Overview
Tiny plant sensor is an open-source printed circuit board by sini6a, from the sini6a/tiny-plant-sensor repository on GitHub. It is a 2-layer board of 30.5 × 125 mm with 6 parts on 8 nets, routed with 29 tracks and 1 via.
It is built around the ATTINY85-20PU. Its parts include 1 capacitor, 1 resistor, 1 IC, 1 diode and 1 connector. It belongs with the sensors and measurement and power boards and the AVR (ATmega, ATtiny) boards of this library.
Main components

README.mdTiny Plant Sensor 🌱
The Tiny Plant Sensor 🌱 is a low-power sensor designed around the Attiny85 microcontroller and powered by a CR2032 coin cell battery. This sensor is designed to monitor the moisture level of a plant and provide a visual indication when watering is required.
Features
- Utilizes Attiny85 microcontroller
- Powered by CR2032 coin cell battery
- Monitors plant moisture using capacitance level
- Sleeps and wakes up every 6 seconds for power efficiency
- Blinking LED indicates the need for watering
Operation
The sensor operates by periodically waking up to check the plant's capacitance level, determining if watering is necessary. If the plant requires watering, the sensor activates a blinking LED every second. Otherwise, it remains in a low-power state.
Usage
Simply deploy the Tiny Plant Sensor in the vicinity of the plant you wish to monitor. Ensure the CR2032 battery is properly inserted, and the sensor will autonomously manage its sleep-wake cycles to conserve power while providing visual cues for watering needs.
Feel free to customize and adapt the Tiny Plant Sensor for your specific plant monitoring requirements.

Questions
How big is the Tiny plant sensor PCB?
It measures 30.5 × 125 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tiny plant sensor use?
6 parts, built around the ATTINY85-20PU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Tiny plant sensor KiCad files?
From the sini6a/tiny-plant-sensor repository on GitHub, at the commit this page was made from: the board is tiny-plant-sensor.kicad_pcb and its schematic tiny-plant-sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tiny plant sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask sini6a before reusing the design.
