 +Instead of the NiMH battery, a lithium battery will be used, since the NiMH type is not able to deliver enough current at cold temperatures.  
 If the solar panel delivers enough power, we can increase the data transmission frequency. If the thermometer is in a rather dark area, we reduce the frequency to save power.  If the solar panel delivers enough power, we can increase the data transmission frequency.
