SEZO A1L  
Complex Environment Monitoring 

 

SEZO A1L is a compact sensor device, measuring environmental parameters, luminosity, noise level and air quality, with a built-in accelerometer, magnetometer and motion detection. This handy device is suitable both for indoor and outdoor environment monitoring.

MEASURING AIR QUALITY

SEZO A1L provides information on air quality by measuring the levels of PM1, PM2.5 and PM10, which are very harmful to human health and life. The device thus provides information on whether it is safe to be outside.

LORAWAN TECHNOLOGY

It allows the devices to use unlicensed ISM band – which means no subscription fees are required. The devices using LoRaWAN send data either after being triggered by an event (e.g. movement, switching on the light) or based on a fixed schedule (e.g. every 15 minutes).

PLATFORM INTEGRATION

SEZO A1L is integrated with the Orange Live Objects platform, which allow an easy access to the data collected by the device. It is also possible to connect SEZO A1L to another existing platform used by your company.

  • SEZO A1L monitors environmental parameters such as temperature, air pollution (PM), humidity, atmospheric pressure, light intensity and noise level.
  • Built-in accelerometer and PIR sensors allow detection of human presence within a range of 15 meters from the device.
  • SEZO A1L transmits data at the time of an event (e.g. motion detection) or in user-defined intervals. Configuration of the device is performed via USB.
  • SEZO A1L can be used both indoors and outdoors – it operates without any interference at temperatures ranging from -30 to +60°C.
  • LoRaWAN technology enables long-distance data transmission – the distance between the device and the gateway can be up to 10 km.
  • The SEZO A1L device is powered by an external power supply unit with a voltage of 230V, so it can be connected to a common electrical outlet.

Use Cases

FACILITY MANAGEMENT

SEZO A1L makes refineries and chemical production companies more secure.

Facility managers leverage the SEZO A1L device to measure shocks and movements of critical facility components and machinery, thanks to the built-in accelerometer.

The device can be adjusted to clients’ individual needs, involving the measurement of basic environmental parameters, i.e. temperature, humidity, atmospheric pressure and sound levels. The device has an integrated alarm threshold configuration, giving the user the capability to adjust alarm thresholds of all measured parameters (such as temperature, humidity, light, air quality, as well as acoustic intensity).

The device is capable of sending data to the Orange Live Objects platform via LoRaWAN.

PUBLIC INSTITUTIONS

SEZO A1L makes public institutions more comfortable and more efficient.

Public facilities like libraries, museums or city halls leverage SEZO A1L capabilities such as monitoring temperature, humidity, sound level, and illumination to make the space more comfortable and efficient. Thresholds for the measured parameters can be set individually through the build-in alarm threshold configuration.

The integrated accelerometer enables measurement of shocks and/or movements (e.g. of objects such as doors or exhibition pieces) and can potentially decrease response time of facility security (more reliable than CCTV).

The device is capable of sending data to the Orange Live Objects platform via LoRaWAN.

SCHOOLS

SEZO A1L makes schools a safer place for children and staff.

School management levarages SEZO A1L to detect and prevent exposure to floating dust on school yards and parking lots and therefore make schools a safer place for both, children and staff. SEZO A1L measures particulate matter such as PM10, PM2.5, and PM1.

The device is powered via AC 230V power supply, and can therefore be used conveniently in various locations with a common power socket.

The device is capable of sending data via LoRaWAN to the Orange Live Objects platform.

INDUSTRIAL PRODUCTION SITES

SEZO A1L enhances security processes at industrial manufacturing sites.

The device is capable of sending data to the Orange Live Objects platform via LoRaWAN and pulls data from the environment like dust levels (PM1 / PM2.5 / PM10), sound levels. SEZO A1L device is powered by AC230V.

The device has an integrated PIR (infrared) sensor, so it can detect the presence of people (like light detectors). This can be used as an alarm function, individually configured by the user. PIR sensors are commonly used in security alarms and automatic lighting applications.

The device has an alarm threshold configuration for all measured parameters.
