Post: In our marina I've build simple weather station based on RPi Zero. On every fifteen minutes the station is posting on twitter current weather conditions and water level with water temperature. The water level sensor was build as a set of thirty reed switch and resistor network in cooper pipe. Around the pipe there is 3D printed floating buoy with strong neodymium magnets. The voltage from sensor is measured with using the smart DS2438 chip. It also provide measurement of water temperature as well. The sensor is connected to the RPi zero with 15m cable (1-Wire). Whole system was working perfectly for one month then sensor died. I'm not sure, but I suppose, that culprit was the quite violent storm with lot of lightening. Now I installed the 1 Wire Pi Zero card and new sensor with similar ESD protection on the DS2438 end (DS9503 on OW, resistor-transil on power line, suppressing capacitors). Before I'll put the sensor into the water I have some questions: What are advantagee of using 1 Wire Pi Zero module instead of default RPi 1-Wire build-in solution? Can I expect that my new version of sensor can survive longer than previous? Do you have some recommendation how to protect 1-Wire sensors in such harsh environment - I mean ESD, inducted spikes etc...? Sorry for so long post ;-) Best regards Slawek
