As a follow-up to the simple audio power meter described in [1], the author has developed a more sensitive version. In practice, you rarely use more than 1 watt of audio power in a normal living-room environment. The only time most people use more is at a party when they want to show how loud their stereo system is, in which case peaks of more than 10 W are not uncommon.

At the
heart of this heat-sensitive switch is IC LM35 (IC1), which is a linear
temperature sensor and linear temperature-to-voltage converter
circuit. The converter provides accurately linear and directly
proportional output signal in millivolts over the temperature range of
0�C to 155�C. It develops an output voltage of 10 mV per degree
centigrade change in the ambient temperature
