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

Water Coffee Flow Sensor Switch 0.3-6L/min YF-S401 white G1/4


Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. This one is suitable to detect flow in water dispenser or coffee machine.

  • Compact, Easy to Install
  • High Sealing Performance
  • High Quality Hall Effect Sensor
  • RoHS Compliant

Dry reed pipe sensor module -magnetic control switch

A reed switch is a sensor that closes circuit in the presence of a magnetic field. Reed sensors can be used in many application where contact less On/Off is required. However reed switches can be fragile to use directly, hence this module can make it easier to handle and mount the sensor in various applications.
It gets operated by the applied magnetic field. When the device is exposed to a magnetic field, the two ferrous materials inside the switch pull together and the switch closes. When the magnetic field is removed, the reeds separate and the switch opens.

MQ-4 gas sensor sensitive material used in clean air conductivity is lower tin dioxide (SnO2). When the sensor is present in the environment in which the combustible gas, the sensor's conductivity increases with the concentration of combustible gases in air increases. Using a simple circuit can be converted to the change in conductivity of the gas concentration with the corresponding output signal. MQ-4 methane gas sensor for high sensitivity, propane, butane and has a good sensitivity. The sensor can detect a variety of flammable gases, especially natural gas, is a low-cost sensors for a variety of applications.

For home or factory methane gas, natural gas and other monitoring devices to test natural gas, methane 300 to 10000ppm;

Joystick Module Biaxial Buttons Rocker Sensor

This is a joystick very similar to the 'analog' joysticks on PlayStation 2 controllers. Directional movements are simply two potentiometers - one for each axis. Pots are ~10k each. This joystick also has a select button that is actuated when the joystick is pressed down. There are 5 pins on board: VCC, GND, X, Y and Button. Connect the module with 5V power suppy with VCC and GND, you can read out the joystick status by X,Y and button pins. When using the 5V power supply, the default analog output for X,Y is 2.5V. With the direction of the arrow, the voltage up to 5V, and the opposite direction down to 0V.
