Measuring low water in streams accurately
To recap from a previous blog, a project looking at effects of drought conditions is monitoring the low water depths in-stream, with transducers that have a capability of reliably measuring changes of ±0.01’(feet) in low water conditions, connected via an open interface 4-20mA to an Onset U30 cellular wireless logger. For reliability, it was decided to use two water transducers per logger. Over ...[Read More]
Mayfly version 0.3 bugs
A few weeks ago we found that some of the version 0.3 Mayfly boards were assembled by the manufacturer with an incorrect voltage regulator on the section of the board that generates the switched 5-volt boosted supply. This error does not affect any other functionality or features on the Mayfly. The only issue is that you will see 3.3 volts on the “Sw_5v” pin instead of 5 volts. We hav...[Read More]
