1. Environment data from Station1
>> HW I2C connection to SDA/SCL pin of RaspberryPi
>> python libiary smbus(I2C) to get data from sensors
>> upload per reading to cloud by socket
>> python libiary Flask to setup the server
>> Sensors - SPS30, SCD30, SHT30 and xxx30
2. Environment data from Station2
>> use Eva kit Kita for HW connection
>> python kita libiary to get data from sensors
>> upload per reading to cloud by socket
>> python libiary Flask to setup the server
3. Environment data from Station3
>> directly connect sensors to STM32 discovery board for HW connection
>> C code to drive the sensor and use the TCP protocol to send the data to cloud
>> python libiary Flask to setup the server
