Oregon Scientific RGR202 Wireless Rain Gauge

Description from Amazon

You are going to love this little wonder. Beyond telling you the temperature, and alerting you to unsafe driving conditions, this handy gadget can help you ensure your wine collection is cool, your greenhouse is fecund, and any temperature-sensitive goods are safe and fresh. The face display is easy to read, thanks to its large LCD digits, making it visible from across a room. An included stand allows you to place it on a table or desk, or you can choose to use its integrated magnet to mount it to the refrigerator. One wireless remote is included, but you can use up to three remotes depending on how many locations you want to monitor.
