摘要

The revised circuit is similar to the previous version in that a 47-Ù resistor is used to heat a 150-Ù thermistor (see the figure). A resistor divider network formed by the thermistor and a 100-Ù resistor monitors the ambient temperature. When air blows over the thermistor, it cools the thermistor, increasing the voltage at the junction (the node labeled Temp). The voltage at this junction is monitored continuously by the MCU's ADC channel0.
