Monitoring environmental air pollution with the Arduino MKR WAN 1300
December eighth, 2022—
The scourge of air air pollution claims a number of million lives globally every year, with industrial processes and power manufacturing accounting for a lot of it. Due to its dangerous nature, governments typically arrange air high quality monitoring stations, though they need to cowl giant areas and yield low decision information. To watch the air high quality of a neighboring ecological reserve, Guillermo Perez Guillen created a small, portable toolkit that may document information from virtually wherever and ship it to the cloud.
Guillen’s system depends on two Arduino MKR WAN 1300 boards, which talk with one another over the LoRaWAN long-range community, together with a Nano 33 IoT for sending the acquired information to an online API endpoint over WiFi. The transmitting MKR WAN 1300 is linked to a set of sensors that measure temperature, humidity, carbon dioxide, carbon monoxide, and unstable natural compounds (VOCs) within the air. Then, at preset intervals, every sensor is learn and the ensuing measurements are despatched to an awaiting receiver MKR WAN 1300 board.
As soon as the information packets have arrived, they’re decoded and displayed on an connected 20×4 character LCD, in addition to being despatched over UART to a Nano 33 IoT. From right here, values are written to a Thingspeak channel to allow them to be tracked over time. Extra details about this mission might be discovered on Instructables.
