Review: Djinn Sensor

The ingenuity and the inventiveness led DJINN Sensor — a Belarus company — to build an Air Quality monitor a bit different from the rest in the market.

Software-wise and hardware-wise the device offers some engaging features like solar panel case in order to harvest energy from the Sun and Productivity Current and Index analytics, to name a few. Let’s take a closer look at the AQ Monitor.

  • Formaldehyde HCHO   —   Winsen ​ZE08-CH2O Optional

 

Analytics

All environmental parameters, like light, air quality, temperature, etc have a significant impact on the processes of mental activity and physical activity in a room. Various scientific studies confirm and support that the impacts are immediate and accumulative.

Below we can see a basic graphic representation of some of the parameters that all devices are able to generate nowadays and they help us understand thousands of disparate data.

DJINN Sensor’s dashboard goes a step further and is able to generate deeper analytics like the Comfort/Productivity Index and Health Risks. Successful visualisation allows you to digest the data in a more appropriate way and in a much shorter time.

This is achieved thanks to sophisticated algorithms (mathematical models) and hard work the team behind DJINN had put into the device.

The main aim here is to increase productivity and reduce health risks for the employees. Below you can see some interesting findings when employees had the follow parameters adjusted for them. They are also able to forecast the risks of productivity and changes in productivity.

Productivity analytics

We see that simply measuring and showing data is not enough today, they are developing medical diagnostic services, business values, integration into smart office systems in conjunction with intelligent assistants such as Alexa and Google Home.

Communication

The device comes with a SIMCom SIM7000E GSM, NB-IoT modem, Wi-Fi 802.11 b/g/n and Bluetooth: v4.2 BR/EDR – BLE. There is an optional configuration for LoraWAN. Another great feature of the device is the Nokia IMPACT which offers a secure, standardized, simplified NB-IoT platform.

Energy

The device is equipped with 4 or 5 solar panels depending which version you are you going to choose with or without a display. The Solar Panels create a fully autonomous device when the device takes 4 measurements every hour. Also, you can use a micro-USB cable to charge the 6000mA Li-Pol battery in case the sunlight doesn’t reach the device. In this case the device can hold a charge up to 5 days. The device uses the Maximum Power Point Tracking algorithm which is included in charge controllers for extracting maximum available power from solar panel module under certain conditions. You can read more details on how the device manage Energy in the datasheet.

Sensors

Nothing unique here, the monitor has some of the wide available sensors that we all have seen and trust like the Carbon Dioxide CO2 from Telaire or the temperature/ humidity/ pressure sensor from BOSCH among a few. Finally, the device is using a Light sensor too from Texas Instruments which is a nice addition but light sensors are a bit tricky especially if you don’t place them in the right place to capture available light from various angles and without a shadow cast on them.

Visualisation

I love e-ink displays, they bring a joy to my eyes and they don’t distract you because they don’t emit light plus they save a ton of energy, so you can choose a device with a 4.2inch in diagonal display and with a resolution of 400×300 pixels.

LCD

Also, you can access the measurements from the web page at http://dashboards.djinnsensor.com/. The company uses ThingSpeak which is an IoT analytics platform service that allows you to aggregate, visualize, and analyze live data streams in the cloud. ThingsBoard Dashboard

Finally, you can export your dashboard data to your computer for further personal analysis with a click of a button in a .json file format.

DIY KIT

For those whose hands itch to make their own design of an environmental sensor, there is available a basic Eco Sensor Kit. Here you can see a photo of a Lego Robot – DJINN with the Eco Sensor Kit integrated but apart from a children’s design it could be integrated into refrigerators, lamps, photo frames, furniture, vehicles, you name it.

Conclusion

DJINN is designed with one thing in mind, how companies can monitor and improve the working environment for a mutual benefit of the employees and the employers. Employees who will become more productive and more healthy and as a result, they will be able to enjoy their spare time outside work as well. Price-wise the monitor is accessible and even more accessible without the display for both companies and individuals, at the end of the day you will have to log-into your dashboard and get a good idea of what changes you have to make to maximize your potentiality.

  1. Hi there! Your analysis has been superior and so helpful! Thank you!
    My son & I lived in a home with mycotoxins & commercial pesticides (from adjacent golf course) for over a decade. Now, with lung damage etc. we are incredibly sensitive to indoor air pollution. I’m looking for 1-2 IAQ monitors.

    I’m in the US and having trouble getting responses from some of these companies. Specifically been on the Djinn website (used your link). No response to emails and IM. I clicked on ORDER NOW on their website as well as CONTACT US and followed their steps but nothing.

    Any contact info you can share. Other than what’s on their website.

    Thanks!
