Re: Maplin station range issue

Alan, As originally planned, the remote is a pain to get to, but that's the way these things work out, I was trying to "persuade" the user to put it somewhere more accessible, based on my own experience of things like spiders in the rain system, changing batteries, and general aggravations...

Re: Maplin station range issue

Here's a picture of a vertical dipole radiation pattern. It's shows what Jim means. So add some walls, floors, roof and ceiling and there's probably not much signal left for the receiver to pick up. https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcT7qN3HJR3iB_xS_VYzMXrpIc_xf9mJSownIPg_PeNlzwyr...

Re: Maplin station range issue

If the transmitter is almost directly above the receiver (which is how it sounds from the description) then each could be in or near a null in the other's aerial response. Try tilting the transmitter and receiver away from their normal positions and see if that makes a difference. Jim, There's an o...

Re: Maplin station range issue

Extend the cables and bring the transmitter to just outside the window this is what I did but for a different reason also makes changing the batteries easy.Alan That's beginning to look like an option, I was forgetting that I've got a crimp tool for RJ11's so not the most difficult task in the worl...

Re: Maplin station range issue

Yup, Tile roof, then 2 floors, though there's not a lot of blockwork in the line between the sender and receiver, so I'm hoping that it's just the batteries are weak, if it's not, then getting it to perform could be "interesting", based on earlier experience at other locations. I have a su...

Maplin station range issue

Hi Folks, Put a "standard" Maplin station up for a friend earlier in the week, it's on a pole attached to a chimney that's 2.5 floors up from where the base station is supposed to be going, and that's the problem, if the base station is on the window cill on the ground floor, it's not seei...

Re: I spy with my little eye....

A very special weather station that may well be something to do with one of the university colleges or similar in the Bristol area, if I am seeing what's there correctly, there are effectively 2 weather stations there, one of them a traditional wind direction and wind speed sensor, and the other, if...

Re: Hall effect sensor for wind vane, or ultrasonic sensors

Indeed, as Steve (Loft) pointed out, those ultrasonic wind (anemometer/wind direction) sensors are, on average, the price (or above the price) of a good/high quality complete weather station... :shock: Steve (the Irish Steve :) ), during my searches to find additional information about ultrasonic w...

Re: Hall effect sensor for wind vane, or ultrasonic sensors

The other option that was interesting, but horribly expensive in the commercial form is a device that's using 3 or 4 ultrasonic sensors to measure both wind speed and direction in the one device, and there are no moving parts with it, which has to be attractive. I'd like one of these. No, I don't w...

Hall effect sensor for wind vane, or ultrasonic sensors

OK, here we go. I have an (Maplin) FO 1080 station that's been on the roof for a couple of years, and it recently stopped recording rain, which is the main reason I need the station, as it's my early warning of the danger of flooding. I've also been casting roung the threads here recently, and come ...

Re: WH1080 rain sensor

Several possibilities that might be happening. There may be restrictions on the movement of the tip bucket, the favourite is spider's web, which is preventing correct operation, or due to accumulation of debris or similar, it's not tipping to full travel. Check that it's not sticking on the pivot sh...

Re: Weather related sensor

Hi Not a solution I'm afraid just a suggestion which might influence the design. It would be useful to know the rate of change of level and possibly the rate of flow. But a suggestional also - a rheostat with a long arm attached to a float (though there would be a lot of 'bounce' in turbulent water...

Weather related sensor

Folks, It's not for a weather station, but very much weather related, and will end up being used alongside a weather station feeding into a logging PC. I need a depth sensor, so that I can closely monitor rising water levels in a stream that runs through the garden, for all sorts of reasons, it caus...
