Intelligent Sensor Integration: The Key to Effective Home Automation

By Giuliano Zandonà, Global Product Manager, Home Management Solutions, Nice

In the rapidly evolving landscape of home automation, the importance of multifunctional sensors for monitoring home environments cannot be understated. These are among the most utilized solutions in the smart home context, with a single compact and versatile device capable of detecting movement, temperature, humidity, and light intensity. This allows for the optimization of various aspects of home management: for instance, a temperature sensor combined with a light sensor enables automatic and precise climate control. This translates not only to greater comfort but also significant energy savings. For example, the system can automatically adjust blinds to make the most of natural light, thereby reducing the need for artificial lighting and air conditioning.

The use of multifunctional sensors like the BiDi-Multi Sensor also allows for intrusion detection and presence monitoring, enhancing home security. Additionally, temperature control for climate systems combined with humidity monitoring in sensitive areas helps maintain ideal conditions inside the home, preventing issues such as mold growth. Automation of lighting based on detected brightness ensures efficient energy use, while the activation of home automation scenarios upon movement detection creates environments that dynamically adapt to users' needs.

Environmental Monitoring: Technologies and Units of Measure

Sensor technology is continuously evolving, offering precision and reliability in environmental detection. Here is an overview of the main monitored variables:

• Humidity: Measured in percentage of relative humidity (% RH), representing the amount of water vapor in the air.
• Temperature: Measured in degrees Celsius (°C) or Fahrenheit (°F), it is one of the most monitored variables.
• Light Intensity: Crucial in many applications, it is measured in lux (lx). 
• Movement Detection: Fundamental for security and automation, it is measured in various units depending on the sensor type used.

The Innovative BiDi-Multi Sensor: The Evolution of Detection Technology

The BiDi-Multi Sensor is an advanced bidirectional multifunction device for environmental monitoring. At its core is a passive infrared (PIR) motion sensor capable of detecting movement within a range of about 90° up to 6 meters. PIR technology provides reliable and precise detection with adjustable sensitivity through advanced parameters.

To measure temperature and humidity, the sensor uses high-precision electronic components, providing accurate readings every second. Data is sent to the central hub (Yubii Home or Yubii Home Pro) based on set parameters or significant changes. The measurement precision is 0.5°C within the 0-40°C range, with an adjustable change threshold. The integrated light sensor measures ambient light intensity within a range of 0 to 32767 lux, with values sent at regular intervals or upon significant changes. It is possible to set a change threshold.

An integrated accelerometer detects tampering attempts, immediately sending an alert to the control hub. Wireless communication occurs via a 433.92 MHz radio transmitter with rolling code technology to ensure maximum security.

Configuration and Customization

Through the central hub interface (Yubii Home or Yubii Home Pro), numerous parameters can be adjusted to tailor the sensor's operation to personal needs:

• Detection range for movement 
• Sensitivity and response times
• Notification thresholds
• Data transmission intervals
• Daytime/nighttime operating modes

Installation Versatility

The BiDi-Multi Sensor is designed for quick and flexible installation. It can be wall-mounted or placed in a corner with a recommended maximum height of 2 meters. Battery-powered with an estimated life of 2 years, it is entirely wireless.
