Grove sensors - open source, environmental (lilybui)

  1. Dust sensor ($15.95) USD


    Used to create Digital (Lo Pulse) output to Particulate Matters (PM). Lo Pulse Occupancy time (LPO time) is in proportion to PM concentration. The output is for PM whose size is around 1 micro meter or larger. We can use the sensor to detect the dust indoors and outdoors.


  • Features:

    • Grove compatible interface(extra wire with connecter)
    • Supply voltage range: 5V
    • Minimum detect particle: 1um
    • PWM output
    • Dimensions: 59(W)x45(H)x22(D) [mm]

2. Air quality sensor 

This sensor is designed for comprehensive monitor over indoor air condition. It's responsive to a wide scope of harmful gases, as carbon monixide, alcohol, acetone, thinner, formaldehyde and so on. Due to the measuring mechanism, this sensor can not output specific data to describe target gases' concentrations quantitatively. But it's still competent enough to be used in applications that require only qualitative results, like auto refresher sprayers and auto air cycling systems. This sensor does better in providing qualitative results over a wide scope of target gases. In this demo, we define 4 statuses for reference in the .cpp file. They are:


  • Features

    • Responsive to a wide scope of target gases
    • Cost efficient
    • Durable
    Cautions

    • Require relatively clean air as an initial condition. 
    • Long time exposure to highly polluted air can significantly weaken its sensitivity.

3. Sound sensor ($4.90 USD)

The Sound sensor module is a simple microphone. Based on the power amplifier LM386 and the electret microphone, it can be used to detect the sound strength of the environment. The value of output can be adjusted by the potentiometer.

Features

 

  • Grove compatible interface
  • Wide supply voltage range: 4V-12V
  • Low quiescent current drain: 4mA
  • 2.0cm x 2.0cm twig module
  • Minimum external parts

4. Digital Light Sensor ($9.90 USD)

This module is based on the I2C light-to-digital converter TSL2561 to transform light intensity to a digital signal. Different from traditional analog light sensor, as Grove – Light Sensor, this digital module features a selectable light spectrum range due to its dual light sensitive diodes: infrared and full spectrum. You can switch between three detection modes to take your readings. They are infrared mode, full spectrum and human visible mode. When running under the human visible mode, this sensor will give you readings just close to your eye feelings.

Features:
  • Selectable detection modes
  • high resolution 16-Bit digital output at 400 kHz I2C Fast-Mode
  • Wide dynamic range: 0.1 – 40,000 LUX
  • Wide operating temperature range: -40°C to 85°C
  • Programmable interrupt function with User-Defined Upper and lower threshold settings

5. Temperature and Humidity

This is a multifunctional sensor that gives you temperature and relative humidity information at the same time. It utilizes a DHT11 sensor that can meet measurement needs of general purposes. It provides reliable readings when environment humidity condition inbetween 20% RH and 90% RH, and temperature condition inbetween 0°C and 50°C, covering needs in most home and daily applications that don't contain extreme conditions.

  • Work Voltage: 3.3V ~ 5V
  • Measuring Range:
  • Accuracy:
  • Sensitivity:
  • Signal Collecting Period: 2S

 6. PIR Motion Sensor Module ($7.90 USD)

Highly integrated module popularly used for entry detection, it complies with microcontroller or DC loads.
 
Applications
  • Switch
  • Motion sensor
  • Thief-guarding system
  • Industrial automation
 
Specifications
  • Input voltage: DC 4.5~20V
  • Static current: 50uA
  • Output signal: 0,3V (Output high when motion detected)
  • Sentry angle: 110 degree
  • Sentry distance: max 7 m

7. Water flow sensor

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. 

You will need Seeeduino / Arduino ,Water Flow Sensor,10K resistor,a breadboard and some jumper wires.

Wiring up the Water Flow Sensor is pretty simple. There are 3 wires: Black, Red, and Yellow. Black to the Seeeduino's ground pin Red to Seeeduino's 5v pin The yellow wire will need to be connected to a 10k pull up resistor.and then to pin 2 on the Seeeduino.

 

8. Directional light / flame sensor

The Grove - Flame Sensor can be used to detect fire source or other light sources of the wavelength in the range of 760nm - 1100 nm. It is based on the YG1006 sensor which is a high speed and high sensitive NPN silicon phototransistor. Due to its black epoxy, the sensor is sensitive to infrared radiation. In fire fighting robot game, the sensor plays a very important role, it can be used as a robot eyes to find the fire source.

The module is mainly used to detect the infrared light. It outputs digital signal 0 and 1 through a Comparator output. The output value will be 0 when infrared light is detected. And the sensitivity is adjustable by the precision potentiometer.

Let's use it to control. When the output value is 0, the led will light up.

  • Connect the module to the D3 of Grove - Base Shield using the 4-pin grove cable.
  • Plug the Grove - Base Shield into Arduino.
  • Connect Arduino to PC by using a USB cable.
  • Copy and paste code below to a new Arduino sketch. Please click here if you do not know how to upload.


9. Alcohol sensor

Grove - Alcohol Sensor is a complete alcohol sensor module for Arduino or Seeeduino. It is built with MQ303Asemiconductor alcohol sensor. It has good sensitivity and fast response to alcohol. It is suitable for making Breathalyzer. This Grove implements all the necessary circuitry for MQ303A like power conditioning and heater power supply. This sensor outputs a voltage inversely proportional to the alcohol concentration in air.

  • Input Voltage: 5V
  • Working Current: 120mA
  • Detectable Concentration: 20-1000ppm
  • Grove Compatible connector
  • Highly sensitive to alcohol.
  • Fast response and resumes quickly after alcohol exposure.
  • Long life.
  • Compact form factor.

10.Soil moisture sensor

This Moisture Sensor can be used to detect the moisture of soil or judge if there is water around the sensor, let the plants in your garden reach out for human help. They can be very easy to use, just insert it into the soil and then read it. With the help of this sensor, it will be realizable to make the plant remind you : hey, i am thirsty now, please give me some water.
