When rain is detected it will generate a interrupt that we handle in the sketch.
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.
Introduction in this instructable we construct a rain gauge with arduino and calibrate it to report daily and hourly rainfall.
This sketch will create two devices on your vera controller.
The rain collector i am using is a re purposed rain gauge of the tipping bucket type.
Arduino rain gauge calibration.
We use this increment the bucket count and the amount of rain that has fallen.
As far as the arduino is concerned the rain sensor appears as a switch.
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 tipping bucket rain gauge is the key external input that allows the system to do its job.
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.
The statechangedetection example sketch in the arduino editor was adapted to register a bucket tip.
Tipping bucket rain gauges use a funnel to direct water onto a see saw of two side by side buckets.
This is a tipping bucket rain gauge based on rain gauges that are used by professional meteorologists.
In my gauge 100 ml of water slowly poured.
Rainfall mm rain gauge collection area cm2 x volume of water cm3 or ml needed to tip the bucket x 10.
When rain is detected the input is pulled to ground before returning to 5v.
Pump up your weather station with a tipping bucket rain gauge an rf transmitter and receiver a picaxe microcontroller and an lcd.
It came from a damaged personal we.
