The SNiP-LUX is a 'Sensor Node Integrated Package' for LoRaWAN communication of real-time measurements of illuminance, for continuous environmental monitoring (including plant light relations).
The SE-100 Photometric Sensor is a self-powered lux sensor that measures Illuminance in the range of 0-200 Klux over a 0 to 200 mV range. Typical applications of photometric sensors include measuring light levels for human vision in offices, sports arenas, hospitals, museums and more.
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.
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.
The sensor features a rugged, aluminium housing that is fully-submersible and is built to withstand harsh conditions. The sensor cable includes an IP68 marine-grade stainless-steel cable connector 30 cm from head to simplify sensor removal and replacement from permanent installations for maintenance and calibration. Typical applications of photometric sensors include measuring light levels for human vision in offices, sports arenas, hospitals, museums and more.
