Sensors are generally composed of four parts: sensitive components, conversion components, conversion circuits, and auxiliary power supplies. In the information age of today\'s society, sensors have played an important role in various fields, as they are an important means of obtaining information in the fields of nature and production. According to their purpose, sensors can usually be divided into pressure sensors, position sensors, energy consumption sensors, thermal sensors, etc. But if sensors want to be sold in the EU market, they need to apply for CE certification and attach CE labels.

The remote control car is a model car that can be remotely controlled by a 2.4GHz radio remote controller. Generally can be divided into: toys, car models (R/C), police and so on. According to the appearance of the car body, it can be divided into: RV (flat sports car), off-road car, cart, pull cart, container truck and so on. Remote-controlled cars have many scientific uses, including dangerous environment, working in deep sea and space exploration. But in general, this kind of wireless products need SRRC certification if they want to be put on the domestic market.

On April 14, 2023, the American National Standards Institute (ANSI) and the Standards Council of Canada (SCC) released ANSI/CAN/UL 2743:2023, a safety standard for mobile energy storage. This new edition is an important revision of UL 2743:2018 and UL 2743:2020 and includes a series of standard optimizations.

Recently, the California Office of Administrative Law (OAL) officially approved the abolition of portable lighting types from the Title20 Home Appliances Regulations, effective April 25, 2023.

In order to ensure the quality and safety of the mobile power supply, the mobile power supply before entering the market needs to be tested and certified by an authoritative third-party inspection and certification body. Applicable standards for mobile power supply include: GB 4943.1, GB 31241, GB/T 35590 and so on; Among them, GB 4943.1-2022 and GB 31241-2022 will be adopted for CCC certification of mobile power supply.

On April 21st, 2023, California Environmental Health Hazard Assessment Office (OEHHA) added 1,1,1- trichloroethane (CAS registration number 71-55-6) and leucomalachite green (CAS registration number 129-73-7) to the list of hazardous substances in California, because of carcinogenicity.

Energy storage power refers to the storage of electric energy, and the usual mobile phone charging treasure can also be regarded as a kind of energy storage power, but generally the energy storage power refers to the power supply with high battery capacity and high charging and discharging current. Energy storage power supply has the characteristics of light weight, large capacity, high power, long service life and strong stability. It can output common power interfaces such as DC and AC, and can also supply power for notebook computers, drones, photographic lights, projectors, rice cookers, electric fans, kettles and other equipment. However, in general, such products need to be certified by FCC if they want to export into the American market.
