Project 10：Steam Sensor
(1)Project Introduction
This is a commonly used steam sensor. Its principle is to detect the amount
of water by bare printed parallel lines on the circuit board. The more the
water content is, the more wires will be connected. As the conductive
contact coverage increases, the output voltage will gradually rise. It can
detect water vapor in the air as well. The steam sensor can be used as a rain
water detector and level switch. When the humidity on the sensor surface
surges, the output voltage will increase.
The sensor is compatible with various microcontroller control boards, such
as Arduino series microcontrollers. When using it, connect the sensor to
the analog port of the Micro:bit microcontroller, and display the
corresponding analog value on the serial monitor.
Note: the connection part is not waterproof, therefore, don't immerse it in
