snoop1130 Posted January 28, 2020 Share Posted January 28, 2020 EIT now teaches how to make a DIY air particle counter CHIANG MAI(NNT) - The Engineering Institute of Thailand (EIT) has opened free workshops for those interested, and will be installing these devices in remote communities and schools in Chiang Mai. This DIY air particle counter can measure PM 1.0, PM 2.5, and PM 10, as well as temperature and humidity. The device uses laser technology from scattered light inside the sensor to count the particles, which is a reliable industry standard. Some 50 people participated in a workshop, held by the EIT, where they learnt about the materials, parts, assembly, software installation and data readings from the monitor. The EIT President Thanes Weerasiri said this device only costs 1,500-2,000 baht to build, and produces air particle readings at an accuracy comparable to the devices used by the Pollution Control Department. The EIT will be delivering 50 of these devices to the Yak Khao association, founded by educational institutes, government agencies, private firms and volunteers. The association will then install them in remote schools and communities in Chiang Mai province, in an attempt to help fight air pollution in the northern region. -- © Copyright NNT 2020-01-28 Follow Thaivisa on LINE for breaking Thailand news and visa info Link to comment Share on other sites More sharing options...

yokat Posted January 29, 2020 Share Posted January 29, 2020 People already have fans, they should advertise the diy filters that consist in strapping a hepa filter to a fan.

mwbrown Posted January 29, 2020 Share Posted January 29, 2020 (edited) I'm building my own now, with a Sharp PM2.5 sensor module and an ESP32 microcontroller and a custom circuit board. Total cost is about 480 baht, almost half the cost is the LiPo battery. Parts are slow coming from China due to New Year's shutdowns.

Prairieboy Posted January 30, 2020 Share Posted January 30, 2020 And how does knowing the particle count protect you from the adverse effects? 1 Link to comment Share on other sites More sharing options...
