Serenity Lake Communications is a research and development company focusing on cellular communications for low data usage devices. The initial project was a solar charge controller monitor. That monitor has operated for many years providing hourly reports on status. Reports from the test charge controller have been made for 15 years with low cost data service.

For temperatures that do not go below -20 C except on rare occasions, there are commercial solutions now available. The ReadyEdge offering from Morningstar Corporation is in testing as the company develops the product into the final configuration. For the last three years, monitoring equipment from Victron Energy has been used in an operational environment. Further development of a custom solution has been suspended; however, the product is available.

Serenity Lake Communications has been using special low usage LTE / 4G data services for solar power monitoring, cameras and other devices at remote locations. Solar power monitoring uses extremely low amounts of data where a plan offering 10 years of service for under $20.00 is suitable. Cameras in use have a data use under 1 megabyte per day standby. In typical security use at a low activity site, the total usage averages less than 50 megabytes per month. Low data usage plans for cameras typically cost less than $20.00 per year.

Currently developing a fully capable suite of applications using cellular modules and low data service plans to enable custom programming beyond the capabilities of commercial systems. Developed solutions range from hobby type systems based on Arduino and Raspberry Pi computers to fully developed Linux based Single Board Computers with low temperature tolerance, low power usage and high reliability.

See the other areas of this web site for details. A large number of surplus items are available which are functional; however, no longer needed for future development. A small stock of solar powered 4G/LTE Pan-Tilt-Zoom cameras is available. These cameras can take advantage of low cost data services or be used with other commercial data providers for higher usage.
