Update:
The protocol is as follows:
32 bit messages, repeated 6 times.
- 8 bits for id
- 4 flag bits. 1st bit is battery indicator.
- 12 bits for temperature. Temperature in float format xx.x * 10, truncated to int16.
- 8 bit checksum LFSR-based Toeplitz hash

You can determine the bit timing and protocol of the transmitter using the methods in this tutorial: Reverse Engineer Wireless Temperature / Humidity / Rain Sensors — Part 1 « RAYSHOBBY.NET
But without the transmitter, it is probably hopeless. The TX141V2 sensor is available on eBay.
