Re: Intermittent wind speed in Fine Offset WH1080

Hi, I didn't respond to this particular thread because most had already been said before. Just to clarify, as a test you can plug the short anemometer cable directly into the Rain socket and rotate it a few times. But note that it may take up to 48 seconds before the reported "Rain" sudden...

Re: WH3081 has stopped receiving readings, but UV & solar still work

Hi, AU$34 is probably broadly consistent with the price from a retail seller, i.e. one offering full support and some guarantee that it will meet your requirements. The rather simpler WH1081 transmitter is sold by our "Maplin" retailer for £15, shipped and with a free-return policy (but ot...

Re: WH3081 has stopped receiving readings, but UV & solar still work

Hi, Replacement "external transmitters" are certainly "available" but sometimes at a price that is too high to be worthwhile. Also, there are numerous versions which all look very similar: Firstly, the carrier frequency may be 434 MHz, 868 MHz (mainly Europe) or 915 MHz (USA) but...

Re: WH3081 has stopped receiving readings, but UV & solar still work

Hi, The "Solar Pod" has its own microcontroller which generates a separate data packet which is passed on to the radio transmitter in the main "external unit". So it's quite possible for only one of the two controllers to "crash" (or the critical message-timing to becom...

Re: Replacement for the standard rain gauge ... ???

Hi, I did experiment with adding a 14 cm diameter plastic funnel above the normal FO rain sensor with the aim of achieving 0.1mm per tip. But to be honest it was rather a failure because the rain collected in beads in the funnel (even though it had much steeper sides than the FO) and didn't give an ...

Re: WS1080 indoor temperature sensor?

Hi, Fine Offset have changed the internal hardware of the "WH1080" several times, including the T/H sensor. You appear to have copied the photo from the 2009 ".. Inside of..." thread. Does your sensor daughter-board (in the middle, below the barometric sensor) look exactly the sa...

Re: Oregon WMR89

Hi, The wind and rain sensors are available from Maplin at quite reasonable prices and are all compatible. However their (434MHz) transmitter is out-of-stock and wouldn't support the (inessential) Radio Clock of the 1080. Clas Ohlson also have the latest (blue backlight) version of the 1080 at £10 l...

Re: Air Pressure Sensor - WH1080

Hi, Quite an old thread (however the ".. inside of WH1081" thread is even older), but I happened across this specification for the pressure sensor used in at least SOME of the Fine Offset Consoles. They do appear to be available as "spares" on the "open market" (ebay, A...

Re: Photos of the insides of Fine Offset sensors.

Hi, Possibly worth a try, but it could be a SHT/DHT 15 or 21, or AM2301, etc.. First thing to check is if it's using 2, 3 or 4 wires/pins to connect to the main board. That may help determine if it's an I2C, SPI or a "one-way" data bus. The sensor is probably made by the Chinese company &q...

Re: Is it possible to change the Humidity-Sensor on the circuit board?

Hi, The Temperature-Sensor works exactly, but the Humidity-Sensor is worn. There have been several different types of humidity sensor fitted in these stations and I thought the more recent versions use the same sensor for temperature and humidity. However, it should still be on a small module or &qu...

Re: Photos of the insides of Fine Offset sensors.

Hi, The distance from the PCB to the center of the battery contacts is 7mm on mine. I think you mean from the inside of the "battery box" plastic case, because AA cells are exactly 14 mm in diameter (they're also known as "14500" cells, i.e. 14 mm in diameter and 50.0 mm long). S...

Re: Weather Station Recommendations

Hi Andy, Need the usual measurements including UV .... What for? The Davis sensor alone for that costs (much) more than your total budget. As Ray says, there really isn't anything much at your price point. So take a look at the Weatherduino Project which now includes UV and even Air Quality Monitori...

Re: The maplin wireless wether station radio link fault

Hi Dave, Welcome to the forum. Sorry we didn't respond yo your previous post but there really isn't much to add to the answers there or elsewhere on the forum. But to summarise; you must power-down the Console (remove and replace the batteries and USB cable) to resynchronise the transmitter after re...

Re: Ambient WS-2080 RF Reset?

Hi, 433 MHz is the primary ISM "License Exempt" frequency in Europe (and much of the World) but barely "LegaL" in USA. The "official" frequency is 915 MHz, but it appears that Fine Offset may (still) use a different Wireless Protocol (FSK) for that frequency. The Fine O...

Re: Ambient WS-2080 RF Reset?

Hi Bob, I've not dismantled my 2080 (yet) but you may get some "clues" about the general method of construction from the two "...insides if..." sticky threads in the Fine Offset section. The transmitter uses a tuned loop antenna printed on its PCB, but the Console antenna is prob...
