I'm trying to understand the sensor boards... a) what kind of battery does it need? b) what's the range? c) what's the battery life like? d) what frequency range does it operate in and will stuff in my house interfere with it? e) can I buy extra sensors? I think you should consider answering these questions on the growguard site in order to facilitate even more sales. :)

Harwoodr, It uses a 9V battery that lasts for about 6 months. It uses 868MHz ISM band and does not interfere with anything in your house. Outside range is about 50 yard/meters, inside a couple of rooms.
