Chapter 8: Field Worth Water Sensor/ H2O Stage Detector

Arduino and Processing sketch for use with a hardened water sensor for field deployments. The use of PVC to elevate the sensor above ground also helps you determine when a certain stage has been triggered.

Chapter 9: Using an Arduino with a Tipping Bucket Rain Gauge

Demonstrates how to integrate an Arduino with a tipping bucket rain gauge to include a remedy for filtering out noise in the reed switch. In this example, I use an Adafruit ProTrinket, but this can be done with any variant of an Arduino (i.e. Arduino UNO)
