Lefoo Temperature and Humidity Transmitter with Display LFH50 The probe of Digital Temperature and Humidity Transmitter 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 LFH50 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 LFH50 is not consumed power and can still provide real-time and accurate temperature and humidity monitoring even when the power is off. Feature * Two outputs Temperature and Humidity * Anti-interference * CE and RoHS certificated Features of Temperature and Humidity Transmitter with Display LFH50 A variety of installation methods and output methods are optional The shell design is light and beautiful, with LCD backlight temperature and humidity dual display The power supply and output have over-voltage and reverse connection protection , with a high protection grade IP65 Adopt high-precision sensors and main control , with good long-term stability and anti-interference ability
