Maker: Rocket Scream

Controls soldering reflow ovens or other temperature-controlled systems using a PID loop.

Provides an accurate thermocouple sensor interface using a MAX31855KASA+ for real time temperature acquisition. Controls an external Solid State Relay (SSR) (rated accordingly to your oven) and interfaces with an external K-type thermocouple.

Compatible with the PID library for Arduino.

Features:

  • 8x2 LCD with white characters and blue back light.
  • Two push buttons (breakout pins available for panel mount) connected to a single analog pin.
  • Red LED (breakout pins available for panel mount).
  • Screw terminals for thermocouple.
  • Screw terminals for SSR to control heating element/oven.
  • Buzzer with transistor for loud sound output.
  • Reset button.
