The Technological Federal University of Paraná in southern Brazil has a pre-incubatory program for startups and our group has passed all the phases of the selection process so far (as of 08-dec-19) at the Campo Mourão campus.

The RF module can be changed to better suit the environment. The nrf24l01 can have a short range depending on the environment. Since the amount of data sent and received by each device is not so high to require gigahertz frequency modules. A LoRa module using 915Mhz bandwidth can increase its range.

The price per unit for the sensor devices can get lower if the production method changes from prototype to commercial product. A board with an Arduino can be more expensive than a board with all the components on that single board.

We have noticed the possibilities in the choices available regarding gas sensor modules and we have noticed that it is possible to use different modules for different applications. Greenhouse gases are mostly harmful to humans so monitoring more gases for health purposes is an idea...
