The probe of Digital Temperature and Humidity Sensor LFH50 is mainly composed of a temperature-sensitive resistor and a humidity-sensitive capacitor. The resistance value of the temperature-sensitive resistor is proportional to the temperature. The capacitance value of the humidity-sensitive capacitor is related to the surrounding humidity. The higher the humidity, the lower the capacitance value. The core components of the digital temperature humidity sensor LFH10 are the silicon chip and the control circuit. The control circuit will read the changes in resistance and capacitance and the silicon chip will generate 0-5V or RS485 signals. The advantage of the temperature and humidity sensor LFH10 is not consumed power and can still provide real-time and accurate temperature and humidity monitoring even when the power is off.
