Tipping Bucket Rain Gauge Arduino

Tipping bucket rain gauges use a funnel to direct water onto a see saw of two side by side buckets.

Tipping bucket rain gauge arduino. Arduino rain gauge calibration. As far as the arduino is concerned the rain sensor appears as a switch. When rain is detected the input is pulled to ground before returning to 5v. Rainfall mm rain gauge collection area cm2 x volume of water cm3 or ml needed to tip the bucket x 10.

Pump up your weather station with a tipping bucket rain gauge an rf transmitter and receiver a picaxe microcontroller and an lcd. Tipping bucket rain gauges use a funnel to direct water onto a see saw of two side by side buckets. We use this increment the bucket count and the amount of rain that has fallen. 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.

In my gauge 100 ml of water slowly poured. The tipping bucket rain gauge is the key external input that allows the system to do its job. Conversion of bucket tip events to mm of rain is can be done in a spreadsheet or in code. Introduction in this instructable we construct a rain gauge with arduino and calibrate it to report daily and hourly rainfall.

It came from a damaged personal we. 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 sketch will create two devices on your vera controller. This is a tipping bucket rain gauge based on rain gauges that are used by professional meteorologists.

The rain collector i am using is a re purposed rain gauge of the tipping bucket type. The statechangedetection example sketch in the arduino editor was adapted to register a bucket tip.
