Finger-Clip Heart Rate Monitor
Phototransistor sensor with an analog filtering and amplification chain feeding an ADC and LCD.
Built a finger-clip optical sensor circuit using a phototransistor with analog signal conditioning (filtering and amplification stages) feeding an ADC for digital processing. Interpreted a provided schematic to construct, test and validate the full signal chain from sensor to LCD output.
Highlights
- Constructed the full analog signal chain from a provided schematic
- Validated each filtering and gain stage on the bench before integration
