3. Centralized Environment and Battery
Monitoring System For Server Rooms
Essentiality:
Monitoring is always important for running system
Environment condition can have very bad impact
on a system.
50-100 billion dollar loss (research showed/year)
Data center face downtime [2]
23% ---- 5 times in a year
61% ---- 1-4 times in a year
16% ---- Don’t face downtime

Centralized Environment and Battery
Monitoring System For Server Rooms

10. 1. Room Temperature:
Electronic equipment age is decreased when it
gets hot, Cooler environment is always better
and friendly to electronic equipment.
Used LM35 temperature sensor.
For calculation we use formula;
T= ((ADC value)/512)*150)
“T” is in degree centigrade.
A. PARAMETER SENSOR

11. 2. Humidity:
Humidity is monitored by humidity sensor
HS1101
Capacitive type sensor
Able to operate from 0% to 100% relative
humidity.
Conditions should be maintained such that
condensation does not happen.
A. PARAMETER SENSOR

12. A. PARAMETER SENSOR
3. Smoke Sensor:
Sensors detect the smoke and generate alarm.
Smoke detector module LM393 MQ2 is used
for smoke detection.
The analog output voltage is 0-5V, the higher is
the concentration, the higher is voltage.

13. 4. Water Sensor:
Water sensors detect the water in the server
room and generate alarm.
Sensors consist of two wires; one is connected
with microcontroller digital pin and other wire
terminal places some near distance and
connected with positive 5 volt.
A. PARAMETER SENSOR

14. 5. Battery Status
Indicator (BSI):
BSI indicates that the
battery is connected
with load or not and
percentage of charging
of 6 volt battery used in
controller.
A. PARAMETER SENSOR
Charge Percentage (%) Voltage (Volt)
100 6.37
90 6.31
80 6.25
70 6.19
60 6.12
50 6.05
40 5.98
30 5.91
20 5.83
10 5.75

Percentage of charges according to voltage

15. 6. Battery Life Monitor
 We estimate the expected life of the battery (in 100 %,
75%, 50%, 25% ) by finding the different parameters of
battery by measuring [5][9][10].
 Battery terminal voltage (open circuit and closed circuit),
 Current drawn
 Internal resistance (when battery is fully charged)
 Estimate by Internal Resistance using equation [9].
Voc =Vst + I*r
 “Voc” is the open circuit voltage or terminal voltage.
 “Vst” is the voltage when switch is closed.
 “r” is the internal resistance of battery.
 “I” is the current across the series load resistance RL = 100 ohms when switch closed.
A. PARAMETER SENSOR

16. TRANSMITTER :
Transmitter collects the data of different
parameters of server room from sensor unit and
makes a monitor network packet in CCS compiler
using SPI master communication of one byte in
transmitter controller (PIC 16F877a).
Then transmit through wire and other RF
transmitter module (315-MHz). Schematic
Proteus simulation diagram of transmitter is
shown in Fig-5.

18. RECEIVER:
Receiver connects with the wire and RF receiver
module.
Receiving module (315-MHz) collects a data
packet and sends to the receiver controller (PIC
16F877a).
Controllers first de-packetize a packet and then
make a string of parameter and drive to the
computer through PC port (RS232). Schematic
Diagram of Receiver is shown in Fig-8.

20. GRAPHICAL USER INTERFACE:
A graphical user interface (GUI) is a human-
computer interface.
Designed GUI in Visual C-sharp, which display
the parameters
It generates the graph in real time by clicking
on stored data (Fig. 10) and graph of whole
day would be display as appeared in Fig. 9.
