8-in-1 solar LoRaWAN water quality sensor (pH/COD/dissolved oxygen/ammonia nitrogen/conductivity/turbidity/ORP/temperature)
Solar LoRaWAN Multi Parameter Water Quality Sensor
Product Introduction:
Solar LoRaWAN self-cleaning multi parameter water quality sensor - an outdoor water quality monitoring terminal that integrates solar self powered, LoRaWAN long-distance wireless transmission, automatic cleaning, and multi parameter measurement. It can simultaneously measure dissolved oxygen COD,pH,ORP, Conductivity/salinity, ammonia nitrogen, turbidity, and temperature, supporting up to 8 parameters, truly achieving "one machine for multiple uses". With 0.88W photovoltaic panels and 3400mAh lithium batteries, the battery can last for at least 3 years under the default 30 minute reporting cycle, completely freeing itself from the constraints of mains power and wiring.
Core functions:
1. Simultaneous measurement of eight parameters, covering mainstream water quality indicators
Support optional dissolved oxygen (0-20mg/L, ± 2%), COD (0-500mg/L, ± 5%), pH (0-14, ± 0.1), conductivity (0-200mS/cm, ± 1.5%), ammonia nitrogen (0-1000mg/L), turbidity (0-1000NTU), ORP (± 1500mV), and temperature (± 0.3 ℃) to meet the monitoring needs of multiple scenarios such as surface water, sewage, and drinking water.
2. Automatic cleaning system, significantly reducing maintenance workload
Built in self-cleaning brush can automatically clean the sensor surface at set intervals (6-6000 minutes) and cycles, effectively preventing microbial adhesion, ensuring data accuracy, and extending manual maintenance cycles.
3. Solar energy+LoRaWAN, worry free outdoor network
0.88W photovoltaic panel combined with 3.7V/3400mAh battery, with a battery life of ≥ 3 years (it is not recommended to report the cycle too short). LoRaWAN supports global frequency bands such as CN470/EU868/US915, Class A/C mode, communication distance can reach several kilometers, and data is transmitted directly to the cloud.
4. IP68 fully waterproof, sturdy and durable
The main body of the multi parameter sensor is made of POM+316L material, with a protection level of IP68, a working temperature of 0-40 ℃, a pressure resistance of 0.2MPa, and can operate stably submerged in water for a long time.
