While there's no way to be sure-sure ... you can get into your
local LAN segment and send ICMP(/whatever) requests to the
correct L3 address with the wrong L2 address and see if you
get a response; this will show you if hosts/devices are listening 
promiscuously (which makes for a good starting point).

How can i know if there a sniffer running in my network?

If the hacker has had physical access to your network, even for just a
few minutes, then there are many ways he can install a sniffer you can
never find short of tearing everything apart.

If you care about your data, you better encrypt end to end.
