# MacSync L Odor X2 LoRaWAN Odor Monitoring Sensor Datasheet
## Product Overview
**MacSync LODS X2 LoRaWAN® Odor Monitoring Sensor** is a high-precision industrial odor monitoring solution designed for continuous real-time NH₃ (Ammonia) and H₂S (Hydrogen Sulfide) concentration monitoring across wastewater treatment plants, sewage infrastructure, industrial facilities, chemical factories, livestock farms, landfills, smart cities, and environmental monitoring deployments.
Built using ultra-low-power electronics and long-range **LoRaWAN® wireless technology**, the sensor enables reliable remote odor monitoring without requiring complex wired infrastructure. The device continuously measures NH₃ and H₂S gas concentrations to help organizations detect odor pollution, monitor hazardous gas exposure, improve worker safety, maintain environmental compliance, and reduce public odor complaints.
The **LoRaWAN Odor Sensor** is engineered for Industrial IoT deployments where long battery life, wide-area coverage, secure wireless communication, and centralized cloud monitoring are critical. It is ideal for STP & WWTP plants, sludge treatment facilities, pumping stations, waste management infrastructure, smart city odor analytics, industrial safety systems, and environmental air-quality monitoring.
With configurable uplink intervals, threshold-based odor alerts, BLE configuration via the **Macnman Maya App**, and seamless integration with LoRaWAN® gateways and cloud IoT platforms, the **MacSync LODS X2** delivers scalable odor analytics for Industry 4.0 and environmental monitoring deployments.
Its rugged industrial enclosure, IP65 protection, low-power battery operation, and AES-encrypted wireless communication make it suitable for harsh indoor and outdoor industrial deployments requiring reliable wireless odor monitoring.
