1. IOT BASED GREEN HOUSE MONITORING AND
CONTROLLING SYSTEM

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.
