My 1-wire ADS Anemometer looks to be faulty with about half of the directions not registering. Reed switches a possible cause according to Eric from Hobby Boards. With Eric winding up the business i’m wondering what are my options now if i want to replace the unit rather then repair? It’s only for direction i use the ADS as i use an Inspeed Vortex for speed. I know Inspeed do a Wind Vane but 130 bucks + PP is a bit out of my budget.
Yes Brian i have tested the voltages and the following degrees are in range, 0, 45, 90,135, 158, 225, 315, 338. Most notably from testing i found that when pointed West 270 i get a Voltage of 9.9 which is quiet a bit away from the 0.89-0.95 expected. I have been in contact with Eric from Hobby Boards and he thinks it could be reed switch problems. Looking back now to the time i got the unit it never showed about half the directions so probably was faulty when i got it.
Yes it seems to be the case Brian, I see the correct voltages for the directions i posted previously and 9.9v for the remainder. I enclose a pic which is the same as the ADS unit i have.
Just an update on this, it would seems that the Fine Offset wind vane works differently to the ADS 1-wire version even though they look identical. Only option now seems to be to go down the repair route.
Eric from Hobby Boards thinks it could be a faulty reed switch on the wind vanes circuit board. So i will probably investigate this further as it seems there are no replacement units out there.
The ADS is a modified FO/WH1081 sensor with Dallas DS2423 and DS2438 1-Wire chips.How Eric did this i don’t know. Will have to take down the unit from the roof. Also the WH1081 uses resistance to measure directions rather than voltages as the ADS does.
