light sensor circuit using pic16c63

Posted on Feb 7, 2014

This light sensor circuit that is photos sensor is the gap between light and electronics. This circuit is built by op amp and microcontroller PIC16C63 for control the sensor. This circuit is not precision application, but they can be effectively used in position photo sensing applications minus the headaches of amplifier stability. This is the fig

ure of the circuit. When the two, six or eight channel PGA is used in this system, the other channels can be used for other sensors or an array of photo sensors without an increase in signal conditioning hardware or PIC micro ® microcontroller I/O pin consumption. The multiplexer and high-speed conversion response of the PGA / Analog-to-Digital (A/D) conversion allows the photo sensor input signal to be sampled and quickly converted to the digital domain. Switching from channel to channel is then easier with the Serial Peripheral Interface (SPI) from the PIC16C63 microcontroller to the PGA. The PGA can be configured with a photo sensor in two different settings. These circuits are appropriate for signal responses from DC to ~100 KHz.
