Wind Sensors

[ddelorme]

The ESP32 uses more power as some of the power saving stuff is still in development and I have not read enough to solve the issue with losing Wifi during sleep. In my testing via wifi I have not found issue with lag at 10 hz. There is lag to OPENCPN but SignalK has no issues. I have had issues getting the analog part right as my chip does not have the ref voltage fuse burned but I am getting it closer.. I feed the unit via a buck converter as it operates as the base for my anchor light. The Davis not that expensive.. compared to a cheaper unit that breaks or is generally flaky. The Davis runs fine at 3.3V even with the long factory wire.
The Esp32 has a more usable ADC. 12bit and several pins . Some are not useful with Wifi. I might add 1 more Mosfet to control my Motoring light as well. I was under the Impression ultrasonic sensors used a fare bit of power as it has elements so when it is cold or the wind is blowing they work harder. I wonder how they deal with spider webs. A little friction is not bad in the direction as the mast has some vibration to it.

Calypso claims LOL ya they seem to stretch the truth a bit and operating at 10hz is much different then as a home weather station taking a reading every 30 sec or so.
Well time to relax now it is close to -37 C right now as I am about 100km south of the Hudson bay.
