LoRaWAN Forest Fire Detection Solution【Case Study Available】

LoRaWAN Forest Fire Detection Solution【Case Study Available】

Early detection of forest fires, mountain fires, and wildfires! Centralized remote monitoring of CO2 concentration, temperature, and humidity via smartphone or PC, with built-in battery for low maintenance costs.

LoRaWAN Wireless Communication Features ■ Low Power Consumption: The power consumption varies slightly depending on the end device, but it has a fast transmission and reception speed, and consumes less power compared to other communication standards, which helps reduce maintenance frequency. Additionally, it consumes so little power that two-way communication can be achieved with just one button battery, and it is said that such batteries can operate continuously for over 10 years in some cases. ■ Long-Distance Communication: The range of the 800MHz band used by smartphones (3G and later) is said to be about 2 to 5 km, but with LoRaWAN, communication is possible over a distance of about 10 km, more than double that. In places with few obstacles, communication over distances greater than 10 km is possible, but for practical use, it is advisable to assume about 3 to 5 km in urban areas and about 1 km in indoor environments with obstacles. ■ High Noise Resistance: The 920MHz band used by LoRaWAN is less prone to interference from other wireless networks, even in environments where they exist, which helps reduce communication latency and allows for stable communication. Therefore, it can be safely utilized in factory facilities and indoors.

"MORITO" for heatstroke and ventilation measures in factories and warehouses.

"MORITO" for heatstroke and ventilation measures in factories and warehouses.

Visualize a safe and comfortable environment in the workplace or office with temperature, humidity, and CO2 sensors!

In workplace environments such as food factories, warehouses, and refrigeration facilities, the management of "temperature," "humidity," and "ventilation" is directly linked to the health and safety of employees. The temperature and humidity/CO₂ sensors provided by Harmony address the following challenges: - Maintaining quality and hygiene through temperature and humidity management in food factories and warehouses. - Visualizing the WBGT (Wet Bulb Globe Temperature) to assess the risk of heatstroke during the summer in advance. - Monitoring humidity to prevent excessive dryness and the spread of viruses in winter. - Supporting measures against "stale" air and "oxygen deficiency" by visualizing CO₂ levels in homes and offices. - Enabling immediate response to abnormalities with real-time monitoring and notification functions. Utilizing sensors for "visualization" leads to the prevention of health hazards and improvement of the working environment. Why not implement safety measures that can be easily installed and started immediately? *For more details, please download the catalog or contact us.*
