REDUCE YOUR ELECTRICITY BILL
Amitek Security Equipmets Pvt Ltd., a company working in the field of Energy Saving has introduced Passive Infrared sensor (PIR) / Motion sensor for automatic control of lights. The PIR Sensor Switch can detect the Infrared Rays released by human body. The light or any other electrical appliance can be activated automatically by the active presence of a human body within the detection range / coverage area & when there is no presence the light will be deactivated automatically by the use of PIR Sensor, considerable energy can be saved by switching off the lights when the space is not in use. Savings are huge in larger facilities.By the use of PIR Sensor, considerable energy can be saved by switching off the lights when the space is not in use. By installing PIR Sensors more than 50 % of electricity bill can be saved. These sensors have excellent performance, good life & are very useful in reducing your electricity bill.
Working Principle: -
The PIR Sensor senses the motion of a human body by the change in surrounding ambient temperature when a human body passes across.
Then it turns on the lighting load to which it is connected.
The lighting load will remain ON until it senses motion.
Once the motion is seized it switches OFF the lighting load.
During the night, the LUX adjustment knob allows you to adjust the luminosity based on which the lighting load will either switch on / off automatically.
PIR Motion Sensors will itself recover its cost by reducing your electricity bills and will further save your electricity cost for the future.
Very easy installation and can be installed by in – house technician itself.
No separate wiring is required hence no additional installation cost.
No modification is required and complies with current aesthetics.
Pay back within ten months according to residential meter and six months according to construction meter.
|S.No.||For Commercial Meter||Without PIR Motion Sensor||With One PIR Motion Sensor|
|1||Power capacity of total connected light’s load||2000 watts||2000 watts|
|2||Operational hours of connected light’s load||12||6|
|3||Total consumption in watts per day||24000||12000|
|4||Number of days in a month||30||30|
|5||Total power used by connected light’s load in KW||720000W = 720 KW||&360000W = 360 KW|
|6||Cost of electricity per KW in Rupees||10||10|
|7||Amount paid per month @ Rupees 10 per unit||7200.00||3600.00|
|8||Savings per month on connected light’s load in Rupees||0||3600.00|
Investment on One PIR sensor = Rupees 2350.00 Rupees 3600 recovered in 30 days (As per above table) Rupees 2350 recovers in how many days?
= 2350/3600 X 30 days = 19.58 or say 20 days
If Sensor is used for 12 Months, you will save Rupees 43200 (12 months X Rupees 3600).
Therefore cost saving in 1st year will be Rupees 43200 – 2350 (cost of one PIR) = Rupees 40850/-
Not only you will recover the cost of one PIR Sensor but also you will save electricity worth of Rupees 40850/- in 1st year & Rupees 43200 for every next years. Moreover the approximately life of sensor is minimum 5 to 6 years, therefore in 5 years you can save Rupees 2, 13,650/- (1st year x 40850 & for 2nd, 3rd, 4th & 5th year Rupees 43200 each).
