What is IoT?
At Extranet Systems, we believe IoT is the future. The Internet of Things (IoT) describes a network of physical objects—"things"—embedded with sensors, software, and other technologies to connect and exchange data with other devices and systems over the Internet. Extranet Systems works with your business to customise an IoT solution that best fits your requirements.

Environmental Monitoring Sensors
 |
 |
 |
|
|---|---|---|---|
| Feature | Magnetic Gate Switch | Temperature and Humidity Sensor | Leak Detection Sensor |
| Primary Function | Detects open/closed status of doors/gates | Measures ambient temperature and humidity | Detects presence of water or liquid leakage |
| Sensing Principle | Magnetic field (reed switch or Hall effect) | Thermistor, capacitive/semiconductor sensor | Conductivity, resistance, or optical-based |
| Typical Output | Digital (ON/OFF) | Analog or Digital (depending on model) | Digital (leak detected or not) |
| Power Requirement | Low to moderate | Low to moderate | Low to moderate |
| Installation Location | On gates, doors, cabinets | Indoor (offices, server rooms), outdoor with enclosure | Under appliances, near pipes or tanks |
| Use Case Examples | Home security, industrial gate control | HVAC systems, environmental monitoring, greenhouses | Data centers, smart homes, industrial fluid control |
| Maintenance | Minimal | Sensor cleaning may be required | Sensor cleaning or replacement may be needed |
| Communication Protocols | Simple wiring, can integrate with microcontrollers | I2C, SPI, analog voltage output, digital interfaces | Wired or wireless signals to alarms or controllers |
| Cost | Low | Low to moderate (depending on accuracy) | Low to moderate |
| Sensitivity | Binary detection (closed/open) | Varies by model; some very sensitive | Detects small to large leaks depending on design |
