Remote Temperature and Humidity Monitoring

I've been experimenting with a remote internet based temperature and humidity monitoring system. This is currently in a remote 'home' about 1,800 miles from where we are.  I may also use it to monitor the Roadtrek when it is "stored"via a Verizon jetpack.

I'll post more info including manufacturer's data after I'm satisfied with the performance and reliability. After a month, looks good so far.

The system consists of battery powered sensors with wi-fi connectivity and a wi-fi/internet gateway. For this to work one must have a good internet connection. The data is pushed into the "cloud" and can be accessed with an android or apple smart phone, from virtually anywhere.

The reliability seems good. That's one of my concerns. But after a month there have been no data disruptions. The sensor does work from within an operating refrigerator. However, colder temperatures reduce battery life. One of the uncertainties is sensor battery life, which is reputedly a year or more under normal "ambient" conditions. Battery life is reduced under colder conditions. I would like to get 5-6 months.

I'm currently monitoring the kitchen temperature, the refrigerator internal temperature, and the temperature of a heated storage room which is about 60 feet from the wi-fi gateway.  The amount of data per sensor is about 20 days. That's fine for me.

The system includes smartphone alerts for settable alarms. For example, I've set the refrigerator temperature alerts at higher than 46F. I don't care about the "low" temperature and so I did not set a "low temperature" alert.

I'll publish more data after a few months and I would like to determine the battery life before posting again. Here are a few photos of the smartphone screen:

White Sands Missile Base and Museum

After leaving Roswell we continued to the White Sands National Monument. Then we continued 30 miles west on US 70 to White Sands Missile Base.

Entry requires a quick background check and a photograph. This took about 10 minutes. We had decided to park the Roadtrek in a parking area outside the base and then we walked the short distance to the security office. The museum is only a few yards from the entry so we walked that, too.

The displays are really interesting. A scale model of the first nuclear device, all sorts of rocketry, a really interesting full scale cut-away of a V2 rocket and even some drones, including a Soviet are Hind helicopter drone. It was well worth the stop. At the end of the post is a link to a larger photo collection.

Roswell NM -Alien Encounter

What a difference two weeks makes! In 2015 we attempted to stop in Roswell NM but a sudden winter storm created a temperature drop of about 50F during the day. That storm with icy snow in North Texas delayed us several hours, too late to see the sights of Roswell.

This year the weather was cooperative and so we stopped at Roswell about noon and walked the downtown area. We were able to visit the UFO Museum. The museum was fascinating, with the expected extraterrestrial exhibits and a definitive chronological display of the great Roswell UFO "coverup." There are also fascinating exhibits of crop circles and ancient alien lore, as well as some movie related exhibits. We enjoyed it.

Headed Southwest to escape the winter

It's time to leave the north and head south for the winter. Not quite endless summer, but it is to be an infrequent winter. This year we left earlier than usual and the weather was wonderful. This allowed us to stop in Roswell, NM, the Sand Dunes National Monument and the White Sand Missile Base. The total distance was 1837 miles.
Here was the length of each day.  This included travel, sight-seeing and meal time:

• Day 1, 1:15pm-9:30pm, 471 miles 
• Day 2, 9:00am-5:30pm, 460 miles
• Day 3, 8:00am-5:30pm, 416 miles.
• Day 4, 8:30am-5:45pm, 342 miles
• Day 5, 8:00am-10:30am, 148 miles

Here's a data table for 6 days. The first was local miles with average speed 15 MPH. The actual trek was over 5 days. Mileage (MPG) at 55-65 MPH is about 15. Speed limits were generally 70 - 75 MPH. We travel at the speed limits. Our average speed including local miles over the 5 days was 64 MPH.
