Tipping Bucket Rain Gauge Arduino

The tipping bucket rain gauge is the key external input that allows the system to do its job.

Tipping bucket rain gauge arduino.

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. 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. Pump up your weather station with a tipping bucket rain gauge an rf transmitter and receiver a picaxe microcontroller and an lcd. The rain collector i am using is a re purposed rain gauge of the tipping bucket type.

Rainfall mm rain gauge collection area cm2 x volume of water cm3 or ml needed to tip the bucket x 10. Tipping bucket rain gauges use a funnel to direct water onto a see saw of two side by side buckets. As far as the arduino is concerned the rain sensor appears as a switch. It came from a damaged personal we.

In my gauge 100 ml of water slowly poured. Arduino rain gauge calibration. The statechangedetection example sketch in the arduino editor was adapted to register a bucket tip. When rain is detected it will generate a interrupt that we handle in the sketch.

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. 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. This is a tipping bucket rain gauge based on rain gauges that are used by professional meteorologists. Tipping bucket rain gauges use a funnel to direct water onto a see saw of two side by side buckets.

Introduction in this instructable we construct a rain gauge with arduino and calibrate it to report daily and hourly rainfall. We use this increment the bucket count and the amount of rain that has fallen.
