Read this official Leafony page and explain its key points in English. For hardware help, first ask for a photo or the installed leaf models, assembly and power sources, then the goal and tools. Clarify which LED or display changed and whether a cable or leaf was replaced. Do not equate an unseen reset button with an absent one, or I2C acknowledgement with a working display. Verify specifications against sources; distinguish observations from hypotheses. Follow a redirect to its destination; if unreadable, ask for the relevant text instead of guessing.

Description / headings (excerpt): Explore temperature, humidity, light, acceleration, and pressure sensing with AI01 and AI05. Distinguish discontinued AI02/AI03 leaves and optional sensors. / Discontinued leaves

On this page

Choose a sensor leaf according to what you want to measure, such as temperature, humidity, light, acceleration, or pressure.

Leaf	Standard capabilities
AI01 4-Sensors	Temperature, humidity, light, and acceleration
AI05 Env Sensors	Temperature, humidity, and pressure (BME280), plus acceleration (LIS2DW12)

AI05 also has locations for optional SHT40, SGP40, and BME680 components. These are not fitted as standard, so gas or air-quality measurements need a configuration that includes the additional components.

Discontinued leaves

AI02 and AI03 are discontinued. The following information is for people who already own these leaves.

Leaf	Standard capabilities
AI02 SP&PIR (discontinued)	Infrared sensing for detecting a person approaching; also includes a speaker
AI03 MIC&VR&LED (discontinued)	Microphone input; also includes a potentiometer and LED

Approach detection depends on installation and detection range; sound measurements also depend on microphone sensitivity and processing. The microphone example is a starting point for exploring changes in sound. Using it as a calibrated sound-level meter requires consideration of accuracy and calibration as well.

For a new project that needs approach detection or microphone input, or for other measurements, you can also connect an external sensor. Your measurement target, range, frequency, and required accuracy will help narrow down the options.
