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. Kindly remove the protective film before usage. It is advisable to preheat the module for at least 24 hours. Detection range: 10-1000 ppm.

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 arduino 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.

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.
