Analog rain/steam sensor for Microbit – Elecfreaks Octopus

Elecfreaks Octopus – Analog Rain/Steam Sensor for Microbit
A simple and reliable module that responds to changes in humidity on the board: when humidity increases — for example, rain, steam, or increased humidity — the analog output voltage will increase. The sensor is suitable for easy connection to platforms such as Micro:bit and Octopus:bit, and can also act as a humidity-based touch sensor.

Key Features
Fast response and high sensitivity — Moisture on the sensor surface causes an increase in the output voltage.

Simple Plug-and-Play interface — 3-pin connection (Signal / VCC / GND) compatible with analog I/O, suitable for operation at 3V–5.5V.

Various and educational uses — Can be used to detect rain, steam, or even a touch sensor when moist surfaces touch the board.

Usage warning — Avoid getting the connections wet or connecting directly to water, as the connection is not durable.

Compact dimensions — approx. 30×20×6mm.
