Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

ZMOD4410AI2R Gas Sensor Module is designed for easy implementation to detect total volatile organic compounds (TVOC), estimate CO2, and monitor indoor air quality (IAQ). The module works reliably in various conditions, including very humid and dusty applications with the possibility of water spray, condensation, or immersion. The miniature 12-LGA assembly consists of a gas sense element and a CMOS signal conditioning IC.

Product Features

Sensor output based on AI machine learning algorithmic:

Absolute measurement of total organic compounds (TVOC) concentrations and indoor air quality (IAQ) to meet UBA air quality standard

Estimated carbon dioxide level (eCO2)

Absolute TVOC output to meet Public Building Air Quality (PBAQ) standards

Relative IAQ based on TVOC and odor changes

Algorithm to discriminate sulfur-based odors

High sensitivity to Hydrogen (H2) based on resistance output

Heater driver and regulation loop for constant resistance, minimizing effect of environmental temperature on signal

Built-in nonvolatile memory (NVM) for modulespecific data (configuration and calibration)

Ultra-low average power consumption down to 160µW

Excellent for low-voltage and ultra-low power battery applications

No external trimming components required

External reset pin (active-LOW)

Siloxane resistant

Supply voltage: 1.7V to 3.6V

Package: 12-LGA

• 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.
