I work in a biomedical laboratory that performs small animal surgeries on mice and rats. We face the problem of controlling the body temperature while the rat is being operated on. We could buy a expensive solution that costs 3K, or build something similar from scratch.
The temperature of the rat is controlled with a heat lamp. Temperatures are taken with a simple thermometer. The thermometer has a alarm that goes off if the temperature is too high or too low.
I want to build a circuit that automatically shuts off the lamp/dims the light. The lamp will be controlled by using the wires to the speaker to signal the light to turn off or on. (Simple board with a few transistors?)
I am stuck on how to make the small voltage from the speaker control the AC lamp. Any thoughts?
