Soil Humidity Sensor Module

This is a simple moisture sensor can be used to detect soil moisture, when the soil water, the sensor output of the analog value will be reduced, and vice versa will increase. Use this sensor to make an automatic watering device. When you are not at home or after a long time, it can sense if your plant is already thirsty. To prevent the plants withered to know that is caused by water. With the Arduino controller to make your plant more comfortable, the garden is more intelligent.

   The sensor surface is metallized to extend its use of time. Insert it into the soil and then use the AD converter to read it. With its help, the plant will remind you: I want to drink water, please give me a little water to drink.

GP2Y1010AU0F Optical Dust Sensor including wire,resistor and capcitor

GP2Y1010AU0F is an optical air quality sensor, designed to sense dust particles. An infrared emitting diode and a phototransistor are diagonally arranged into this device, to allow it to detect the reflected light of dust in air. It is especially effective in detecting very fine particles like cigarette smoke, and is commonly used in air purifier systems.

The sensor has a very low current consumption (20mA max, 11mA typical), and can be powered with up to 7VDC. The output of the sensor is an analog voltage proportional to the measured dust density, with a sensitivity of 0.5V/0.1mg/m3.

To interface with the sensor you need to connect to its 6-pin, 1.5mm pitch connector
