Occupancy, motion, presence and daylight sensor systems for commercial buildings in Visakhapatnam — surveyed, designed, installed, programmed and maintained by LiveInSmart Technologies.
LiveInSmart Technologies installs commercial occupancy, motion, presence and daylight sensor systems across Visakhapatnam, Andhra Pradesh — covering Rushikonda, Madhurawada, MVP Colony, Dwaraka Nagar and surrounding commercial areas. We handle the full scope: site survey, coverage design, product selection, installation, programming, lighting and HVAC/BMS integration, commissioning and AMC. Savings are assessed per building during the survey rather than promised upfront.
Visakhapatnam combines port and industrial operations with a growing IT and commercial base at Rushikonda and Madhurawada. Sensor strategy here has to handle both high-bay industrial sheds and glazed sea-facing offices, which are two very different detection problems.
Coastal humidity and salt-laden air affect device selection — we specify IP-rated enclosures for external and semi-open areas and avoid ultrasonic devices where strong HVAC airflow causes false triggers. Sea-facing glazed offices benefit heavily from daylight harvesting on the perimeter.
Full-scope delivery — you deal with one team from survey to annual maintenance.
Our Visakhapatnam project teams work across Rushikonda, Madhurawada, MVP Colony, Dwaraka Nagar, Gajuwaka, Steel Plant area, Siripuram, Beach Road and neighbouring commercial zones.
Sensor strategy is tuned to the operating pattern of each sector in Visakhapatnam.
The same technology comparison our design team uses on every survey — matched to the spaces in your building.
| Sensor Type | How It Detects | Typical Coverage | Accuracy / Weakness | Recommended Areas |
|---|---|---|---|---|
| PIR (Passive Infrared) | Infrared heat movement across the lens field | 6–12 m radius, ceiling mount at 2.7–3.5 m | Reliable on walking motion; misses seated, still occupants and needs line of sight | Corridors, staircases, storerooms, restrooms, cabins |
| Ultrasonic | Doppler shift in reflected high-frequency sound | 8–15 m, works around partial obstructions | Very sensitive to minor motion; can false-trigger on HVAC airflow | Restrooms with cubicles, L-shaped corridors, parking bays |
| Microwave / Radar | Doppler shift in reflected microwave energy | 10–20 m, penetrates thin partitions and glass | Long range and robust; over-detection through walls needs tuning | Warehouses, high-bay areas, basement parking, outdoor lighting |
| Dual Technology (PIR + Ultrasonic) | Requires both technologies to agree before switching | 8–14 m | Highest false-trigger immunity; higher unit cost | Open offices, classrooms, labs, meeting rooms |
| mmWave Presence (60 GHz / 24 GHz) | Millimetre-wave radar detects micro-motion, breathing and posture | 5–8 m, zone-configurable with people counting | Detects motionless occupants; premium cost, needs commissioning | Boardrooms, executive cabins, hybrid meeting rooms, focus pods |
| Daylight / Photocell | Measures ambient lux at the work plane | Per-zone or per-fixture | Saves most in glazed perimeters; requires correct lux setpoint | Glass facades, reception, atriums, perimeter open offices |
Where sensor automation typically reduces energy use, and how we verify it on your site.
| Space Type | Primary Sensor | Where the saving comes from | How we verify it |
|---|---|---|---|
| Private cabins | Dual technology | Lights and FCU left on in empty cabins | Runtime logs before and after |
| Open-plan office | Dual tech + daylight | Perimeter daylight and after-hours zones | Zone metering or lighting-control data |
| Meeting / boardrooms | mmWave presence | Rooms lit and cooled between bookings | Occupancy vs runtime comparison |
| Corridors & staircases | PIR | Full lighting through low-traffic hours | Circuit runtime logs |
| Restrooms | Ultrasonic / PIR | Continuous lighting and exhaust | Runtime and usage counts |
| Basement parking | Microwave | 24×7 driveway lighting | Circuit metering |
| Warehouse high-bay | Microwave / high-bay PIR | Unused aisles fully lit | Aisle-level runtime data |
Every deployment follows the same engineered sequence. Nothing is switched on before coverage is verified and the facility team is trained.
One Partner. One Team. Complete Commercial Automation Solution. Most sensor projects fail not because the hardware is wrong, but because coverage, time delays and HVAC interlocks were never engineered. We own the entire chain.

High-bay microwave sensors mounted at 8–12 m with per-aisle zoning are the right choice. They tolerate dust and cover long aisles, and corridor-mode dimming keeps neighbouring aisles safely lit at reduced output.
Indoor conditioned areas are unaffected. For semi-open corridors, parking and external areas we specify IP65-rated devices with corrosion-resistant housings, which is standard practice in our Vizag deployments.
Yes. We deliver occupancy, presence and daylight sensor projects for IT and corporate offices at Rushikonda, Madhurawada, MVP Colony and Dwaraka Nagar, including BMS integration where the building supports it.
An occupancy sensor is a device that detects whether a space is being used and automatically switches or dims lighting, and optionally HVAC, based on that. In commercial buildings it typically combines PIR (passive infrared) and ultrasonic detection, is ceiling or wall mounted, and holds the load on for a programmed time delay after the last detected activity.
A motion sensor needs movement — usually someone walking — to keep the load on, so it suits corridors, staircases and parking. A presence sensor, typically mmWave radar, detects micro-motion such as breathing and small posture shifts, so it keeps lighting and HVAC on for people sitting still in meetings. Presence sensors cost more but eliminate the classic 'lights switch off during a presentation' complaint.
Yes. Occupancy sensors can drive HVAC through a dry-contact relay to a VRV/VRF indoor unit, an occupancy input on an FCU thermostat, or as a BACnet/Modbus point into a BMS. The usual strategy is an unoccupied setback of 2–3 °C rather than a hard shutdown, so the space recovers quickly when occupied again.
mmWave presence sensors, or dual-technology PIR + ultrasonic sensors, are correct for conference rooms. Both keep lighting on for seated, motionless occupants. Pure PIR is a poor fit for meeting rooms because it needs walking motion and will switch off mid-meeting.
Savings depend on how long lights and HVAC currently run in empty spaces, operating hours, glazing and tariff, so we do not quote a fixed figure before a survey. Corridors, washrooms and parking usually show the clearest reduction because they are often lit continuously. Where a business case is needed, we measure a representative area before and after.
Yes. Sensors integrate with a Building Management System through BACnet/IP, Modbus TCP, KNX or a DALI-2 gateway. Once integrated, occupancy becomes a data point the BMS can use for scheduling, alarms, space-utilisation reports and energy dashboards.
Malls typically use a mix: microwave sensors for basement parking and service corridors, daylight sensors on atriums and glazed facades, dual-technology sensors in back-of-house offices, and ultrasonic or PIR in washrooms. Public retail floors normally stay on scheduled scenes rather than occupancy control during trading hours.
For open-plan offices, dual-technology sensors combined with daylight harvesting give the best balance of savings and false-trigger immunity. For cabins, dual technology alone is sufficient. For boardrooms and hybrid meeting rooms, mmWave presence sensors are the right choice.
A PIR (passive infrared) sensor detects heat movement across its lens segments. It is inexpensive, needs clear line of sight, and works best where people walk — corridors, staircases, storerooms, lobbies and restrooms. It is not suitable where occupants sit still.
An mmWave presence sensor uses millimetre-wave radar (24 GHz or 60 GHz) to detect micro-motion including breathing, so it registers a completely still occupant. Many models also support configurable detection zones and people counting, which makes them useful for both automation and space-utilisation analytics.
In most cases yes. Switched LED circuits can be controlled with relay-based sensors. For dimming and daylight harvesting, the drivers must support DALI, 0–10 V or a compatible wireless protocol; if they do not, drivers or fixtures are replaced in the affected zones only.
Both. Wired DALI-2 or KNX systems suit new fit-outs and large floor plates where cabling is possible. Wireless mesh sensors suit occupied buildings and retrofits where ceiling work must be minimised. We recommend one over the other after the site survey, based on ceiling access and project timeline.
