If I put a low pass filter (RC) between the relay and counter, should it help? What values of R and C do I have to use for a relay with a frequency of 50ms open? I've used R=330ohm and C=4.7µF (cur-off=102hz) but the counter counts less than the relay-pulses.

I will make some pictures when it stops raining and connect the sensor like sda said. another dataseries: 1050 1322783518 1200 1322783533 899 1322783549 1120 1322783564 1132 1322783579 1042 1322783594 762 1322783609 778 1322783625 763 1322783640 754 1322783655 492 1322783670 1 1322783730 <--...

See the image for my connection with the sensor. When count with a low frequency, there is no problem. When the frequency becomes higher, then the problem occured.

Thanks, that seems likely. Any idea how to solve the relay chatter?

I have a dual counter connected with a relay that can "click" with a maximum speed of 10/second (http://rainsensors.com/ in "drop detection" mode). However, when I see the history of the counter, I see usually more than 50counts/second. What can be the reason of this unrealistic values of the...

I have not a Temp08/05. I only use the 1-wire USB connector to my linux-pc.

A question somewhat related to this topic: I have also a lightning detector and read it with owfs. I get values of 67404123, 2285054301 voor counter.ALL (counter A en counter B). Even if I disconnect it from the system and removes the battery, it gives me these values. How can I reset the...

Any news about the new moisture sensor?

I've running the hobby-boards sensors since 3 months. But since 3 days, I cannot read the sensors anymore. I use OWFS and it see all the sensors but for reading the values, it gives me "Invalid Argument". I disconnected everything en reconnect it but same problems.

Thanks. I purchase a HB-case with my HB-UV board. Definitely, we have no UV-strength of 7 at this time of the year, even in summer it is hard to get such a UVI. I will test it tomorrow and else I send a mail to hobby-boards.

I've just received an 1wire UV sensor from Hobby Boards. I installed this and see the UVI isn't calibrated: * At night, I have an UVI of 0.4-0.6 * In the morning, at sunrise, the UVI increase relatively fast to more then 1. * In full sun, I receive sometimes more then 7UVI while the max today is...

Thanks, Is there any knowledge about the function to calculate W/m² from the voltage? (y=ax+b or logaritmic,..?) It's quite expensive to buy an lux-meter of something, just for calibrating the solar-sensor.

I want to buy an temp/solar from Hobby-boards for extending my weather-station. I will be my first 1 wire component so I want to get more information before I buy such system. * When I connect the solar to my computer, what's the output I get? Is it W/m² or just an voltage? Is there a way to...
