Description

The PLT-1 is a indoor plant multisensor that measures soil moisture, air temperature, humidity, LUX, and UV. 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 (B) and non-battery version, with the non-battery version being significantly smaller. The battery version is delayed by a month.

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.

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.

Details

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).

A great, data-centric plant health monitor

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.
