[0027] The solar cell 203-1 of the solar processor 203 is a 0.7mm thick amorphous silicon thin film battery with 8 inline cells and an open circuit voltage of 4.2V. A circuit is made on the back of the solar cell 203-1 and is bound with an energy management chip 203-2, a temperature and humidity display chip 202-3, a microprocessor (MCU) 203-4, a charging plug 203-5, a temperature and humidity switch 203-6 and electronic components 203-7, forming an energy collection module, a boost circuit module and a temperature and humidity display module.
