SNiP-SR5
The SNiP-SR5 is a preconfigured 'Sensor Node Integrated Package' for LoRaWAN communication of real-time measurements of solar radiation, for continuous environmental monitoring.
The SNiP-SR5
The SNiP-SR5 integrates 1x AD-NODE and 1x SP-510 Upward-Looking Thermopile Pyranometer Sensor to a site’s unique network, communication and power requirements.
The SP-510 thermopile pyranometer is designed for accurate and stable global shortwave radiation measurement and reflectance. The upward-looking model is cosine-corrected, with directional errors less than 20 W m2 at 80° solar zenith angle. Long-term non-stability, determined from multiple replicate pyranometers in accelerated aging tests and field conditions, is less than 2% per year. The SP-510 combines a blackbody thermopile detector and acrylic diffuser, and is a significant improvement when compared to the spectral response of silicon-cell pyranometers, but keeps the price close to that of silicon-cell pyranometers.

Further parameters can be added to the SNiP without requiring loggers to match each distinct sensor, substantially reducing the cost of getting a fuller picture on the application.
AD-NODE: For High Resolution Analogue & Digital Sensors
The AD-NODE is designed for those requiring precision in their analogue and digital measurements. With a 24-bit ADC, the AD-NODE supports two RTDs, a 0–10V with compressing range and a 4–20mA input. Each of the four dry-contact digital inputs is capable of simultaneously sampling at 1 kHz, with periodic reporting. Settings on the device can be altered remotely via LoRaWAN™ or locally via USB.
