Description
The PLT-1B does not include a battery or charger due to shipping constraints. Users will need to source their own 18650 for the battery version. Battery life is estimated at 6 months based on a quality 18650 and the default sleep / wake settings.
Use Cases
The combination of soil moisture, soil temperature, UV, and air temperature/humidity sensors allows you to care for every aspect of your plant’s health. The Flower Card above can be paired with Open Plant Book to find your plant and automatically apply its ideal conditions.

I've found that the moisture tracking is very accurate, and the sensor also measures other vital stats for plant health - amount of sunlight, humidity, soil temp, etc. What's more, it's very customizable and you can have it on 24/7 with wired power, or battery operated and set to wake at user-defined intervals.
