Thank you for the code! It works and output i present below is exactly copy-paste from it!

Now it's much easier to get probes.

**Here's the easy-to-read Google Doc version https://docs.google.com/document/d/121ZH3omAZsdhFi3GSB-YdnasMjIQSGIcaS7QW6KsACA/edit?usp=sharing of what I already manage to get to know about the sensor.**

I already see the channel bits (000-1, 001-2, 010-3).I have to wire up antenna to the reciever so I get all the signals (I had to get the transmitter close to arduino to get all readings one by one).

Those with "???" are not-quite-sure about temperature values, all other ones are written from LCD. Those with "(no force)" came from transmitter as it was sending data WITHOUT me pushing the button.

I see some pattern, but can't decode it successfully yet.

What are those 'leading' zeroes?

Few more - next to each other and forced-nonforced readings from CH2.

Here are the CH1-2-3 differencies. The temperature changed slightly but it's possible to see where it happened in binary code.

and also other one - better to see:

I also tried to change battery to older one (to see the battery indicator) and I'm afraid I cant understand anything now...

Look at the pulse difference:

Another update.

Sensor and application has been on for hour or so, I didn't write down values.

These are the one printed - it looks like every column changes.

The last value is around 22.3*C 29%.
