The mcu (atmega328p) measures the thermistor and it's internal voltage and sends the data with the nRF24L01 to one connected to a raspberry pi. Then it goes to sleep for 54sec. The raspberry pi stores the data in a file and runs a python script. The python script plots the data using gnuplot, and adds text to the image containing the newst measurment. The finished image is shared with http.
