I now live in a house with an electric water heater that warms the temperature on the fly to the temperature we set on the display, provided it’s not too cold. But in the past, I lived in colder climates with water pre-heated in a hot water tank, and accessible from most taps in the house. Each time I took a shower I had to adjust the cold and hot water taps, wait a bit and do further adjustments to get the right temperature, not too cold, not too hot.
I’ve just come across a little gadget that you ease this process as it displays the water temperature on an LCD display. The installation looks fairly easy, and there’s no need for batteries as it’s self-powered with the flow of water. Some of the key features of the device include:
- Display – 360-degrees rotatable & waterproof LED display design: and waterproof design for better viewing
- Sensor – High-precision temperature sensor with 0 to 100°C range, 0.5°C accuracy
- Power – No batteries required: the device harvests its energy from the water flow
- Dimensions – 8.10 x 8.06 x 3.00 cm; screw nut size: 1/2 inch
- Weight – 160 grams
- Materials: ABS, PC
None of the sites I’ve checked clearly mention how energy harvesting works here, but I assume water may make a small wheel turn to generate enough electricity to display the temperature on the LCD.
