– Functionality
> Completed
> In Progress
– User Interface
Circuit – Design
> Implemented current-to-voltage converter to detect
the photocurrent produced when photodiode receive
scattered light.
> The circuit was designed to have the photodiode
operate in photoconductive mode.
> The voltage produced from converting the current to
voltage is around 24mV. In order for the voltage to
be more detectable, an amplification is required.
> Active high-pass filter with non-inverting amplifier
with a gain of 47 was implemented.
Circuit – Phase I
> Combining the current-to-voltage converter and
active high-pass filter
Circuit – Phase II
> The output of the circuit will be connected to an
Arduino where voltage will be recorded into micro
SD card, and real time data will be sent via Bluetooth
Circuit – Arduino coding
> BTconnection.ino
> sdcard.ino
> All done & tested, partly shown.
