High-Quality Eco-Friendly Solar-Powered LoRaWAN Nitrite Ion Water Quality Sensor for Water Quality Monitoring
Product Introduction:
LoRaWAN solar water quality nitrite ion sensor is a LoRaWAN wireless sensor designed specifically for outdoor water quality monitoring. It integrates solar self powered, lithium-ion battery energy storage, and highly selective nitrite ion electrodes, truly achieving long-term online monitoring without mains power, network cables, and unmanned monitoring. The nitrite ion selective electrode based on PVC film, combined with Pt1000 automatic temperature compensation, has a measurement range of 0-2 mg/L, a resolution of 0.001 mg/L, and an accuracy of up to ± 5%, effectively addressing the risk of nitrite exceeding standards in industrial wastewater, surface water, drinking water, and aquaculture scenarios. The device is connected to the ion transmitter through an aviation interface, and the data is uploaded to the cloud via the LoRaWAN protocol, making it easy to cover remote water areas and complex terrains.
Core advantages:
Self powered and ultra long battery life: Built in 0.88W solar panel+3.7V/3400mAh lithium-ion battery, default reporting cycle of 30 minutes, battery life ≥ 3 years under normal use, no need for frequent battery replacement or external power supply.
LoRaWAN wide area communication: Following the LoRaWAN 1.0.3 protocol, supporting OTAA network access and Class A/C mode, stable data transmission within the gateway coverage area, without the need for SIM cards or data fees.
High precision anti-interference ion detection: PVC membrane ion selective electrode is used, which has high sensitivity to nitrite (NO ₂⁻), and automatic temperature compensation and algorithm are used to reduce the cross interference of common negative monovalent ions such as CH3 COO ⁻, F ⁻, Cl ⁻, NO3⁻, etc., ensuring reliable measurement.
Intelligent installation and low maintenance: The transmitter must be installed at an angle of more than 15 degrees (inverted or horizontal is prohibited) to avoid bubble attachment; The electrode needs to be activated in tap water for 24 hours for the first use, and should be stored dry and covered with a protective cap if left unused for a long time. Support remote calibration (zero point, slope, temperature), adjustment of reporting cycle, and device restart through downstream commands, truly achieving "forget settings".
Flexible deployment and industrial design: The equipment weighs only 230g, and both the host and electrodes use waterproof connectors (M16-5 core). The electrode has a service life of 1-2 years and is easy to replace; Provide Type-C local configuration interface and toolbox software for easy on-site debugging and firmware upgrades.
