Use Case: Environments with existing Wi-Fi infrastructure (homes, offices, commercial buildings).
Key Features:
● Connectivity Range: Limited by Wi-Fi signal strength; ideally stronger than -80 dBm
● Signal Tip: Wi-Fi strength can be estimated using a smartphone—2 or more bars indicates suitable signal for stable operation.
● Maximum Number of Devices: up to 200 devices (depends on the Wi-Fi router’s available DHCP IP address pool and its ability to handle multiple simultaneous connections).
● Controllers: ESP8266 D1 Mini, ESP-01, ESP32, Raspberry Pi Pico W, Particle Photon 2, B-WiFi-01
● Sensors: DS18B20 (temperature), DHT11/DHT22 (temperature & humidity), BME280 (temperature, humidity, pressure)
● Power Supply: 5V DC, 12V DC
● Power Consumption: 70–200 mA

Use Case: Ideal for environments with existing industrial or building infrastructure, especially where Wi-Fi or Ethernet is unavailable or unreliable. LoRa is well-suited for long-range, low-power applications such as environmental monitoring, asset tracking, or remote telemetry.
Key Features:
● Connectivity Range: Up to 10 km in open-space, line-of-sight conditions (no forest or buildings). Actual range depends on radio signal strength, interference, terrain, and the height of the gateway antenna (higher placement is better).
● Device Capacity: Supports up to 2,000 nodes per network (depends on node activity rate and gateway performance).
● Gateway Requirement: At least 1 LoRa gateway is required to collect data from nodes and forward it to the internet (cloud server or local infrastructure).
● SyncMaster (Time Coordinator): A specialized device that synchronizes transmission timing across all nodes to reduce signal collisions and optimize airtime usage.
● Sensors: DS18B20 (temperature), DHT11/DHT22 (temperature & humidity), BME280 (temperature, humidity, pressure)
● Power Supply Options:
- 5V DC / 12V DC
- 3.7V Li-ion or LiPo battery
- Standard 3V battery for ultra-low-power nodes
● Battery Life: Up to 2 years of autonomous operation (based on controller type, sensor choice, and deep sleep interval configuration)

At N3xar , we understand that every monitoring task—whether it’s temperature, humidity, or pressure—comes with its own unique set of requirements. The cost of implementing an IoT solution can vary significantly based on several factors, including:
● Data Transfer Technology: Different technologies (Wi-Fi, LoRa, Ethernet, etc.) have varying costs and capabilities.
● Type of Controllers and Sensors: The specifications and features of the devices you choose will impact the overall price.
● Environmental Conditions: The conditions in which the devices will operate can affect the selection of appropriate hardware.
● Deployment scale: Number of devices, power source, installation complexity
