Mayer, if the CR1220 battery powering the internal clock is low on voltage this could be causing a time mismatch and no connection during the cellular connection sequence.
Thanks for asking. The team at LimnoTech is working on a new hierarchical system for organizations that will allow for different levels of editing rights for multiple individuals. This will allow individuals other than the site owner/creator to manage the site. As I understand it, the target is to release this update by the end of the year. As for…[Read more]
I am putting together a micromet station that includes some sdi12 sensors (meter group Terros 21, and Acclima 315H) and some analog thermistors (homebuilt but the same components as the Campbell Sci 107) with a second resistor (24.9K) wired between the return wire and the ground. I have some separate pieces of example code for the SDI12…[Read more]
I seem to be having some problems with a Mayfly ver 0.5b data logger. It has not recorded data since October 29th, nor has it connected to the cellular network since that day. I believe it is the cellular card on the board, but wanted to inquire about functionality because I cannot find documentation on the meaning of the LED indicators. When the…[Read more]

Gosh complex – it was great in the above all the linkages – reviews technically to my mind are features, and synergy in using them. Seems to me reviews can be on how to use (introducing to a new audience), tea […]
@khaase interesting getting the LiSOCL2 activated.
My 2Cents is it would be good to characterize the 350mA pulse – and isolate it from the mega1284’s high impedance LiSOCL2. That could mean that for the “high impedance” (for a battery) LiSOCL2, the current draw has to be kept below a threshold, treated as a constant current source.…[Read more]
For electronics hardware – most people are used to shopping and then buying – simple transaction – however Open-Source Hardware at the board level can be different.
So, I’m interested in a discussion of how can OSH is used – Mayfly and other.…[Read more]
