I am reading this now just what I wanted.
always interested in diy pic stuff I measure temp with a thermister but it

more reliable

I'm fairly certain they are LM35DZ, and I got them from Farnell.
It's not 100% because that's based on teh fact that I've done it by
checking in my bits box and found a packet claiming to contain 5
"LM35DZ ic-precision temp sensor", and actually containing only one,
and I think I bought a couple of spares for design development.

It might be farnell part number 409-091, and if so I expect a trip to
teh web site will yield a data sheet fairly easily.

I thought about thermistors, but this sensor with its linear output
and an appropriate couple of resistors on an op-amp to scale teh
voltage to a convenient range seemed easier.

thanks Ian got that and the pdf I will get some in to play with

The aquatic hobby continues to gain in popularity, manufacturers are developing more and more professional equipment, each year. You need for your installation program will guide the depth and size of your tank, the light you need any special aquatic animals, if you intend to live plants in your design.

For fish only aquarium, with 3 watts of lighting per gallon of water in the tank. This amount will be the perfect light control algae - any strong, you may notice green algae begins to form. Remember to change the lights every 8 months to maintain a consistent light intensity.

One is to make your tank from the water evaporation. The second is to hold your fish tank metal halide lamp ballasts and feeding into your tank and three dust and other things. With a good marine fish tank, you have a tank hood, fish tank with your filters, heaters and aquarium fish lamp wires pre-cut hole equipment. When things get more and more like an aquarium lighting aquarium supplies, you have to get quality equipment.
