Hello My outdoor sensor that transmit to a receiver at my home finally die on me. It is a Thermo.Hygro 433MHz Cable Free. That is what's on the front of it a picture is below. I want to replace it with another one But i thought maybe i could make this into a project using parts i have around here. I do have what frequency it uses by looking up the FCC ID Which is Here. What you see on the image is packing tape because i lost the clip to it that mounted on the side of my place :( .
So i need help on this project which should i do in order to make one? I do have a 433mhz transmitters and receivers i got form ebay would it work i do not know they are standard cheap transmitters and receivers. They can be found Here.
I do have a dht22 temperature and humidity sensor i can use. Also make it portable and able to save battery i been working on in my other project i can use on this one.
But there are a few things i been worried or wondering about. First is the frequency going to match up with the receiver that i have i don't know If it will know the Dht22 or the transmitter i have. So a lot of unknowns is why I need the help.
