Anecdotally, it seems that when a low-level player places a Lure Module, it attracts first-stage Pokémon, but some times, we get Lure Modules that attract second-stage Pokémon.
Question
Does a player’s level dictate the evolutionary stage of Pokémon attracted by Lure Modules?
Answer
There is no evidence of trainer level affecting what gets spawned when a lure module is active. It looks like what gets spawned is pretty much just random and independent of the trainer that placed the module.
An interesting thing that I found, however, suggests that placing modules and using incense in relatively unpopulated areas can potentially result in rarer Pokemon spawns.
