- I am not an electronics engineer but do play around with gadgets
-
- I have a temperature sensor from SEARS with LCD display. It gives
- the inside outside temperature.
-
- Q: The LCD display is large and I was trying to see if a
- small size one is available from the market and if anyone can
- suggest replacing methodology. I wouldn't mind a LED display,
- infact, would prefer it. I am trying to fit it in a small
- box in the dash board so it merges into the standard
- setting of the car.
-
- Can somebody suggest to a novice the method to replace
- this! The range is "0" to "130.9" F. So the display has
- the following LCD's
- _ _ _
- | |_| |_| |_|
- | |_| |_| . |_| F
- ^ ^
- | |----- is painted as a F
- |
- |
- |----------- is Painted as a DOT
-
- ?) Would I get incorrect results if I extend the wire
- another 10 ft as I need to hide it under the carpet too.
-
- ?) What would be the best place for the outside sensor
- to be placed at so as to get the best results - Ambient
- temperature. What is in the sensor? A temperature
- sensitive resistance? What kind is generally used? Can I
- buy it from Radio Shack? What is it called. Would
- placing 4 or 5 of them in series or paralled give better
- results. Which?
-
- thanks in advance
