Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The OPT4001DNPRQ1 is an optical digital sensor (single-chip illuminance meter) for measuring the intensity of visible light. In order to accurately measure light intensity, a filter has been specifically designed on the device to closely match the photosensitive response of the human eye and to filter out the near infrared component of common light sources.The output of the OPT4001DNPRQ1 is semi-logarithmic with 9 binary logarithmic full scale optical ranges, with a highly linear response within each range, and can measure over a range of 400 µlux to 107 klux. This capability gives the photosensor a 28-bit effective dynamic range. Built-in auto-range selection logic dynamically adjusts the device gain setting to the light level, providing optimum resolution under all conditions without the need for user input.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
