Embodiment Construction
[0008] 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 an analog-to-digital converter. The digital signal is then processed by the single-chip microcomputer AT89S8252, and then the measured value of sewage activity is displayed on the display. The specific structure of the bioactive 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, resistor R2 is connected to lead 1 of optical receiver S1, and connected to the output terminal at the same time OUT; one end of resistor R1 is connected to +12V, the other end is connected to electrolytic capacitor C1 and pin 1 of light emitting device F1, electrolytic capacitor C1, pin 2 of light emitting device and lead 2 of receiving device S1 are all connected to the reference potential ; The light-emitting de...
