  • Apparatus, method and system for surficial mold monitor based on weak electrical signals
    Patent number: 11795490
    Abstract: Disclosed are apparatus, method and system for monitoring mold based on weak electrical signals. The apparatus comprises a mold collector, a power supply, a trans-impedance amplifier, and an analog-to-digital converter, wherein the mold collector is smeared with a trophoplasm, and a substrate of the mold collector has electrical conductivity, the power supply is used for applying a voltage to the substrate of the mold collector, the trans-impedance amplifier is used for amplifying a weak current generated from the substrate of the mold collector to a voltage signal, and the analog-to-digital converter is used for converting the voltage signal amplified by the trans-impedance amplifier into a digital signal for determining the quantity of molds.
