IOT BASED GREEN HOUSE MONITORING AND

CONTROLLING SYSTEM

B L O C K D I A G R A M

A b s t r a c t:

Green House systems are need of more growth in less time. Green house effect is increasing because pollution is increasing. So naturally there is imbalance in temperature, water level or humidity. So to grow a natural crop is seriously a

challenge for our farmers. So here we are designing a system which will work in critical conditions and will maintain desired temperature, humidity level and light fading. So our crop will grow with sufficient minerals and vitamins. And the

Green House parameters will be checked from any places i.e. no need to go to farm or the place where system is implemented.

W O R K I N G:

• Controlling:

In this project we have used three sensors –

1. LDR the light sensor

2. Humidity sensor

3. Temperature sensor

These sensors give outputs in analog form. ADC is used to convert

these analog signals into digital signals. And these converted digital

signals are given to Micro-controller 8051(AT89s52).

Micro-controller checks the signal levels, compares them with the

conditions of maintaining green house balance takes proper action

according to the conditions it is facing.

e.g. Tomato needs temperature between 14-16 degree celcius to

grow. So we divided the temperature(T) level into three levels (1)

Medium: 14<T<16 (2) Low: T<14 (3) High: T>16. Now when level is

low Microcontroller will ON the heater, when level is high

Microcontroller will ON the cooling fan and at Medium level it will

off heater and cooling fan both.

Similarly we can say that it uses humidity sensor and light sensor

and makes water pump and lamp ON-OFF respectively. Relays are

just used as switching element and relay driver circuit to interface

relay with microcontroller. Controlling part is automatic after

making system ON. In the critical conditions we use RESET to

protect our system over damage threat.

• Monitoring:

Here we will monitor Green House parameters using internet of

things at any place in the world. We are using Windows laptop to

monitor and program the chip. Using RS232 port we will get status

of Green House system parameters through 8051 on our laptop.

And then that data is uploaded over cloud through our web server

and is made accessible over internet to our users.

A p p l I c a t I o n s:

Air temperature control

Humidity control

Soil condition control

Light fading control

Can be used in Greenhouses, Botanical gardens and farms.

A d v a n t a g e s:

This project is automated and does not require any human attention.

For monitoring IoT is used so person can monitor the temperature,

humidity level etc. from his home easily.

Laptop is used for controlling and programming so system is portable.

We can easily modify the controlling program and change the criteria

as required.

Can be easily implemented.
