1 The Grove - Temperature Sensor uses a Thermistor to detect the ambient temperature. The resistance of a thermistor will increase when the ambient temperature decreases. It's this characteristic that we use to calculate the ambient temperature. The detectable range of this sensor is - 40 - 125ºC, and the accuracy is ±1.5ºC Grove - Temperature Sensor Thermistor: 온도에 따라 전기 저항치가 달라지는 반도체 회로 소자 오늘 배울 내용 1. 시리얼통신 2. 온도센서에서 Analog 신호 입력 (Input) 및 온도 계산 3. 온도에 따라 피에조 부저 출력 (Output, PWM) 피에조 부저는 +/- 방향성 없음.
