From the project
BivalveBit firmware
Based around a ATmega4808 microcontroller Designed to fit inside a nominal 3/4" schedule 40 PVC plumbing pipe (<18.5mm inside diameter) along with an 18650 size Lithium-Ion battery cell. Provides one I2C 4-pin port for communicating with a IR heart rate sensor Provides one analog 4-pin port for communicating with an analog sensor such as the A1395 Hall effect sensor (with SLEEP pin on the 4th wire). * Writes data to a standard microSD card
