Air quality sensors are important devices for monitoring pollutants such as PM2.5, PM10, VOCs, and CO₂ in the environment. They are widely used in homes, offices, industrial sites, and smart city systems. Sensor performance may decline due to dust, humidity, chemical contamination, or prolonged use. Therefore, regular maintenance is essential to ensure long-term stable operation and accurate data.

In modern electric tricycles, the DC contactor, as a crucial circuit component, plays an indispensable role. It not only controls the start and stop of the motor but also plays a key role in switching the battery current. Improper DC contactor wiring can not only affect the performance of the electric tricycle but can also cause battery damage, control system failures, and even threaten driving safety in serious cases. Therefore, ATO Automation will provide essential and correct wiring methods for every electric tricycle user and maintenance technician.
