Net People Counter & Air Quality Sensor

Main Application 

■ Environmental wellness measurement sensor

Possible Applications

■ Prevention for the concentration of people against Covid
■ Air Quality Monitor, to know when to ventilate the affected areas
■ Alert system for the concentration of people or agents harmful to health in the air
■ Capacity control in spaces through concentration of people and air quality


Indoor air quality is one of the most integral components of well-being. Since we spend most of our time indoors, we need to make sure we breathe healthy air in our home, workplace, and school.Released VOC compounds can stay in your home or space for up to 5 years.

This device is an effective system to control two of the most accurate indicators in the fight against Covid: Concentration of People & Air quality

Now more than ever, clean air is essential. 



Environmental wellness measurement sensor.

We use Wi-Fi and Bluetooth to scan frequencies and to detect mobile devices that are active to determine an approximate concentration of people.

Various Air Quality sensors determine the air quality in the same space, which is related to the concentration of people in that space. These types of devices are highly recommended for COVID control in closed spaces.

This device is autonomous, and does not need any gateway or other system to work, it can also work configured as groups and by zones, allowing a complete analysis of a single space, several spaces in the same building or even several buildings. You can check and view the status of the air quality of your space and the concentration of people from your device, tablet, or any PC with an internet connection through our free dashboard, which allows you to send alerts when any of the values ​​go out of the established safety range.



Dimensions: 60mm x60mm x35mm

Weight: G. W 60gr

Input voltage: +12VDC


  • Wifi: 802.11 b/g/n (802.11n up to 150 Mbps)
  • Bluetooth: Bluetooth v4.2 BR/EDR and BLE specification

Central Processing Unit:

  • CPU speed: 80MHz to 240MHz
  • Program Memory Size: 4MB



Through our visualization portal, you can analyze and see in real time the state of air quality and concentration of people in your spaces.

We can customize the graphics to be more representative for you if you have a large park of sensors that you need to monitor.

Dashboards allow you to generate alerts by Email and other means. You can view a group of devices, or a single device in conversation, these dashboards can be viewed on any screen, tablet, phone or PC so that you can view them from anywhere you need and even show it to the users of your space!


Status Led Indicator


Each sensor has its own personal air quality / concentration status LED indicator, so that at a glance, any user can act without the need to view a dashboard or APP.

Concentration of people

By scanning the Radio frequencies used by mobile devices today, and taking into account that 90% of the population in large cities carry their devices with them at all times, we can determine how many people are within the radius of action of the sensors, and thus determine the number of people who are concentrated in a space.

These Scan frequency provide us, in addition to mobile devices, any other element that emits RF, for this reason we use an intelligent learning algorithm that discriminates the static detected devices, and allows us to discriminate them. We know the brand, its proximity to the sensor and how many times it appears in each scan.

This indicator of concentration of people is one of the most powerful weapons to fight against COVID.

Air Quality Monitor

We use the most advanced air quality sensors, to be able to emit the most important indicators about the air quality: Temperature, Humidity, Pressure, TVOC (Total Volatile Organic Compounds), CO2 (Carbon Dioxide).

The measurements contemplate more than 40 harmful agents for health in the air, the most common being: Formaldehyde, Ethanol, Benzene, Acetone, Toluene, Butanol, Carbon Dioxide…

Easy Setup

Easy installation, easy configuration and seamless integration.These small devices with various housing colors allow them to be integrated into any space.

For its installation, nothing more than a 12v dc power point is needed. For its configuration by means of a simple reset press on the device that generates a Wifi for its configuration, or by means of our Bluetooth configuration APP, you can connect to the device, assign it a zone name, give it a geographical location and the credentials of your Wifi to have your sensor working in a few minutes.
