Query: Colder weather makes the darn thing beep

Bought one and eventually it kept beeping when weather would get colder (we live in south Texas). New batteries made no difference. Tried another and it lasted somewhat longer before doing the exact same thing. It is inside the house in a hallway, not outside. I don't understand why the temperature dropping outside would make it beep. ANNOYING and you end up having to take the battery out to stop it. I have cleaned both as directed and tried various batteries. Not a reliable product!!!
