Currently it looks the cheapest option to buy 3 kitchen 0.1c accurate LED thermometers (for the price of 1 thermocouple resistor WTF!) and modify them. I will get one and see if whats in there - a pic and a small cct board I guess - if I can get the pic out without damaging it I can dump the code and see how it works and may be able to extract the temperature info one way or another. Calibration is a strange one - what does one calibrate against freezing and boiling are rarely where you think they should be!-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On 09/11/12 09:54, tom wrote:Someone recently mentioned the http://www.raspberrypi.org/archives/2129 brewery controller. The temperature sensors are +/- 0.5 C which isn’t accurate enough for my liking. Does anyone know of better ones?Could you not use a more accurate thermometer to calibrate each sensor? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://www.enigmail.net/ iEYEARECAAYFAlCdMLUACgkQsoRLMhsZpFdOaQCgjbqUB3K7O0aFmtjgcEJtsdlG 2YEAn3hffBkZp1fjsLiHtS/dPIyQI86e =pY+q -----END PGP SIGNATURE-----
