Measurements from the real world often contain noise. Loosely speaking, noise is just the part of the signal you didn’t want. Maybe it comes from electrical noise: the random variations you see when calling analogRead on a sensor that should be stable. Noise also arises from real effects on the sensor. Vibration from the engine […]

There are two things that you don’t want to do with any rechargeable battery on a routine basis: Overcharge it. Overdischarge it. While the above are true for lead-acid batteries, they are particularly true of Lithium-Ion chemistries, but for different reasons. With Lead-acid batteries: Lead-acid batteries – particularly the “flooded cell” types (e.g. those to

The power saving mode here is what sets this Instructable apart from other examples showing day of the week, month, day of the month, time, humidity, and temperature. It is this capability that allows this project to be run from a battery, without the requirement for a “wall wart”. I had posted an earlier Instructable,

This project takes hourly temperature and humidity readings from a humidor. A Web API sends the readings to Azure SQL and Twitter. Story I WiFi enable something that that non-geeks would say “why did you do that?” I added a MRK1000 to a humidor. Every hour it sends temperature and humidity reading. Now according geek laws, if
