As always each has advantages/disadvantages. I've been playing around with both this weekend. The accelerometer seems to work fine if you can give it a good supply and you can read lots of samples and process them to reduce some of the jitter and noise. The Electrolytics take a bit more working with (more pins and you need to take care over the way you drive them). But you probably have more control over the characteristics (you can get different types of fluid, different sizes etc.). I think that if you want to measure really small angles of tilt then the electrolytic ones are the way to go, but for ease of interface the accelerometers are better. Just my thoughts anyone else want to join it? Andy BTW: I got my sensors from Skip Asay of www.rcboats.com which he let me have as a favour, but www.aositilt.com seem to have something that looks very much like the sensors I use. ----- Original Message ----- From: "M Ore" To: Sent: Friday, October 20, 2000 8:32 PM Subject: Re: [PIC]: Using 2 CCP: Compare failed if Capture event the same time > Hi, > Andy you mentioned you were doing this type of thing with Electrolytic > tilt meters.
