The quest for the perfect USB battery, part 4

The last time we broached the subject, we found a USB battery from WaveShare that could power experiments based on Yoctopuce modules with quite respectable performance: 19 days of continuous use. But we're not giving up just yet. This week, we're turning our attention to products from Voltaic Systems: if the specifications published on their website are anything to go by, there's a good chance that their USB batteries work exactly the way we want them to.

Emulating an SDI-12 sensor

When we designed the Yocto-SDI12, we intended it to collect data from SDI-12 sensors, either by interrogating them explicitly, or by monitoring the activity of an existing recorder. So this module was not originally intended to behave like an SDI-12 sensor. But acting upon a request by a customer, we have now added this new capability to the Yocto-SDI12.
