An inexpensive temperature-humidity sensor for a server room?

Question

Iron

Good afternoon, can anyone advise an inexpensive temperature-humidity sensor, from the necessary:
​​- work via ethernet
- snmp statistics and snmp traps
- temperature and humidity sensors
I had experience with such a MessPC Ethernetbox 2, but the price is ~ 400EUR for everything, but it's like something expensive, maybe someone knows analogues, but cheaper.
Thank you.
P.S. no time to collect on raspberry pi

Answer 1

buy a sensor for a computer, and already from it pull ready-made cheap ones with your parameters, I didn’t find them via snmp
