Western Sydney University Solar Powered People Counting
PowerStack: Solar Powered People Counting
Discover how Western Sydney University & Cohera-Tech harnessed the sun in a hard-to-reach site to measure usage of a new access point to campus.

The Challenge:
When Western Sydney University wanted to measure the success of a new light rail stop providing access to the Parramatta South Campus, they needed a people counter but didn’t want to run power or data cables to the site. Cohera-Tech’s sensors can use a customisable 4G kit to transmit the data but do need a small amount of power to facilitate that.
The Solution:
Cohera-Tech partnered with Western Sydney University, PowerStack and Reliant Electrical to utilise and modify a solar powered array built into a five-metre fixed pole structure. PowerStack delivers 100% off-grid solar power with no cabling or trenching. The pole generates enough solar power to its batteries to power both the sensor and the 4G modem.
The Results:
Universities have long known the power of people counting to measure occupancy and space utilisation on campus. By leveraging Cohera-Tech's insights, they can work to optimise room bookings and room utilisation. In this case, they are now able to measure the ROI of a newly opened light rail stop – was it being used?, how frequently?, what times? etc – on a continuing and ongoing basis.
This data provides a powerful tool for strategic decision-making, which has become a key ingredient in Western Sydney University’s continued success in attracting students to campus.
