Smoke

Smoke is a suspension of airborne particulates and gases emitted when a material undergoes combustion or pyrolysis, together with the quantity of air that is entrained or otherwise mixed into the mass. It is commonly an unwanted by-product of fires, but may also be used for pest control, communication, defensive and offensive capabilities in the military, cooking, or smoking. It is used in rituals where incense, sage, or resin is burned to produce a smell for spiritual or magical purposes. It can also be a flavoring agent and preservative.

Smoke inhalation is the primary cause of death in victims of indoor fires. The smoke kills by a combination of thermal damage, poisoning and pulmonary irritation caused by carbon monoxide, hydrogen cyanide and other combustion products. Smoke is an aerosol of solid particles and liquid droplets that are close to the ideal range of sizes for Mie scattering of visible light.

Fermion: MEMS Smoke Gas Detection Sensor

Fermion: MEMS Smoke Gas Detection Sensor employs state-of-the-art microelectromechanical system (MEMS) technology, endowing the sensor with compact dimensions, low power consumption, minimal heat generation, short preheating time, and swift response recovery. The sensor can measure smoke concentration qualitatively and is suitable for smoke alarm and other application scenarios.

Precautions for use:

  • Kindly remove the protective film before usage.
  • To prevent exposure to volatile silicon compounds vapors.
  • Refrain from prolonged exposure to extreme environments.
  • Avoid contact with water, condensation, and freezing.
  • Minimize excessive vibration, impact, and dropping.
  • For extended periods of non-usage, it is advisable to preheat the module for at least 24 hours.

Soil Moisture

Soil moisture is the critical parameter in agriculture. If there is a shortage or overabundance of water, plants may die. At the same time, this data depends on many external factors, primarily weather conditions and climate changes. That is why it is so vital to understand the most effective methods for analyzing soil moisture content.

This term refers to the entire quantity of water in the ground’s pores or on its surface. The moisture content of soil depends on such factors as weather, type of land, and plants. The parameter is vital in monitoring soil moisture activities, predicting natural disasters, managing water supply, etc. This data may signal a future flood or water deficit ahead of other indicators.

Soil moisture affects:

  • Content of air, salinity, and amount of toxic substances.
  • Ground structure and thickness.
  • Temperature and heat capacity of the ground.

Gravity: Analog Soil Moisture Sensor

A soil moisture sensor can read the amount of moisture present in the soil surrounding it. It’s an ideal for monitoring an urban garden, or your pet plant’s water level. This is a must have component for a IOT Garden / Agriculture. The new soil moisture sensor uses Immersion Gold which protects the nickel from oxidation. Electroless nickel immersion gold has several advantages over more conventional surface platings such as HASL, including excellent surface planarity, good oxidation resistance, and usability for untreated contact surfaces such as membrane switches and contact points.

This Soil Moisture Sensor uses the two probes to pass current through the soil, and then it reads that resistance to get the moisture level. More water makes the soil conduct electricity more easily, while dry soil conducts electricity poorly. This sensor will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden.

Fermion: BLE Sensor Beacon

BLE Beacon, also known as Low Energy Bluetooth Beacon, is a small wireless device that broadcasts signals using BLE technology. Due to its broadcast nature, pairing is not required between the beacon and receiving devices. Each beacon contains a unique identifier, detectable by nearby devices equipped with Bluetooth technology, such as ESP32 and smartphones supporting BLE scanning.

This Bluetooth beacon has a built-in 11-bit ADC, Fermion version, and multiple I/Os that can be multiplexed to SDA/SCL while broadcasting over Bluetooth. Users can access sensor data within broadcast range on a Bluetooth-equipped device such as a Smartphone or ESP32. This BLE beacon has a built-in 11-bit ADC and an I2C interface, allowing it to real-time collect and broadcast data from various types of sensors, including analog, digital, and I2C sensors.

SparkFun Triple Axis Accelerometer Breakout – MMA7361

This is a breakout board for Freescale’s MMA7361L three-axis analog MEMS accelerometer. The sensor requires a very low amount of power and has a g-select input which switches the accelerometer between ±1.5g and ±6g measurement ranges. Other features include a sleep mode, signal conditioning, a 1-pole low pass filter, temperature compensation, self test, and 0g-detect which detects linear freefall. Zero-g offset and sensitivity are factory set and require no external devices.

This breadboard friendly board breaks out every pin of the MMA7361L to a 9-pin, 0.1″ pitch header. The sensor works on power between 2.2 and 3.6VDC (3.3 Volt optimal), and typically consumes just 400µA of current. All three axes have their own analog output.

  • Two selectable measuring ranges (±1.5g, ±6g)
  • Breadboard friendly – 0.1″ pitch header
  • Low current consumption: 400 µA
  • Sleep mode: 3 µA
  • Low voltage operation: 2.2 Volt – 3.6 Volt
  • High sensitivity (800 mV/g at 1.5g)
  • Fast turn on time (0.5 ms enable response time)
  • Self test for freefall detect diagnosis
  • 0g-Detect for freefall protection
  • Signal conditioning with low pass filter
  • Robust design, high shocks survivability

PIR Motion Sensor (JST)

This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the “Alarm” pin will go low. This unit works great from 5 to 12 Volt. The alarm pin is an open collector meaning you will need a pull up resistor on the alarm pin. The open drain setup allows multiple motion sensors to be connected on a single input pin. If any of the motion sensors go off, the input pin will be pulled low.

At their most fundamental level, PIR sensor’s are infrared-sensitive light detectors. By monitoring light in the infrared spectrum, PIR sensors can sense subtle changes in temperature across the area they’re viewing. When a human or some other object comes into the PIR’s field-of-view, the radiation pattern changes, and the PIR interprets that change as movement. All that’s left for us to connect is three pins: power, ground, and the output signal.

NeoPixels

The WS2812 Integrated Light Source, or NeoPixel in Adafruit parlance, is the latest advance in the quest for a simple, scalable and affordable full-color LED. Red, green and blue LEDs are integrated alongside a driver chip into a tiny surface-mount package controlled through a single wire. They can be used individually, chained into longer strings or assembled into still more interesting form-factors.

NeoPixels don’t just light up on their own; they require a microcontroller, such as Arduino, and some programming. We provide some sample code to get you started. To create your own effects and animation, you’ll need some programming practice. If this is a new experience, work through some of the beginning Arduino tutorials to get a feel for the language.

NeoPixel Stick – 8 x 5050 RGB LED

Make your own little LED strip arrangement with this stick of NeoPixel LEDs. We crammed 8 of the tiny 5050 smart RGB LEDs onto a PCB with mounting holes and a chainable design. Use only one microcontroller pin to control as many as you can chain together. Each LED is addressable as the driver chip is inside the LED. Each one has constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you’re ready to rock. The LEDs are “Chainable” by connecting the output of one stick into the input of another. There is a single data line with a very timing-specific protocol.
