Here is the draft for the DHT22 temp/humidity sensor board. This sensor was the original purpose for building this device. Next most important sensor to me is K-type thermocouple, as I want to make a toaster reflow oven.
Setup: A requirement of this project is having the ability to reflow surface mount components on a PCB. I chose to go with the ControLeo2 Reflow Oven Controller. I ordered the full kit from their website Whizoo. I decided to use the exact same toaster...
I first added my newly burned ATMEGA328 and programmed it. Then I added the pressure sensor.The pressure sensor has solder pads under the chip! yikes! I used solder paste and a toaster oven.I needed to reflow the solder because the first time the BMP180...
Hackers have been modifying toaster ovens to act as reflow ovens for years. Nate Seidle himself from Sparkfun describes one example at: https://www.sparkfun.com/tutorials/60 . Sparkfun also developed a (now discontinued) controller PCB designed to make...
