PURPOSE: A circuit for an insect-trapping unit is provided to prevent the decomposition of insects by drying the internal parts of the insects using a heater. CONSTITUTION: A negative temperature coefficient element(130) is arranged around a heater(120). A switching element(140) is electrically connected with the high current path of the heater. A voltage comparator(150) includes a reference voltage terminal, a comparison voltage terminal, and an output terminal. A reference voltage is inputted in the reference voltage terminal. The comparison voltage terminal is electrically connected to the negative temperature coefficient element. An output terminal is electrically connected with the switching element. The voltage comparator maintains the temperature of the heater. |
