Ultrasonic sensors are widely used in many industries due to their advantages such as non-contact measurement, high precision, and strong anti-interference ability. The following are the main benefiting industries:
1. Manufacturing / Industrial Automation
- Material Position Detection
Liquid Level Monitoring (Tank/Trough)
Parts Identification and Sorting
2. Automotive industry
Parking radar/obstacle detection
Automatic parking system
Distance perception in driver assistance system
3. Logistics and warehousing
Cargo location detection
Automatic sorting line object counting
Robot obstacle avoidance and path planning
4. Packaging industry
Product length/height detection
Label positioning
Automatic packaging line control
5. Agriculture / agricultural machinery
Liquid level detection in grain silos / water tanks
Automatic irrigation water level control
Agricultural machinery navigation and obstacle avoidance
6. Medical equipment
Liquid level detection for liquid medicine bottles
Mobile device anti-collision reminder
7. Building automation / smart home
Elevator door anti-pinch detection
Safety distance monitoring
Smart lighting or security system triggering
8. Environmental protection and water treatment industry
Sewage level monitoring
Liquid storage tank level warning system
Almost all industries that require non-contact distance measurement, liquid level monitoring or obstacle detection can benefit from ultrasonic sensors, especially in highly automated and intelligent scenarios.
