Rain Gauge - KNX The rain sensor demands a 12V DC power supply and a direct connection to the KNX bus. KNX telegrams are sent out through the Weinzierl kberry. https://www.weinzierl.de/index.php/de/alles-knx1/knx-module/knx-baos-modul-838 Rainfall is measured with a seesaw. Each time the seesaw is tilted, a reed switch is triggered by magnets at its end. The Raspberry calculates the number of pulses multiplied by the amount of water in the seesaw. In winter, a 12V DC heater is installed to measure rainfall. It is controlled by a PT100 and the Raspberry. Installed Components Magnet Neodymium 5 * 10mm https://www.amazon.com/Magnetastico%C2%AE-coupling-magnet-pinboard-magnet-whiteboardmagnet-cylindermagnet/dp/B075PF7W5Y/ref=sr_1_6?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=magnetic+5*10&qid=1567935260&s=gateway&sr=8-6 Reed Switch https://www.amazon.com/gp/product/B0782Z7PS3/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 Heater https://www.amazon.com/gp/product/B07FJXP5ZJ/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 PT100 https://www.amazon.com/gp/product/B074NT36ZC/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 Step Down Module https://www.amazon.com/gp/product/B07S5CSXKF/ref=ppx_yo_dt_b_asin_image_o00_s00?ie=UTF8&psc=1
