After a trial period, I have to say that I can not understand Martins statement. The sensor in the air stream of Vetilators is, is achieved a motor voltage of about 5.1 volts with an airflow temperature of just 24 ° C. If the sensor is not in the draft increases the voltage to approximately 6.8 volts. Holding the NTC between your fingers, you can reach a voltage of 8.2 volts. With the hair dryer from a distance blown, I do not want the part so burn, the temperature continues to rise. Summary: It Works! Four stars because I like to have function: When falling below an adjustable minimum temperature a disconnection of the fan takes place. On exceeding of the value is started with a small (for example, 4V) voltage, which is then to approximately input voltage increases with the temperature. That this would not be the case, I was due to the photos already clear.
