基于STM32F103控制的八通道比色检测技术OA

Based on the colorimetric principle combined with multi-channel parallel detection technology,an efficient detection system has been developed.This instrument can understand the growth situation of microorganisms by measuring the turbidity of the sample.It in-tegrates the functions of temperature control and shaking culture,accelerates the rapid response of microorganisms,and can test the growth situation of microorganisms in 96-well plates.To achieve online monitoring and cultivation of various microorganisms,the core of this instrument is to determine the growth status of microorganisms by receiving the intensity of the signal from the photodiode.The light source is realized through one-fiber-eight-optical-fiber to achieve independent detection of 8 sample channels.Then,the analog sig-nal is converted into a digital signal by the analog-to-digital conversion chip(ADC)and sent to the main control.At the same time,the main control chip controls the motor,heating plate,fan and other loads.It has the functions of solution mixing and temperature con-trol.It ensures the detection accuracy and significantly improves the detection efficiency.
