LORD PRODUCT DATASHEET ENV-Link -Mini -LXRS ® Wireless Environmental Sensor Node The LORD MicroStrain® ENV-Link® -Mini -LXRS® is an environmental monitoring node designed to continuously acquire sensor data in outdoor or harsh settings. The ENV-Link® -Mini -LXRS® accomodates a relative humidity/temperature (RHT) sensor, and 3 additional 0-5 VDC sensors. Possibillities include pyranometer (light measurement), soil moisture, leaf wetness, rain gauge, wind speed and direction, water level, barometric pressure, conductivity, strain gauges, thermocouples, etc. Multiple units may be deployed up to 2 kilometers from the wireless gateway, and data is either stored locally or forwarded to a cloud server, providing analysis tools, scripting, alerts, and downloads. Long-life batteries allow long term untended data acquisition. Features & Benefits System Overview High Performance • SensorCloud web based environmental monitoring • Scalable, ultra-long-range wireless sensor network • Lossless data throughput under most operating conditions • Low-power for extended battery life At the heart of MicroStrain® LXRS® Wireless Sensor Networks are WSDA® gateways, which use our exclusive beaconing protocols to synchronize precision timekeepers embedded within each sensor node in the network. The WSDA® also coordinates data collection from all sensor nodes. Users can easily program each node on the scalable network for simultaneous, periodic, or burst mode sampling with our Node Commander® software, which automatically configures network radio communications to maximize the aggregate sample rate. Ease of Integration • Rapidly deployable wireless form factor • Simple integration supported by comprehensive SDK Cost Effective • Reduced cost and rapid time to market for custom applications • Aggressive volume discount schedule Data Access Personal Computer EH-Link® TC-Link® Global Web Access iPad • environmental monitoring • precision agriculture • crop maintenance • ecological research • smart building HVAC monitoring • solar and wind surveying Phones & Tablet WSDA® -1000 ENV-Link™ -Mini SensorCloud® Enterprise Wireless Sensor Network (WSN)

ENV-Link® -Mini -LXRS® Wireless Environmental Monitoring Node Digital Relative Humidity and Temperature Sensor This option is a surface mountable relative humidity and temperature sensor. A unique capacitive sensor element is used for measuring relative humidity while temperature is measured by a band-gap sensor. Both sensors are seamlessly coupled to a 14 bit analog to digital converter and a serial interface circuit. Each is individually calibrated in a precision humidity chamber. The calibration coefficients are programmed into an OTP memory on the chip. These coefficients are used to...

ENV-Link® -Mini -LXRS® Wireless Environmental Monitoring Node Silicon-Cell Photodiode Pyranometer Sensor This silicon-cell pyranometer is calibrated to measure total shortwave radiation. The evaporation of water from soil and the transpiration of water from plant leaves are largely determined by the intensity of shortwave radiation, which is measured in watts per meter squared. This cosine-corrected sensor is designed to maintain its accuracy when radiation comes from low zenith angles. Specifications Cosine response 45º zenith angle: ± 1%, • 75º zenith angle: ± 5% Absolute accuracy custom...

ENV-Link® -Mini -LXRS® Wireless Environmental Monitoring Node Photosynthetic Photon Flux Sensor An innovative blue lens improves the accuracy of these sensors. The pigments in the lens filter incoming light for an improved spectral response. Photosynthesis is driven by the number of photons between 400 and 700 nanometers (nm). This is called the Photosynthetic Photon Flux (PPF) and is measured in μmol/m2/s (micromols of photons per square meter per second). PPF sensors are commonly called quantum sensors because a quantum refers to the amount of energy carried by a photon. Specifications...

ENV-Link® -Mini -LXRS® Wireless Environmental Monitoring Node Leaf Wetness Sensor The optional leaf wetness sensor is standardized, calibrated, and designed to detect wetness (presence and duration) and ice formation right out of the box. No painting, baking, or user calibration required. Each sensor is precisely factory-calibrated to detects tiny amounts of water and ice on the leaf surface. The sensor surface coating is not hydroscopic, eliminating false wetness detection. The sensor’s thin (0.65mm) fiberglass construction closely approximates the heat capacity of a typical leaf, and its...
