IOT Sensor node HW and SW test program

Hello freelancers,

Its needed to design a sensor node that its used to get the weight(as a bathroom weight scale up to 200kg and a resolution of 50 grams), temperature/pressure/humidity and location then transmit the data via the Lora module.

This HW shall run on battery, so overall its requires a low power consumption.

The transmission range shall be up to 10KM(~6 miles).

To complete the project its required to deliver HW(schematic, Gerber files and two prototypes) and a minimal SW that test the functionality.

For more details we can use the chat.

Please put the right price for the project despite the estimated range.

The time its our allay! -> you will have plenty of time to make it, of course a thigh time plan shall be even better.

Quality its a must! -> the HW design must be as good as it can be and a previews experience with LORA, GPS, load cells and low power uC its needed.

Late edit:

All the bidder shall receive a mini-task, in consist in a doc file with two points:

-to make an estimation

-and to make a proposal
