Field Of Invention
[0001] The present work was undertaken to conduct a novelty search on "LOW COST HERBAL
MOSQUITO REPELLENT USING ARM BASED DEVICE". More specifically it relates to a unique, lowcost,
home-made, eco-friendly product which is a unique sensor that automatically sense the mosquito
density and then regulate the quantity of fumes of our unique solution which is specially prepared from
the herbal components, in order to repel mosquitoes as well as purify the air.
Background Of The Invention
[0002] Due to the rising number of mosquito borne illnesses, control of mosquitoes is something of
utmost importance in the present day. These mosquitostare rapidly growing in number day by day. So a
strong mechanism is needed to stop breeding of mosquitos.
[0003] Though there are many chemical based mosquito repellents available in the market, but they
are harmful and expensive. So there is a strong need to develop a mosquito repellant that is of low cost,
portable, smart and quite eco-friendly in nature.
[0004] The Sensors which we used in our project is built on Arduino Board (ARM Based Board), which
is of low cost, portable and can be easily deployable in any situation.
{0005] This sensors is highly efficient to capture mosquito's signals spreading in a room and then take
immediate action in order to repel mosquitos..
Objectives Of The Invention
[0006] It is an object of the invention to prepare a 100% herbal product based on low cost sensors
' which is capable of repelling mosquitoes in a given area.
[0007] It is an object of the invention to provide a low cost and unique mosquito repellant product that
is eco-friendly to nature and keeps the environment clean and improve the air quality.
[0008] It is an object of the invention to develop a Herbal Mosquito repellant that have no side effect
on environment where it is used.
o) [0009] It is an object of the invention to provide low cost yet effective portable sensor which

[00011] It is an object of the invention to provide low cost yet effective mosquito repellant solution that
employs locally available materials as components, instead of high price chemicals that make available
mosquito repellants:
Summary Of The Invention
[00012] The present invention discloses the studies directed towards the development of safe and
efficient herbal mosquito repellant formulations obtained, by mixing a solutions of 20ml Neem extract,
20ml Tulsi Oil, 20ml Turmeric Oil, 20ml Orange Peel Oil, 20gm Clove. This unique solution is composed
of herbal components and thus has no side effects on the human beings. This innovation also defines a
unique mosquito repellant sensor which is based1 on the density of mosquito in a given area. This
innovation describes a unique approach through which this sensor automatically sense the mosquito
density and then regulate the quantity of fumes of our unique solution which is specially prepared from
the herbal components, in order to repel mosquitoes as well as purify the air. We conducted several tests
on different compositions and mosquito density and thus we conclude that our approach is better and
unique than other existing mosquito repellants available in the market.Brief Description Of Drawings

Detailed Description The selection of the plants was based on their availability as raw material, scientific evidence and
folkloric use as mosquito repellants.
[00017] Selection of Ingredients
Cymbopogonnardus (Citronella)
Citronella essential oil is extracted by steam-distillation, of citronella leaves. Citronella essential oil is
used as an insect repellent and it can be found in dozens of registered pesticide products such as sprays,
lotions and candles. Due to its antifungal properties, citronella oil is also used to treat insect bites.
Eucalyptus globulus
S. Eucalyptus is named as "Blue Gum" Eucalyptus essential oil which is extracted by steam-distillation
of eucalyptus leaves is taken orally for pain and inflammation of respiratory tract mucous membranes,
coughs, asthma and bronchitis. It is also used as an antiseptic, insect repellent and treatment option for
wounds.
Curcuma longa (Turmeric)
Turmeric is mainly used in culinary preparations and for medicinal purposes. For chemical purposes, it
is used as an indicator and can identify a base. Turmeric turns red when it comes in contact with a base.
Monoterpene hydrocarbons (46.9%) constitute the bulk of the Curcuma longa rhizome essential oil which
is obtained by hydro-distillation and has antiseptic and anti-carcinogenic properties.
Ocimum sanctum (Tulsi)
Tulsi essential oil has antibacterial, anti-viral and anti-fungal properties as well. Tulsi essential oil is also
used in massage oils, perfumes, aromatherapy baths, soap making and candle making.Syzygiumaromaticum (Clove)
Clove essential oil is widely used and well known for its medicinal properties. Traditional uses of clove
oil include use in dental care as an antiseptic and analgesic. The oil is active against oral bacteria
associated with dental caries and periodontal diseases. Additionally, clove oil has anti-carcinogenic, antiallergic,
anti-oxidantand insecticidal properties.
Citrus sinensis (Sweet Orange)
Orange fruit. Sweet Orange peels, leaves and flowers contain fine essences of oils that are used in the
manufacture of cosmetic products and medicines. The main chemical components of Sweet Orange peel
essential oil are a-pinene, sabinene, myrcene , limonene, linalool, citronellal, neural and geranial.
Azadirachtaindica (Neem)
All parts of the tree such as seeds, leaves, flowers and bark, are used in the preparing of various
different medical preparations. Neem products have medicinal properties that prove to be anti-fungal, antidiabetic,
antibacterial, antiviral and anti-fertility. Limonoid compounds contained in Neem seed extract
seem to have the insecticide and pesticide properties. The main limonoid in Neem seed extract is
azadirachtin.
[00018] Preparation of the Plant Extracts:
Neem seeds 2, 966.67 g, were soaked in hexane solvent, 1,960 ml, overnight at room temperature with
occasional shaking. The hexane extract was filtered and the filtrate was concentrated by evaporator at
around 45°C. Same procedure was carried out for the second extraction using squeezed Neem seeds.
Finally, the total extract, was weighed and stored in refrigerator until it was used for the experiment. The
leaves that were extracted with hexane were soaked in ethanol solvent, 3, 000 ml, for one day at room
temperature. Then the ethanol extract was filtered and the filtrate was concentrated. Same procedure was
carried out for the second extraction using squeezed Neem leaves. Finally, the total extract was weighed
and stored in refrigerator at 4°C until it was used for the experiment. For the experiment, hexane extract of
Neem and ethanol extract of Neem were mixed together in 1:1 ratio.
[00019] Preparations of the Essential Oils:
Hydro-distillation process was separately performed for Ocimum sanctum (Tulsi) leaves 7, 718.90 g;
Curcuma longa (Turmeric) rhizomes 8, 9, 700.00 g; Citrus sinensis (Sweet Orange) peels 3, 1,144.52 g.
Water was added to the weighed quantity of plant material in a round bottom flask which was placed on a
heating mantle . Flow of water was allowed to run in the condenser. Heat the solution and extract out the
necessary oils were extracted during the.distillation process.
[00020] Preparation of the Test Solutions:
10% (v/v%) plant extract or essential oil containing ethanol solutions were prepared using each plant
extract and essential oil .Each plant extract or essential oil was mixed . Then ethanol was added until the
S> volume was 6 ml.
