Wind Sensor

This is a high-sensitivity micro wind speed sensor for detecting low wind speeds, applying SEMITEC’s proprietary temperature sensor technology, ultra-thin film thermistor (Patent No. 6842600), as the sensing element.


The wind cools the heating element.
If the temperature of this heating element can be measured precisely, it can be used as a low wind speed sensor.

part structure

・Thin-film thermistor FT connected to metal frame and film coated.
・Heat generating/thermosensing part is only 200µm thick.
・New ultra-high accurate temperature sensor and high sensitivity wind speed sensor.
(Output approx. 400mV at 1m/s)
