[PROJECT] How To Build a Source Point TEMP/UMIDITY

[Zio_f@solo]

Good Morning,

I'm new in this forum.

I need help to a project. So, i want to build a box with a temp/umidity sensor, a circuit to translate and send data coming from the sensor using a transmitter. All this components need to be powered with batteries.

This is a simple schema:



My question is: "How can i build the circuit?".

Thanks to all.

What range to you want from your transmitter to your receiver? Non license transmissions are only available for low power at a frequency of 433 MHZ, should give up to 200m range with decent aerials both ends.

UMIDITY is wrong spelling for humidity.

It is easy to build a circuit that was designed by somebody else. Print the parts list then simply gather the parts and solder them onto the pcb designed by somebody else.
You want a temperature/humidity radio transmitter but you forgot that you also need a receiver designed by somebody else, a pcb for it and a parts list for it.

Is this a school project and you must demonstrate that you learned how to solder?

if you have a local wireless connection to the internet your transmitter could be something along the lines of the Microchip RN171

it has simple UART and SPI interfaces and would enable to to connect to remote TCP or UDP servers
