Do you want to know if there are harmful substances in the air of your living room, or are you worried about stench or noise pollution? Then the trade fair gadget from WoTS 2024 will certainly appeal to you. The Environmental Monitor monitors the temperature, humidity, noise and particulate matter in the environment. In this article we will tell you how the measurements are performed and how the data is converted into usable information.<\/p>\n\t\t<\/div>\n\t<\/div>\n<\/div>\n\n

What does the Environmental Monitor measure?
\n<\/strong>As mentioned, the Environmental Monitor measures various parameters. Three sensors are responsible for this. The temperature and moisture content are measured with the WE-Sensor:2525020210002. This sensor, sponsored by W\u00fcrth Elektronik<\/a>, can operate between -40C and +125C and is capable of measuring moisture contents from 0% to 100% rH.<\/p>\n

The ICS43434 then carries out noise measurements. This component, sponsored by Rebound Electronics<\/a>, consists of a MEMS sensor, signal conditioning, an analog-to-digital converter, decimation and anti-aliasing filters, power management and an industry-standard 24-bit I\u00b2S interface. The I\u00b2S interface allows the ICS-43434 to connect directly to digital processors, such as DSPs and microcontrollers, without the need for an audio codec in the system.<\/p>\n<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n<\/div>\n\n\n

The trio of sensors is completed by the Sensirion SGP40, which BMF System Parts<\/a> has been made available for the gadget project. The SGP40 is a digital VOC sensor (volatile organic compounds) that is easy to integrate into air treatment equipment and air quality monitors, such as the Environmental Monitor. The component is a complete sensor system on one chip and features a digital I\u00b2C interface, a temperature-controlled micro hotplate and a humidity-compensated indoor air quality signal. With this total solution, the VOC observations can be made immediately available for analysis, as is done in the Environmental Monitor. And with its low power consumption, this sensor is ideally suited for battery-powered applications.<\/p>\n

How is it measured?
\n<\/strong>To limit energy consumption, the Environment Monitor measures in intervals (so not constantly). Depending on the power consumption and the energy supply, the interval can be made larger or smaller. And with a mains connection, it is even possible to measure continuously.<\/p>\n

In addition, the positioning of the aforementioned sensors is crucial for an accurate measurement. The design must take into account various factors that can influence the perception of a sensor. How we have dealt with these challenges can be read soon in an article about the design of the housing.<\/p>\n

Sending measurement results
\n<\/strong>Carrying out a measurement generates measurement data. The generated measurement data is processed via the processor and converted into a usable observation. The data is sent via the WiFi module (ESP32-C3-WROOM-02U-N4) to the platform to which the Environmental Monitor is connected. To strengthen the signal strength of the monitor, the FBTS35024-SM-ST 2.4Ghz Antenna was used. The door AVE Added Value Electronics<\/a> sponsored antenna is an accessible and easy-to-use component with an SMA connection. The trade fair visitor connects the antenna to the Environmental Monitor himself, as the antenna is connected to the PCB via an adapter plug.<\/p>\n\t\t<\/div>\n\t<\/div>\n<\/div>\n\n

Processing measurement results
\n<\/strong>The received data ends up in a measuring platform where the values can be read. For the gadget application we have chosen to connect to already existing platforms. In a previous interview<\/a> Andries Lohmeijer already told that the gadget is suitable for long-term use and that you can use the device to participate in citizen measurement networks, such as MeetJeStad or the Sensor Community.<\/p>\n

The software is deliberately built in an open source environment so that users can modify and hack it themselves. A gadget user can also choose to only use their own local network. The aim of this is to keep use as accessible as possible. For example, it is already possible to hang the environmental monitor in the kitchen and make observations about air quality based solely on the LED indicators.<\/p>\n<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n<\/div>\n\n\n

Would you also like to get your hands on such a handy Environment Monitor?
\n<\/strong>The gadget will be distributed free of charge in a limited edition of 1,500 pieces at the World of Industry, Technology & Science trade fair, from 24 to 27 September in Jaarbeurs Utrecht. Trade fair visitors pick up the parts of the gadget from the participating stands and assemble it themselves. Register for the fair for free and collect the gadget via the website.<\/a><\/p>\n\t\t<\/div>\n\t<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"featured_media":0,"template":"","branches":[13],"events":[8],"secretariat":[],"categories":[57],"themes_tax":[],"content_types":[],"class_list":["post-49003","news","type-news","status-publish","hentry"],"acf":[],"yoast_head":"\nWoTS Gadget, van meten naar weten!
