From the project
Collection of electronic circuits I designed, tested, and documented using KiCad
A beginner-friendly automatic sanitizer pump controller using an IR sensor module input, TIP32C transistor switching stage, and DC pump connection.
This project demonstrates a simple sensor-controlled pump switch. The schematic provides an IR sensor module input at J3, a TIP32C transistor switching stage, and a DC pump connection at J2.
When the sensor module input changes state, the transistor stage responds and controls the pump connection. Verified prototype behavior is documented separately under Verified Prototype Observations.
