3 days ago Hi,
Of course you can also simply switch the sensor off and then on again when required. This also works well and is probably even best for your application. I mainly introduced the energy-saving mode in order to be prepared for a variant with a solar cell. The 16uA are not that critical there.

2 days ago Hey,
just out of curiosity, what are the benefits of keeping the sensor in standby vs turning it off completely between measurements? I mean we are "loosing energy in the form of a 16ua current" so there is probably an advantage of this method which justifies this energy consumption. I'm just asking to have all the details here to pick the right approach for me and I'm a little bit worried that I'm overlooking something.

Hi,
so I understand that since version 3.4 we have a standbymode with a current of 16u. I would like to understand why such a standby mode is necessary and we just can't turn off the sensor completely and just turn it on for a measurement? It would like to build a device which is powered by a CR2032 battery like the HHCC Soil Moisture Meter (Mi Flora Sensor), for that a standby current of 16u is already quite high considering also that the actual measurement, microcontroller and rf chip will also consume additional power.
Best regards
