Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The OPT4001YMNR is a light/number sensor (single-chip illuminance meter) for measuring the intensity of visible light. The spectral response of the sensor is highly matched to the visual response of the human eye. A specially designed filter on the device removes the near-infrared component of common light sources in order to measure accurate light intensity.The output of the OPT4001YMNR is semi-logarithmic, with 9 binary logarithmic full-scale light ranges, each with a highly linear response, giving the PicoStar™ model a measurement capability of 312.5µlux to 83klux and the SOT- 5X3 model a measurement capability of 312.5µlux to 83klux, while the SOT- 5X3 model has a measurement capability of 5.5µlux to 83klux. This feature allows the photosensors to have a 28-bit effective dynamic range. The built-in automatic full-scale range selection logic eliminates the need for the user to select the appropriate gain setting based on illumination level.

• 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.
