SKU_BOS0006_Boson_Steam_Sensor

Introduction

This steam sensor measures water amount on its petal-shaped pad and converts to analog output. The difference between a steam sensor and air humidity sensor is that the former is designed for detecting water droplets while the latter is for measuring water vapor content in air.
When water droplets falls on the detection area, the humidity goes up, and then the voltage increases. Besides the raindrops, water from frog and steam can also be detected. The steam sensor can be used with Arduino or micro:bit to make interactive projects for enviroment monitoring, such as simple rain gauges, steam level switch, etc.

Note: This product is not 100% waterproof, please do not immerse the 3P cable interface in water.

Usage Description

The sensor can sense the humidity in environment. Using with Arduino or micro:bit to make rain monitoring device.

The more water on the detection area, the larger the output signal, and vice versa.

Note: This product is not fully waterproof, please do not immerse the 3P cable interface in water.

Principle

The output voltage increases when the humidity of the sensor detection surface goes up.

Application

1. Rain Alarm

Description: Put the steam sensor outdoors, when there is raindrops on the petal-shaped detection surface, the buzzer will buzz to tell people that it is raining.

Components:


BOS0006 Steam sensor	BOS0020 Buzzer module	BOS0035 Mainboard-3IO

MBT0039 micro:bit	BOS0040 micro:bit BOSON Expansion Board

Tip: micro:bit and its expansion board will be used in programming projects.

3. Simple Flood Warning System

Description: Make a simple flood warning system. The system does nothing when the steam sensor detects that it is not raining; when the steam sensor detects light rain, the green LED lights up and the buzzer make sounds to alarm for 5 seconds; when the steam sensor detects moderate rain, the blue LED switches on and the alarm sounds last for 10 seconds; when the steam sensor detects heavy rain, the red LED turns on and the buzzer makes sounds for one minute.
