Consumer electronics

Consumer electronics Pressure sensors and silicon microphones are widely used in the field of consumer electronics, with clear division of labor and complementary cooperation. Pressure sensors are primarily utilized for waterproof pressure detection and altimeter functions in smartphones (to assist GPS positioning), as well as for fit detection in TWS earbuds and smartwatches. Silicon microphones, on the other hand, focus on audio experience, not only enabling noise reduction for voice calls, active noise cancellation (ANC) for TWS earbuds, and voice interaction, but also being widely applied in smartphones/tablets, smartwatches/bracelets, and AR/VR devices.

Smart home appliances/Internet of Things In the broader field of the Internet of Things and smart homes, pressure sensors, flow sensors, and silicon microphone sensors play a pivotal role, enabling remote monitoring and intelligent control through wireless communication technology. At the device control and monitoring level: Pressure sensors are widely used in washing machines, water purifiers, and coffee machines for liquid level monitoring and precise water level control. At the same time, they are also combined with IoT wireless communication methods such as 4G/NB-IoT/LoRa to remotely monitor the water pressure status of fire hydrants, sprinkler systems, and gas networks, as well as the liquid level in low-lying areas such as drainage networks and river channels. Flow sensors are mainly used in air conditioning/fresh air systems, humidifiers, and refrigerators to precisely control wind speed, and often work in conjunction with temperature sensors to achieve constant temperature control. In addition, silicon microphone sensors mainly empower smart TVs/remote controls, smart speakers, and environmental control devices such as thermostats/lighting to enable voice interaction. At the system integration and application level: The aforementioned sensors and wireless communication technologies jointly support a series of intelligent applications, including smart gas meters, fresh air systems paired with wireless safety valves, etc., ensuring the safe and efficient operation of critical infrastructure such as water supply and gas supply.

Medical Electronics

Medical Electronics In the field of healthcare, flow sensors, pressure sensors, and silicon microphones jointly constitute key technical support, which are applied in multiple dimensions such as therapeutic devices, rehabilitation monitoring, and hearing assistance. Specifically, flow sensors are primarily used in ventilators and nebulizers, responsible for precisely regulating airflow and liquid medication delivery, ensuring the effectiveness and safety of treatment. Pressure sensors are focused on rehabilitation training and wearable health monitoring scenarios, assisting in motor recovery and continuously tracking vital signs through real-time sensing of pressure changes. Silicon microphones, with their high-sensitivity sound pickup characteristics, are widely used in hearing aids/assistive listening devices, telemedicine stethoscopes, and cochlear implants, playing a central role in enhancing sound collection, improving auditory quality, and achieving remote precise auscultation.

Industrial control In the fields of industrial automation and public utilities, pressure transmitters, flow sensors, and silicon microphones are responsible for monitoring key parameters, measuring media, and perceiving the environment, respectively. Pressure transmitters are primarily used in boilers, compressors, steam turbines, and pneumatic systems to ensure stable operation under high-pressure and high-temperature conditions. They are also widely deployed in mine ventilation systems for real-time monitoring of air pressure to ensure operational safety. Flow sensors focus on precise control and measurement of fluid media: they are used for protective gas injection in kilns in the industrial sector, and support flow monitoring and process control in water supply networks, wastewater treatment plants, and circulating water systems in municipal engineering. Silicon microphones, with their sound pickup capabilities, are primarily used in smart cameras and doorbells to achieve security monitoring and abnormal alarm functions.

Automotive Electronics

Automotive Electronics In the field of automotive electronics, the sensors independently developed by Haobang Gaoke work in concert to provide crucial support for vehicle handling safety, ride experience, and intelligent interaction. In terms of handling and safety, pressure sensors undertake core functions such as brake pressure monitoring, tire pressure monitoring, passenger recognition, and sitting posture monitoring, ensuring driving safety and occupant protection. Flow sensors are applied to hydrogen energy flow monitoring, serving new energy vehicles, and are also responsible for precise control of air conditioning wind speed inside the vehicle. In the intelligent cockpit, silicon microphone sensors, with their high signal-to-noise ratio and voice pickup capabilities, are widely used in in-vehicle voice assistants, active noise reduction systems, and identity recognition.

Oil and gas/power chemical industry In the field of oil and gas and industrial safety, pressure transmitters, flow sensors, and pressure sensors jointly constitute a comprehensive protection system from production and transportation to safety monitoring. Pressure transmitters are primarily deployed in long-distance pipelines for natural gas and oil, wellheads, and tank trucks. They are responsible for continuously monitoring pressure changes during transportation and storage, and can be applied to safety monitoring scenarios such as oil and gas leaks, promptly detecting abnormal pressure drops. Flow sensors focus on the metering and control of gaseous media, used for flow monitoring in inlet and outlet pipelines, trade settlement metering at gas stations, and assisting in leak monitoring through abnormal flow changes. Specialized pressure sensors further focus on the safety control of specific gases (such as VOCs, H₂S, SF6), monitoring pressure and flow throughout the entire process of storage, transportation, and use, and triggering alarms in the event of toxic and hazardous gas leaks.
