Solar Power Monitoring

Product Summary

The RK200-03 pyranometer sensor measures solar radiation.

Editorial narrative

The RK200-03 pyranometer sensor measures solar radiation. It is suitable to be used to monitor solar activity in solar parks, solar-dependent systems, and others. In order to reduce the ambient temperature effect, a temperature compensation circuit is built into the sensor. The form factor of the Sensor Hub allows for multiple and/or different sensors to be connected at the same time as well as a solar panel, creating a reliable solar-powered solution. This solution is suitable in scenarios where solar energy is preferred/needed. The splitter cable can connect several Sensor Probes and Probe IOs to a single Sensor Hub port to be powered by the solar power source. The distance between the Sensor Hub and Sensor Probe/Probe IO can be extended via the extension cable. Note: Sensor Hub with Sensor Probe IO and connected sensor cannot be powered on batteries. You need to use the included power supply only. The Sensor Hub has two variants based on the communication type: LoRaWAN only and LoRaWAN+NB IoT. SensorHub's NB-IoT module supports two types of LTE (Long-Term Evolution) categories, namely CAT M1 and CAT NB2. CAT M1 offers higher data rates and lower latency, while CAT NB2 provides ultra-low power consumption and greater coverage, making it an ideal choice for devices that operate on batteries and require long-term connectivity. Features Conform to the WMO standard Suitable for harsh environment Low power consumption High sensitivity External DC power supply Solar panel power source (optional) LoRaWAN/NB-IoT communication Parameter Value Spectral range 300~3200nm Range 0~2000W/m2 Sensitivity > 7-14μV W-1 m2 Measuring angle 2π solid angle Response time ≤35s (99%) Cosine correction ≤±7% (solar elevation angle=10° Temperature effect ±2% (-10~+40℃) Stability ±2%/year Operating temperature -40~+80℃ Included in the package: 1 x Sensor Hub 1 x Sensor Probe IO 1 x Pyranometer solar radiation sensor 1 x Mounting kit for Pyranometer solar radiation sensor 1 x Power supply for t
