![]() The Tipping BucketĪs shown in the photo below, the tipping bucket doesn't look much like an ordinary bucket. ![]() Now we can move on to the mechanical and construction details. The RF transmitter and a 9-volt battery are inside the case, and the antenna is the grey wire that exits from the bottom. 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. ![]()
