Atmel Mega88 Temperatur meter, Type K sensor, Heat set and regulator
This project is made together with MRJ (OZ2ELA)
Design goal: to make a good accurate temperature meter, with data logging output using serial port 19200 Baud 8N1
To be used to heat regulate all sorts of heaters/boilers and so on
Heater power on/off output 5V level, can drive external LED input mains relay to handle large scale owens
Display temperature using sensor type K, read out temperature and set on 6 digit LED display from 0 to 1000C
Resolution 1C, accuracy 1C
Celcius / Farenheit readout selectable
PCB layout large
PCB layout small
Here is the board with all components mounted.
