SEZO™ EL
Monitoring Noise and Luminosity

SEZO EL 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.

BATTERY POWERED

SEZO EL is powered by lithium batteries with a total capacity of 13000mAh. The use of low power LoRaWAN technology extends battery life up to 5 years of SEZO EL use. Thanks to this, the device can be installed in any place, even in a one that is difficult to access.

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 EL 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 EL to another existing platform used by your company.

MEET SEZO EL

  • SEZO EL monitors environmental parameters such as temperature, humidityatmospheric pressure, light intensity and noise level.
  • Built-in accelerometer and PIR sensors allow detection of human presence within a range of 1 meter from the device.
  • SEZO EL 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 EL 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 EL is battery-powered and the battery life span is up to 5 years.

Use Cases

FACILITY MANAGEMENT

SEZO EL makes refineries and chemical production companies more secure.

Facility managers leverage the SEZO EL 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, as well as acoustic intensity).

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

PUBLIC INSTITUTIONS

SEZO EL makes public institutions more comfortable and more efficient.

Public facilities like libraries, museums or city halls leverage SEZO EL 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 EL makes school a safe and comfortable place for children and staff.

School management leverages SEZO EL to keep track of the noise levels on the school premises to prevent children and staff from being repeatedly exposed to potentially harmful sounds’ volume. SEZO EL allows its users to monitor the temperature on the premises in order to have control of room conditions and ensure optimum and stable working and learning conditions.

The device is battery-powered , and can therefore be used conveniently in various locations. A single battery can last for up to 5 years of constant usage, making the usage hassle-free.

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

INDUSTRIAL PRODUCTION SITES

SEZO EL 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 e.g. sound levels. SEZO EL device is powered by a 13000 mAh battery.

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.
