Embodiment Construction

[0008] It is composed of sewage biological activity sensor, amplifier, analog-to-digital converter, single-chip microcomputer AT89S8252, and display. The electrical signal output by the sewage biological activity sensor is sent to the amplifier. After being amplified by the amplifier, it is converted into a digital signal by the analog-to-digital converter. The microcontroller AT89S8252 performs data processing, and then the display shows the measured value of sewage activity. The specific structure of the sewage biological activity sensor is: +12V power supply is added to capacitor C2, potentiometer W1, and resistor R1; the other end of capacitor C2 is connected to the reference potential , the resistor R2 is connected to the lead 1 of the optical receiver S1, and connected to the output terminal OUT at the same time; one end of the resistor R1 is connected to +12V, and the other end is connected to the electrolytic capacitor C1 and the pin 1 of the light-emitting device F1, th...
