Description
Claims (2)
- 시스템콘트롤러의 마이컴(1)와, 이 마이컴(1)으로부터 동작전압을 공급받아 시스템이 설치된 주변장소의 습도값을 측정하는 습도센서부(2)와 이 습도센서부(2)의 습도측정값에 따른 AC출력전압을 DC전압으로 정류시키는 정류부(3)와, 이 정류부(3)로부터 공급받은 습도측정값에 따른 DC전압과 써미스터(TH)를 통해 감지된 온도값에 따른 측정전압을 비교한 다음 일정습도에 대한 온도편차가 발생할 경우 이를 온도보상해 주는 편차보상부(4)로 구성된 것을 특징으로 하는 습도센서의 제어회로.
- 제 1 항에 있어서, 상기 편차보상부(4)는 그 반전단자가 저항(R2)을 통해 정류부의 출력단에 연결되고, 비반전단자는 저항(R3)을 통해서는 바이어스전압(+Vcc)에 연결되는 한편 병렬연결된 써미스터(TH) 및 캐패시터(C3)에 의해 접지되며, 저항(R4)을 통해 출력단이 반전단자에 연결된 연산증폭기(OP2)로 구성된 것을 특징으로 하는 습도센서의 제어회로.
