Liquids

Features
1. A humiture sensor module to test temperature and humidity, which uses the sensor DHT11.
2. Humidity measurement range: 20 - 90%RH.
3. Temperature measurement range: 0 - 60℃.
4. Output digital signals indicating temperature and humidity.
5. Working voltage:DC 5V; PCB size: 2.0 x 2.0 cm.

This sensor sits in line with your water line and contains a pinwheel sensor to measure how much liquid has moved through it. There's an integrated magnetic hall effect sensor that outputs an electrical pulse with every revolution. The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.

Introduction
When wired with a 5v supply, the power light will be on. When the sensor detects no raindrop, D0 is high and the indicator keeps out. Drop some water onto the sensor. The more drops, the lower value at A0. When the value of A0 is smaller than the value set, D0 will change from high to low and the indicator will light up.

Application
It is widely used in the automatic wiper system, smart lighting system and sunroof system of automobiles.

Detailed Description :

Water Sensor water level sensor is an easy-to-use, cost-effective high level/drop recognition sensor, which is obtained by having a series of parallel wires exposed traces measured droplets/water volume in order to determine the water level. Easy to complete water to analog signal conversion and output analog values can be directly read Arduino development board to achieve the level alarm effect.
