LW104D Online LoRaWAN Residual Chlorine Sensor | 0-10mg/L Water Quality Monitoring
ZONEWU LoRaWAN Water Quality Residual Chlorine Sensor
Product Features:
This integrated online detection device is equipped with an exclusive three-electrode system to eliminate signal interference from the source, featuring high measurement accuracy (±5% FS error, ±0.05mg/L repeatability error), a 12-month long electrode service life and no need for frequent calibration. It supports three detection ranges of 0-2/0-10(default)/0-20mg/L, is compatible with LoRaWAN 1.0.3 protocol and LoRa TDMA networking, adapts to global frequency bands and supports OTAA Class A/C dual modes, with a flexibly adjustable data reporting cycle of 1-65535s. Adopting industrial-grade hardware, it withstands 0-50℃, pH 4-9 and 0.6Mpa pressure, comes with a 5m customizable cable, DC5.5×2.1mm, TYPE-C and RS485 interfaces, supports local/remote control and online firmware upgrade, and is available for submerged and pipeline installation.
1. Service
We provide full-process technical support including free configuration tool download and remote guidance for network access and debugging, dedicated after-sales fault detection and repair (no self-disassembly recommended), professional electrode maintenance and replacement guidance, and continuous firmware upgrade package and operation support.2. Production Process
It adopts integrated design to optimize signal transmission, precision-manufactured three-electrode system with standard platinum ring or optional gold ring glass electrode, industrial waterproof sealing with NPT3/4 threads, industrial-grade components through aging tests, precision integration of communication and detection modules, and high-toughness anti-oxidation cables and terminals.3. Operation Method
Configure via Windows with CH340 driver and LoRa_config tool by simple steps; install submerged/pipeline with NPT3/4 threads and ensure 30-60L/h water flow; check power/wiring and judge status by LED daily; clean electrodes by pollution type and replace after 12 months; troubleshoot COM port, device connection, firmware upgrade and water quality parameters for abnormal data or malfunctions.

Application:
Tailored to meet the residual chlorine monitoring needs of different water scenarios: It adapts to municipal water supply network endpoints and community secondary water supply tanks, strictly controlling residual chlorine levels in drinking water to safeguard residents' water safety. It suits the daily operations of swimming pools and hot springs, providing real-time monitoring of disinfectant residual chlorine to prevent bacterial growth due to low levels or skin irritation from excessive levels, ensuring recreational water compliance. It is suitable for aquaculture ponds and hatchery ponds, precisely managing residual chlorine concentrations to balance water disinfection and aquatic survival rates, avoiding losses caused by residual chlorine imbalance. It also adapts to industrial circulating water and sewage treatment plants, tracking residual chlorine indicators throughout the process to support compliance in industrial water treatment processes. Whether in civil water purification, commercial water-related applications, or industrial water treatment scenarios, it achieves accurate and efficient residual chlorine monitoring and control.
