======================================
EPE Magazine May 2002

A simple design to monitor the temperature of freezers, giving
an audio warning  of low temperature caused by e.g. leaving
the door open.

based on the PIC 12C508, extremely easy to build, using
only five components. Battery powered.

Parts are available from the usual component sources. Please note
that EPE does not provide kits but many of the requirements can
be met by our advertisers.

The latest version of the software is available from
