The scenario
TEC temperature control for photonics using a Raspberry Pi running a PID algorithm to maintain stable optical device temperature.
What is in this drawing
Read the decisions behind it.
01
H-bridge driver for bidirectional TEC current (heating/cooling)
02
NTC thermistor as temperature sensor
03
External ADC (MCP3008) to overcome Raspberry Pi's lack of analog input
04
SPI communication between RPi and ADC for fast sampling
Precision thermal management in laser systems, optical tables, and any photonic setup requiring sub‑mK stability.
