cfastie "The Arduino snow depth gauge seems to produce good data. It is an ESP8266 and laser rangefinder I2C sensor ($9 total cost). As expected data collec..." | Read more » over 4 years ago
cfastie "The sunlight is not an issue. For a winter-long monitoring goal, a few measurements every day are plenty, and those can be taken at night. With the..." | Read more » over 4 years ago
cfastie "I tried one of those little six dollar laser rangefinders (vl53lox) for measuring distance to snow. Those rangefinders don't work at all in sunligh..." | Read more » over 4 years ago
cfastie "I think a laser rangefinder might work well for this. Put it on a pole and point it downward to measure the distance from the rangefinder to the sn..." | Read more » over 4 years ago
cfastie "I have not heard of anyone using a microcontroller (Arduino or ESP board) to read data from an SD card. But maybe it is possible. A more common str..." | Read more » over 4 years ago
