Smart Home Sensors - Know What Happens in Every Room, Every Second
A smart home sensor detects motion, door openings, temperature changes, and humidity levels — then sends instant alerts to your phone. You know when your front door opens, when someone walks into a room, or when the AC needs to kick in. HomeMax Smart stocks WiFi-powered smart home sensors starting from Rs 1,200 that integrate with Tuya, Alexa, and Google Home across Pakistan.
Why Pakistani Homes Need Smart Sensors
Pakistan faces unique security and comfort challenges. Load-shedding means you need battery-powered devices. Unpredictable schedules mean you want instant alerts when something happens at home. Manual monitoring is not practical when you are at work or traveling.
Smart sensors solve three core problems:
Security Monitoring: Know when doors open, windows break, or motion is detected in restricted areas. Get alerts on your phone within seconds.
Climate Control: Monitor temperature and humidity in real time. Trigger AC or humidifier automatically when conditions cross your set thresholds.
Energy Management: Detect when rooms are empty and trigger lights or fans to turn off automatically.
Types of Smart Home Sensors We Stock
Motion Sensors (PIR)
Motion sensors detect human movement using passive infrared technology. The sensor reads heat signatures moving across its field of view. When movement is detected, the sensor triggers an alert, activates linked devices, or starts camera recording.
The Tuya WiFi PIR Motion Sensor at Rs 1,800 offers 110-degree detection angle with 12-meter range. Battery powered with 12-month life. Integrates with Tuya smart home system for triggering lights, cameras, or alarms.
The Zigbee PIR Motion Sensor at Rs 2,200 connects through Zigbee mesh network for faster response time under 100ms. Battery life exceeds 2 years on a single CR2032 cell. Ideal for homes with multiple sensors.
Door and Window Sensors
Door sensors detect when a door or window opens using magnetic contact design. Two pieces separate when the door opens, triggering an alert.
The Tuya WiFi Door Window Sensor at Rs 1,200 sends instant phone alerts when any door or window opens. Battery powered with 18-month life. Install on main doors, windows, cabinets, and gates. Pair with smart lights to automatically turn on when a door opens.
The Zigbee Door Sensor at Rs 1,800 offers 2-3 year battery life through Zigbee mesh network. Magnetic contact with 15mm gap tolerance. Faster response than WiFi models.
Temperature and Humidity Sensors
Temperature sensors monitor room climate and trigger AC or humidifier when conditions cross set thresholds.
The Tuya WiFi Temperature Humidity Sensor at Rs 2,500 monitors room climate with 0.1-degree accuracy. Triggers AC or humidifier automatically. Battery powered with 12-month life. Useful for monitoring nurseries, server rooms, and storage areas.
The Zigbee Temperature Humidity Sensor at Rs 2,500 connects through mesh network with 2+ year battery life. Real-time monitoring through Tuya app.
Multi-Sensor Devices
Multi-sensors combine multiple detection types in one device. The Tuya WiFi Multi-Function Sensor combines motion, temperature, and light detection in a single unit. One sensor covers multiple monitoring needs, reducing the number of devices on your walls.

FAQs
Do smart sensors work during load-shedding?
Yes. All our smart sensors are battery-powered with 12-24 month life. They continue working during power outages. WiFi sensors send alerts as long as your router has UPS backup. Zigbee sensors maintain local mesh network even during outages.
How many sensors do I need for a 3-bedroom home?
Typically 6-8 sensors: 2 door sensors on main entries, 4 motion sensors in bedrooms and hallway, 1 temperature sensor in living room, 1 door sensor on main bedroom. Total cost approximately Rs 10,000-15,000.
Can smart sensors trigger other devices automatically?
Yes. Configure rules in the Tuya app: when motion is detected, turn on lights. When door opens, activate camera. When temperature exceeds 28 degrees, turn on AC. Sensors trigger devices through WiFi or Zigbee connectivity.
