This article explores the fundamentals of Zigbee sensors and lists several vendors offering Zigbee-based sensors, including humidity, temperature, lighting, optical smoke, and magnetic sensors. Zigbee’s versatility makes it ideal for diverse applications, from home automation to industrial control. Let’s delve into the world of Zigbee sensors, using the Xbee sensor as a primary example.

Xbee Sensor

Xbee sensors are designed for a variety of applications, including sensing temperature, humidity, and ambient light. Key features include:

  • Frequency: Operates in the ISM 2.4 GHz band.
  • Data Rate: Offers an RF data rate of approximately 250 Kbps.
  • Range: Provides an indoor coverage of about 133 ft and an outdoor coverage of about 400 ft.
  • Power: Transmits at 1.25mW in normal mode and around 2mW in boost mode.
  • Topologies: Supports mesh, point-to-point, and point-to-multipoint network topologies.

The Xbee sensor can measure:

  • Temperature: From -18°C to +55°C with an accuracy of ±2°C.
  • Humidity: Within a range of 0 to 100% RH with an accuracy of ±3.5% RH.
  • Light: Within a spectral bandwidth range of 360 to 970 nm.

Optical smoke sensors and magnetic sensors are also available based on the Zigbee standard.
