Transmit/Receive analog signals

Click For Summary
The discussion focuses on building a system to wirelessly transmit and receive voltage readings from a resistance thermometer over a distance of about 5 meters. Participants suggest exploring commercially available wireless thermometer products as a simpler alternative to building a system from scratch. Recommendations include searching for components online, particularly for receivers, and considering infrared (IR) transmission for reliability in clear line-of-sight conditions. The project is deemed feasible for someone with basic electronic assembly skills, provided they can find suitable designs or components. Overall, adapting existing products may be the most efficient approach for beginners.

I'm completely new to transmitting/receiving signals, but I wanted to get a scope of what kind of components are out there that I could use to build this system.

I wanted to read the voltage drop across a resistance thermometer (Vt) and send this signal wirelessly to another circuit, where I could then read Vt on the receiving end. The distance between the transmitter/receiver would be ~5meters, so not too far.

Can someone recommend some components that may be easy to use for this purpose?
Is this project simple or do you think its something a beginner wouldn't be able to achieve?

Any input is much appreciated!

Thank You.

A search, https://www.google.com/search?source=hp&q=wireless+thermometer turns up many results of commercially available ones. If you can adapt one of those, it would be much cheaper (and easier) than building it from scratch.

To expand the search to wider temperatures, partially type in the search term and look at the suggested search options.

I take it that this is your real question.

If you can do electronic assembly (know which end of a solder iron to pick up :wink:), you could build one, of course you would have to find an appropriate design or design it yourself.

This is perfect, I had no idea these things existed!
I'll look into some receivers!
Thanks!
 
BTW, if you can be sure of a clear line-of-sight, you might consider using an IR Tx/Rx pair. You will still need to search for available modules, but IR can be more reliable that RF, depending on what sources of RF interference (or competition in the case of WiFi) there are.

Many/most of the consumer ones include both the transmitter and receiver with a visible digital display. If you need an electrical output, it might, or might not, be easiest to decode the drive to the digital display.
