The solar powered residual chlorine sensor for water quality is an integrated intelligent sensor that integrates LoRa wireless communication, solar self power supply, and high-precision residual chlorine detection. It is designed for water quality safety monitoring in outdoor scenarios without mains power, and can achieve real-time collection, remote wireless transmission, and cloud monitoring of residual chlorine concentration. Widely used in drinking water, swimming pools, sewage treatment, aquaculture and other scenarios, it solves the bottleneck of traditional wiring difficulties, power supply difficulties, and high operation and maintenance costs.
1.core performance
Adopting the membrane covered electrochemical detection technology, with a measurement range of 0-2mg/L, a resolution of 0.001mg/L, an accuracy of ± 3% FS, built-in temperature and pH automatic compensation, strong anti-interference ability, response time<30 seconds, long-term stable operation, and maintenance cycle of up to 3-6 months.
2.Power Supply and Communication
The solar panel is paired with a large capacity lithium battery, MPPT intelligent charging and discharging management, and can last for more than 72 hours on rainy days, truly achieving unmanned operation; Equipped with LoRa wireless module, it has long transmission distance, low power consumption, supports LoRaWAN 1.0.3 protocol, compatible with RS485/Modbus, data can be directly transmitted to cloud platform, and supports threshold alarm and historical traceability.
3.Structure and Protection
The whole machine adopts IP68 waterproof and dustproof design, and the probe uses gold electrodes and anti pollution film, suitable for harsh water environments such as high salt and high humidity; Flexible installation method, supporting immersion, pipeline, and float installation, ready to use, significantly reducing deployment costs.
