Abstract
A simple and inexpensive water temperature sensor that may be mounted on existing water faucets or showers to provide a ready visible indication of the temperature of the water flowing through the faucet or shower. The temperature sensor comprises an outer transparent tube mounted coaxially with the pipe leading to the faucet or shower head, a number of O-rings mounted within the tube and spaced along the length of the tube to form different compartments along the sensor, and a number of differently colored tubular members respectively forming a second wall for the compartments, with each compartment being filled with a material, such as paraffin wax, with the material in each compartment melting at a different temperature from the material in the other compartments, to become transparent and reveal the corresponding colored inner tubular member, when the water flowing to the faucet or shower has a particular temperature.
