In water quality monitoring projects in the wild or remote areas, power supply and communication are often the biggest deployment challenges. Our solar powered water quality potassium ion sensor deeply integrates efficient solar power supply system with LoRaWAN wireless transmission technology, providing a truly wiring free and self-sustaining intelligent sensing solution for monitoring potassium ion (K ⁺) concentration. Suitable for agricultural irrigation, aquaculture, surface water monitoring, and soil nutrient analysis scenarios, it helps you continuously and stably obtain potassium ion data without relying on mains electricity.
Core advantages:
1. Solar self powered, continuous operation without external power supply
The top of the sensor integrates a monocrystalline silicon solar panel and a low-power management circuit, paired with a built-in rechargeable battery. Under conditions of sufficient daily sunlight, the equipment can operate 24/7 and continue sailing for more than 7 days on rainy days. No need to lay power cables, significantly reducing installation costs.
2. LoRaWAN remote transmission, data goes directly to the cloud
Adopting the standard LoRaWAN protocol (supporting global frequency bands such as CN470, EU868, US915, etc.), Class A/C mode is optional, and the default reporting period is adjustable. Even in river valleys, farmland, or aquaculture ponds without 4G signals, real-time data such as potassium ion concentration and temperature can be uploaded to the cloud platform through the gateway.
3. High selectivity potassium ion electrode with strong anti-interference ability
The sensor adopts PVC membrane ion selective electrode, with a range of 0-1000 mg/L (customizable), a resolution of 0.01 mg/L, and automatic temperature compensation (Pt1000). Effectively reduce the cross interference of coexisting ions such as NH ₄⁺ and Na ⁺, ensuring the authenticity and reliability of the data.
