Energy Conservation ThroughSensing TechnologyBangkok, Thailand

182 Sensor Switches Delivered to MRTA Head Office, a State-Owned Enterprise in Thailand.
Advancing Energy Conservation in Buildings Using Automatic On/Off Lighting.
182 Panasonic sensor switches have been installed in the headquarters andsecond building of the Mass Rapid Transit Authority of Thailand (MRTA), astate-owned transportation corporation. MRTA is operating the Mass Rapid
Transit (MRT) system in Bangkok and its vicinity, including in other provinces andbetween provinces, in accordance with the Royal Decree. MRT was built to meetthe growing transportation demand in the Bangkok metropolitan area and to
alleviate chronic traffic congestion, contributing to the improvement of the urban
environment by aiding the area’s economic development while reducing
greenhouse gas emissions.
In recent years, MRTA has also been focusing on energy conservation measures
for its facilities by converting lighting fixtures to LED, retrofitting energy-efficient
air conditioning systems, and using sensors, actively participating in the global
efforts for decarbonization.

What are PIR Motion Sensors?
When connected to lighting fixtures, Passive Infrared (PIR) Motion Sensors automatically turn lights on when a person
approaches and automatically turns lights off at a set amount of time after people leave the area. When a person entersa sensor’s detection area, the sensor detects the temperature change caused by the person’s activity and converts it
into an electrical signal.

Automatic On/Off of Lighting for Convenience and Energy Saving.
Installing PIR Motion Sensors improves theconvenience and safety of a space as it eliminates
the need to turn switches on and off. As lights areturned on automatically when people are present
and turned off automatically when there are nopeople present, PIR Motion Sensors saveelectricity and reduce CO 2 emissions.
Through this initiative, MRTA is promoting
awareness of energy conservation within thecompany.

Choose the Best Sensor to Fit Your Needs and Space
Panasonic offers a wide range of PIR Motion Sensors to fit various spaces and needs. The sensors that Panasonic supplied
to MRTA this time are interconnectable types (WTKG2411 and WTKG2911), which cover large areas with the multi-point
detection system. The sensors are widely used at entrances and hallways where people often come and go.
By installing multiple sensors in a single lighting circuit, the system can detect human presence and activity levels in all
directions and control the lighting accordingly. In addition, the newly delivered sensors are equipped with PaPIRs,
proprietary products developed by Panasonic. From the sensor lenses to the overall design, the PaPIRs were created toachieve high detection performance and reliability.

Sensors are installed at entrances and in front ofelevators where people come and go. The high detection
function detects human presence and activity levels in all
directions.

Lights automatically turn on and off without people
needing to touch switches, reducing hygienic concerns
about touching switches in restrooms.

Lights in the hallways are also
automatically turned on when thesensors detect human presence,and the lights are automaticallyturned off when no one is there.
