Tipping Bucket Rain Gauge Arduino

The statechangedetection example sketch in the arduino editor was adapted to register a bucket tip.

Tipping bucket rain gauge arduino.

It came from a damaged personal we. This is a tipping bucket rain gauge based on rain gauges that are used by professional meteorologists. When rain is detected it will generate a interrupt that we handle in the sketch. The buckets are sized so that a certain amount of water causes the see saw to tip usually 01 inches of precipitation collected by the funnel an 8.

Tipping bucket rain gauges use a funnel to direct water onto a see saw of two side by side buckets. Tipping bucket rain gauges use a funnel to direct water onto a see saw of two side by side buckets. The tipping bucket rain gauge is the key external input that allows the system to do its job. Arduino rain gauge calibration.

When rain is detected the input is pulled to ground before returning to 5v. This sketch will create two devices on your vera controller. The device works by funneling rain water onto a tipping bucket which resembles a teeter totter with each end having a bucket that hold approx 2 ml of rainwater when one side fills up the bucket tips and rainwater begins collecting in opposite bucket. The rain collector i am using is a re purposed rain gauge of the tipping bucket type.

Pump up your weather station with a tipping bucket rain gauge an rf transmitter and receiver a picaxe microcontroller and an lcd. The buckets are sized so that a certain amount of water causes the see saw to tip usually 01 inches of precipitation collected by the funnel an 8 inch diameter funnel collects about 8 2 ml of water per tip. This is the first article in a three part series that describes the construction of a tipping bucket rain gauge with a wireless connection to a picaxe controlled lcd liquid crystal display. As far as the arduino is concerned the rain sensor appears as a switch.

We use this increment the bucket count and the amount of rain that has fallen. Conversion of bucket tip events to mm of rain is can be done in a spreadsheet or in code.
