Achieve Early Forest Fire Detection by Carbon Dioxide Monitoring with Milesight EM500-CO2 Carbon Dioxide Sensor



Forest fires or wildfires, are an ever-present threat that often daunt us, especially as the worsen climate change and human error in recent decades. They increase both in frequency and scale, and sometimes turn into mega fires, always causing serious threats to the environment and leading to significant loss of lives, wildlife and property. Therefore, tackling such fires in the early stages is super critical to avoid great and irreparable loss.


  • Huge human resources for wildfire detection
  • Difficulty in early-stage forest fire detection
  • Significant loss if not detected in time

Featured Product

EM500-CO2 is designed for measuring CO2, temperature, humidity and barometric pressure in harsh environments and transmitting data using LoRaWAN® technology. With this low power consumption technology, it can work for up to 10 years with 19000 mAh battery, reducing maintenance costs significantly.


It senses the corresponding change in the CO2 (carbon dioxide) level from 400 to 5000ppm, temperature, humidity, and barometric pressure in the early stage of forest fire, then collects data at a minimum interval of 2 minutes or maximum interval of 30 minutes.

Once the data exceeds the preset tolerance limits defined in the alarm threshold, the sensor will report to the Milesight UG67 LoRaWAN® Gateway timely, and Milesight IoT Cloud will get the insightful data from gateway and sends a notification to alert recipients to take crucial actions , thus contributing to avoiding significant loss.



Milesight EM500-CO2 Carbon Dioxide Sensor provides an effective way to detect wildfire in the early stage mainly by carbon dioxide monitoring and assisted by temperature, humidity, and barometric pressure monitoring in real time. Once the wildfire happens, the carbon dioxide concentration level around the environment will increase, exceeding the normal standard. Meanwhile, the surrounding temperature and barometric pressure will rise as well, along with gradually decreasing level of humidity.

At this time, EM500-CO2 which is placed at optimal locations within the forest will detect the abnormal situation sensitively, and transmit the crucial data remotely through Milesight UG67 LoRaWAN® Gateway to Milesight IoT Cloud to recipients to take effective action in time.
