Wireless Rain Gauge
- container that catches rain and measures the amount of rainfall.
- A device for collecting and measuring the amount of rain that falls
- A rain gauge (also known as a udometer or a pluviometer [Pluviograph ] or an ombrometer or a cup) is a type of instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation (solid precipitation is measured by a snow gauge) over a set period of time.
- gauge consisting of an instrument to measure the quantity of precipitation
- having no wires; "a wireless security system"
- Lacking or not requiring wires
- transmission by radio waves
- radio: medium for communication
Reverse engineering the rain gauge
This is an Oregon Scientific wireless
rain gauge. I have a Propeller microcontroller logging the packets via a UHF radio receiver (off camera). Every time it receives a packet, a servo tilts the rain gauge to increment the gauge's counter.
The alligator clips supply external power, so that the rain gauge's battery voltage sensor reports a constant value.

rain gauge, Christmas present, last year (or year prior??!)
Pretty cool concept: rain collects in fixed capacity teeter-totter collector, passes fixed magnet over sensor to increment by 1.
Neither rain nor temp gauge were realtime- collector and display units seem to sync at some slower interval.
