![]() ![]() The completed outdoor assembly is shown in the following photograph.Īs you can see, the collection device is a plastic funnel which channels the rainwater into a small section of aluminum downspout that houses the actual tipping bucket mechanism.Īs the bucket tips, electrical signals are routed through the green wires to the RF transmitter contained in a weatherproof plastic case. Part 3 describes the RF receiver that receives the signals and the PICAXE 08M2 microcontroller that interprets the signals and displays the rainfall data on the LCD. Part 2 describes the modification and use of an RF (radio frequency) transmitter that sends rainfall collection indications. Part 1 focuses on the mechanical construction of the tipping bucket mechanism. This is the first article in a three-part series that describes the construction of a "tipping bucket" rain gauge with a wireless connection to a PICAXE-controlled LCD (liquid crystal display.) Pump up your weather station with a tipping bucket rain gauge, an RF transmitter and receiver, a PICAXE microcontroller, and an LCD.
