I have had a bad experience with using a Radio Shack power adapter (1.5V - 12 V 300mA) with the LCD+2 using the onboard female plug to the adapter. It burned...
... If I was doing this project, I would use the Basicx and program the climate controls you are going to use with it. The basicx would only send Raw data back...
Im very new to the world of electronics so forgive my apparent lack of knowledge. Input Devices ============= Could someone point me in the right direction for...
Remember, those cheap supplies are rated for the specified voltage at the specified current. At less power draw, the voltage will be higher, potentially much...
... I ... longivity ... If you do not want to spend too much time on interface circuits, consider using 1-wire sensors from Maxim/Dallas. All you need is a 4k7...
My atmosperic climate control system will place a heavy reliance on fans for temperature control. Typically industry standard fans (@ 100mm for example) are...
I am not sure what you mean by concurrency in this situation. It is asynchronous, and relatively low speed, although some hardware can deal with up to 1M...
[Much removed by moderator] ... exactly what you mean. Thanks for that. Your last paragraph answered what i needed to know. I obviously didn't read what i had...
I have been asked to convert some +/- 10V sensor signals to 0 - +5 volt for use with a Basicx 24. Is there a way to do this without using a 3rd party signal...

... That's exactly what is - an analog -10 to + 10 voltage voltage from an analog sensor. Paul "I've seen the future, and you're not going to like it." --...
... The conversion needs two parts. Firstly, you need to convert the 20 volt swing (-10 to +10) into a 5 volt swing. That's easy - use a voltage divider....
Maybe you should also look at the SHT75 It's cheaper and more easy to mount in a probe. I know a cheap website where to buy them. Let me know if you want more...

... By itself, it doesn't. Once you've limit the swing to +/-2.5 volts and shift it up by 2.5 volts, the signal will always be 0-5V unless there is a...
