This rain gauge measures rainfall using a self-emptying bucket-type mechanism. Each time enough rain is collected, it triggers a momentary button closure that can be read by your electronics project.

The switch closure can be measured with interrupt pins or a digital counter, making it suitable for microcontroller-based weather monitoring. The centre conductors of the RJ11 connector are connected to the gauge's switch.

This is the rain gauge used with the SparkFun weather meter kit.

Features:

  • Self-emptying bucket-type rain gauge
  • Activates a momentary button closure for each measured rainfall increment
  • Switch closure can be measured using interrupt pins
  • Switch closure can be measured using a digital counter
  • Centre conductors of the RJ11 connector are connected to the gauge's switch
  • Used with the weather meter kit

Specifications:

  • Rainfall per closure: 0.011" (0.2794mm)
  • Output: Momentary button closure
  • Connector: RJ11
