PURPOSE: A complex detection circuit for temperature and humidity is provided to complexly detect temperature and humidity through the single circuit, thereby facilitating measurement and application to equipment requiring temperature and humidity information. CONSTITUTION: A complex detection circuit for temperature and humidity comprises a moisture-sensor part(10), a filter part(20), a control signal combiner(50), an amplifier(60), a control signal generator(70), a temperature sensor part(80), and a power supply part(90). The filter part converts the voltage level of a humidity sensor signal input from the humidity sensor part. The control signal combiner synthesizes the humidity sensor signal with an offset setting signal inputted from the control signal generating part.
