The constant temperature hot wire sensor is used to monitor and calculate the heat loss of the main hot wire resistor of liquid water. The temperature sensor is used to monitor and feedback the evaporation temperature of the airborne cloud water and the current air temperature. The evaporation latent heat of the current airborne cloud water is calculated by the evaporation temperature of the airborne cloud water. The thermistor is used to monitor and calculate the liquid water hot wire resistor and the mixed water hot wire resistor and calculate the heat loss of the liquid water hot wire resistor and the mixed water hot wire resistor respectively by the liquid water hot wire resistor and the mixed water hot wire resistor. The sampling area of ​​the liquid water main hot wire resistor and the mixed water main hot wire resistor are monitored, fed back, and recorded by the area sensor. Hot wire measurement is a PWM drive method, which reduces the pressure of heat dissipation and thus achieves miniaturization. At the same time, the dynamic range will be sacrificed compared to the linear drive solution. The fundamental reason is that the switching speed limits the minimum duty cycle that PWM can reach. The voltage on the hot-wire resistor can be calculated through amplifier A1 and the subsequent filter and AD conversion. The current flowing through the hot-wire resistor can be calculated through amplifier A2 and the subsequent filter and AD conversion. Then the hot-wire resistance value and power value can be calculated. The PID controller is responsible for achieving constant temperature control of the hot-wire resistor.
