Dear Ruben, I think the rareness of hash function implementations in sensor networks may be because common sensors do not have a large amount of data needed to apply hash algorithms. Integrity and authentication are usually ensured by block cipher modes (e.g., CCM and CBC-MAC).
If you really need some hash functions, you can try some open source codes (in openssl). Or you can take advantage of the in-chip AES encryption to implement your own hash function (using Davis-Meyer construction, etc).
