The Apollo Automation PLT-1 is an ESP32-C3-based  indoor plant multisensor that measures soil moisture (capacitive), air temperature, humidity, LUX, and UV, which can be used with Home Assistant via ESPHome!

It also features an onboard piezo buzzer and addressable RGB LED. Soil temperature can be measured using the optional temperature probe add-on. The sensor comes in a battery or non-battery version, with the non-battery (USB-C powered, 5V 1A) version being significantly smaller - select an option before adding to your cart.

The PLT-1 uses a capacitive soil moisture sensor, which offers much better accuracy and durability compared to resistive sensors. Additionally, the ground contact portion is protected with a conformal coating, ensuring longevity and resistance to environmental factors.

Both versions of the PLT-1 come with a 3D printed case.

Note: The PLT-1B (battery version) does not include a battery or charger. You will need to source their own rechargeable 18650 batteries for the battery version, and a charger. Battery life is estimated at 6 months based on a quality rechargeable 18650 and the default sleep / wake settings.

Features

  • ESP32-C3-Mini based: ESPHome compatible, allowing plant monitoring in HomeAssistant
  • Capacitive Soil Moisture Sensor with conformal coating: Accurate and durable, perfect for monitoring plant hydration
  • AHT20-F Air Temperature & Humidity Sensor: Dust-protected for reliable air condition tracking
  • LTR390 UV & LUX Sensor: Measures light and UV exposure, ensuring optimal lighting for plants
  • RGB LED: Customizable for notifications (e.g., watering alerts, light levels)
  • Piezo Buzzer: Provides audible alerts for important plant care events
  • Battery and Non-Battery Versions: Flexible power options to suit different setups and needs
  • Home Assistant Integration: Easily automate and monitor plant health through your smart home system
  • Can be used with an optional DS18B20 Waterproof Soil Temperature Probe: Monitors soil temperature with precision

    Use Cases

    • Automated Watering: With its capacitive soil moisture sensor, you can set up automations to water plants only when moisture levels drop below a certain threshold.
    • Optimising Sunlight Exposure: Use the LUX and UV sensors to monitor light levels, ensuring your plants get the right amount of sunlight. Automate window shades or grow lights based on current light conditions.
    • Temperature & Humidity Management: Track air temperature and humidity with the AHT20-F sensor, adjusting indoor climate controls (like fans, heaters, or humidifiers) to maintain ideal growing conditions.
    • Soil Temperature Monitoring: Use the optional waterproof soil temperature probe to monitor and control soil warmth for temperature-sensitive plants, especially in colder months.
    • Visual & Audio Alerts: The RGB LED can be programmed for visual notifications, such as turning red when soil is dry or green when conditions are optimal. The piezo buzzer can alert you if immediate action is needed.

    A great casual shoe option with a touch of class
    Size: 9, Color: Navy
    The Amazon Essentials Men's Oxford Brogue Knit Dress Sneaker is the perfect "hybrid" shoe for anyone needing to bridge the gap between office formality and weekend comfort. It provides a sharp, polished look without the stiff, heavy feel of a traditional dress shoe. Why it’s a great choice: Athletic Comfort: Features a molded foam insole that provides cushioned support, making it comfortable enough for all-day wear and long commutes. Breathable Design: The soft knit upper allows for excellent airflow, keeping your feet cool even during busy days. Featherlight Build: These sneakers are built with a lightweight, flexible sole that reduces foot fatigue compared to standard leather oxfords. Versatile Style: The sophisticated brogue pattern and contrast trim pair perfectly with everything from tailored slacks to casual jeans.

    fit and comfort
    Size: 8.5, Color: Grey, Size: 8.5, Color: Grey
    Perfect fit, i was a little anxious about the size and fit. As you can see in the pictures, they look great and they are very light. I would give them a five-star rating as the comfort is there, only the point is a little hard on the toes, I hope that goes away with usage.

    Comfortable Oxford style shoes
    Size: 10, Color: Black, Size: 10, Color: Black
    Comfortable shoes that almost slip on each time. The material is a cotton mesh that is very soft and breathes well. I would not recommend walking in wet grass as the water can get through the mesh and make your feet wet. I normally wear size 10 for sneakers and this was true to size. I have extra room in the toe box. I do think the shoe feels a little narrow, but with the mesh area being stretchy, it does not cause any discomfort. The narrowness of the shoe makes it look more form fitting around my feet. Overall the shoe is comfortable while also giving an impression of high quality foot wear. It looks elegant too. The shoes also seem pretty durable given how much they feel like sneakers. The leather at the tip of the shoe does not scuff easily, which is great! Overall good value too!

    Poor quality. Returned after arrival, soles seem to be made of plastic.

    High End Style Without the Markup
    Size: 12, Color: Navy, Size: 12, Color: Navy
    I love the deep navy color of these shoes because it looks even richer in person than it does in the online photos. I usually wear a size 12 and these do have some extra room so could have gone down a half size. The white sole creates a nice contrast that makes the navy color pop. For me, these hit that perfect sweet spot where I look put together at work that is business casual without feeling like I am wearing stiff or formal dress shoes. These are comfortable shoes because the fabric is breathable and keeps my feet cool throughout the day. I especially like that the toe box bends naturally and does not leave ugly permanent creases across the top of the shoe. The padding around the ankle is soft and there is no rubbing even when I am walking a lot. My favorite part has to be the slight stretch around the opening because it lets me kick them off or slide them on without having to touch the laces. This is a total win for my lazy side and makes them my go to pair when I am headed out the door in a hurry. The stitching feels very durable and the overall build quality seems like it will hold up for a long time.
