L&M Instruments supplies highly-integrated, multi-sensor Internet-of-Things (IoT) environmental monitors for use across several industries and applications including Collections Management. Our Iris line of IoT sensors pack several environmental sensors into one unit: Temperature, Relative Humidity, Spectral Power Distribution (350-800nm), Color Temperature (CCT), Illuminance (Lux or Fc), Flicker (Percent, Index, and Freq), Stroboscopic Visibility Measure (SVM), Circadian/Melanopic Lux, and Motion Detection. The Iris is a fraction of the cost of monitoring these variables with traditional means, all viewed within a single cloud-based dashboard. Real-Time viewing and Alerts provide flexible monitoring scenarios. Power options include battery operation for weeks of monitoring in spaces where AC power is not available. The Iris sensors are a valuable and flexible tool for both front-of-house and back-of-house monitoring applications including management of passive care techniques.
