Evaluation of Inexpensive Dust Sensors for Measuring Respirable Dust in Surface Mines – Field Demonstration
August 6, 2020
2:00–2:30 PM Eastern Daylight Time
This presentation describes work toward the development and deployment of an integrated monitoring and response system for respirable dust in surface mines and support facilities. The proposed system will employ an integrated network of inexpensive wireless dust sensors capable of continuous real-time detection and reporting of respirable dust concentrations. The system would enable rapid response to detected elevations in respirable dust concentrations including dispatch of water trucks to reduce dust on haulage roads, use of water sprays at digging and loading benches, repair of existing control systems, or investigation of previously unidentified sources of exposure. The ability to measure exposure to respirable dust in real-time allows for a proactive control response to what can often be very transient exposure scenarios, for which traditional sampling and analysis approaches are ineffective.
After participating in this webinar, attendees get:
- Introduction to some inexpensive particulate matter (PM) or “dust” sensors
- Description of an integrated network of wireless dust sensors for respirable dust
- Discussion of protocol for low power long range (LoRa) wireless data transmission
- The Things Network (TTN) LoRa and Cloud-Based Data Management (Cayenne)
- Field deployment and testing of wireless dust sensors

What is an ACGIH® Webinar?
ACGIH® is dedicated to providing quality, scientific, educational events. One method of doing this is to offer distance-learning webinars. A webinar, short for Web-based seminar, is a presentation, lecture, or seminar that is transmitted over the Internet. A key feature of a webinar is its interactive elements — the ability to give, receive and discuss information. Webinars are as effective as on-site presentations without the travel expense. This ACGIH® webinar is .5 hours in duration and consists of a live presentation given via the Internet with no option for call in audio.
