Apollo PLT-1 Ultimate Plant Sensor

[lime sigil]

The PLT-1 is equipped with a capacitive soil moisture sensor, providing enhanced accuracy and durability over resistive alternatives. The sensor’s ground contact portion is coated with a conformal layer, ensuring long-lasting performance and resistance to environmental factors. It also features an AHT20-F air temperature and humidity sensor, which includes dust protection, an LTR390 UV sensor for Lux/UV measurements, an RGB LED, a piezo buzzer, and an optional DS18b20 waterproof soil temperature probe (20 cm / 7.8 inches). Like all of our sensors, the PLT-1 is Made For ESPHome, fully local and open-source! The PLT-1 uses wifi to connect to Home Assistant with no hub (besides home assistant), no cloud, and no internet required.

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 (https://github.com/Olen/lovelace-flower-card) can be paired with the Open Plant Book (https://github.com/Olen/home-assistant-openplantbook) to find your plant and automatically apply its ideal conditions.
Dimensions: 41x26x14 mm (77 mm stake into ground)

Oh boy, I’ve been waiting for this!!!

[pastel whale]

ooh nice! I have a bunch of small plant pots so a lot of the normal sized ones don't work for me. do you know what would be involved to make the stake even smaller? 🤏 does the precision drop off quickly, or stop working entirely?

[astral tiger]

I've not tested it but imagine it could go smaller, it would just need a different calibration for it. A lot of people have suggested a pro ( or some better name ) that would have like 1 hub connecting multiple smaller moisture sensors over wires. So then each plant didn't need the ESP chip and such. That type of a product might solve what you are talking about.

Nothing on our roadmap for it currently but our product development is pretty heavily community driven.

Yeah it's cool to have it all in one, but I'd actually prefer a hub or even just a tether for individual ones so the bulk can be tucked away

Also maybe avoids any accidental water splashes making it to the esp
