and wireless. I assumed this was just variation with my unit, but it's interesting another user here has the same readings. However using the Cumulus offset calibration feature the values can be corrected and remain consistent. The sensors seem to be a little off (as described in this thread), even my £20 Aldi ASCOT weather station is more accurate. As such I have all the data logging I could want. I have an old Asus EEE netbook that is now running Cumulus 24/7. This is my first venture into wind and rain measurement. Now that you've done some calibration, how are you finding it? They're going for quite a good price at the moment, so aside from the lack of a data logger, I'm wondering if they are a good buy as an alternative to Fine Offset stations.īefore this station I only had generic temp/pressure/humidity sensors. Steve wrote:I don't think many people have these, which is probably why no help was forthcoming. Be aware that when you change this setting that it will not update your pressure value until the next reading. I had to put in a setting of 80m (which is 40m above my actual height) to get it to give a reading that matches my local stations. Instead of just setting your local pressure as a reference it wants you to put in your altitude above sea level (in meters). The setting you describe is for calibrating the barometer.
This is the reason I started the thread and ultimately answered my own question. I'll try and get it to the roof sometime. Only got it mounted above the roof of my shed so about 3m and house to the North and South. Wind, I'm well under due to siting issues. The airport doesn't seem to report rain, so no idea how I'm doing on that, but I am getting readings (5.1mm in the last hour) My last reading is showing 7.3 compared to the airports 8 My nearest station is Blackpool Airport (.5mile away) and my pressure reading on the few times I've compared is showing about 5mb below the airports.Īirport seems to show the temp as a rounded value, so I'm reading a little below. Think you use 'select' to get to get the cursor to the baramoter/rain/uv section then press 'mode' to select the baramoter setting. Not got the manual to hand so not sure what it does, all I can remember is that it changes in steps of 10. There is a setting on the console to change something to do with the pressure setting. My first weather station so cannot compare it to anything else.
