Tipping Bucket Rain Gauge Arduino Code

Conversion of bucket tip events to mm of rain is can be done in a spreadsheet or in code.

Tipping bucket rain gauge arduino code.

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. My problem is that blynk only catches the pulse randomly even though i have a timer set to fire every 10 ms. Assembling the rain gauge.

Arduino rain gauge calibration. The statechangedetection example sketch in the arduino editor was adapted to register a bucket tip. This is a tipping bucket rain gauge based on rain gauges that are used by professional meteorologists. This value will be needed in the arduino sketch.

When rain is detected the input is pulled to ground before returning to 5v. I think raising the screw will increase the amount needed to tip the bucket. 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.

Rainfall mm rain gauge collection area cm2 x volume of water cm3 or ml needed to tip the bucket x 10. Set interval to read rain gauge void rain int. We use this increment the bucket count and the amount of rain that has fallen. The other a sensor that.

In my gauge 100 ml of water slowly poured. I have a tipping bucket rain gauge similar to that pictured that sends a pulse to esp8266 every time the bucket fills and seesaws past the reed switch. Anyway they should be about the same the amount is not critical but i set mine for 5 ml. The screw on the left actually affects the bucket on the right and vice versa.

As far as the arduino is concerned the rain sensor appears as a switch. This is the part of the code that controls it. It came from a damaged personal we. The rain collector i am using is a re purposed rain gauge of the tipping bucket type.
