At this time, it's only an project draft. I want to list all founded tips & articles about this topic

Description

The idea behind, use Heat elements(up to 200°) and control them via a ESP8266. This little guy will read the temperature and control via SSD(25A) the heater a kind off this graph. In short a PID Controller for Solder Reflow process...

Reflow Controller via BT

Solder Paste 140°

Solder paste 180°

Parts and Tools:

• Heat elements
• Solder paste 180°
• Solder Paste 140°
• NodeMcu
• PT100 Temperature Sensor
• Power Supply 12V/10A
• MAX6675 Type K Thermocouple Temperature Sensor Module

Code

Set a JSON Server and get and set the temperature. Get temperature via PT100 Sensor on a Analog pin, exists only on the new modules: http://www.instructables.com/id/ESP8266-ADC-Analog-Sensors/

The set methode, will power up the SSD via Digital Pin (on/off) and measure the temperature with [http://www.ebay.com/itm/131609531921](this module). Hold ths temperature until to next "set" command.

Chilipeppr will poll every 10 seconds via get and care about the graph.
