The compact wind speed sensor uses semiconductor technology to achieve a compact size and high-speed response that is easy to mount into equipment.
It is used SEMITEC’s unique mechanism to measure wind including dust and moisture.
In addition, it can be used in various applications by changing the attachment.
・Mounted in dryers, vacuum cleaners, air conditioners, drones, etc.
・Visualization of energy saving and preventive maintenance by air flow management in piping
・Air conditioning and dust control in houses, buildings, factories, data centers, etc.
・Air circulation and intake and exhaust control in labs, clean rooms, etc.
・Detection of clogged intake and exhaust filters, visualization of replacement and maintenance timing
・Application to security devices, VR devices, etc.
・Detection of exhalation strength
We will propose suitable attachment (product) shapes for each application.
