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 internally calibrate the signals from the sensors.
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.
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.
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 overall radiation balance closely matches that of a healthy leaf.
Soil Moisture Probe Sensor
The optional soil moisture probe enables low cost monitoring of volumetric water content (VWC) by measuring the dielectric constant of the media using capacitance/frequency domain technology. Its 70 MHz frequency minimizes salinity and textural effects, making this sensor accurate in almost any soil or soilless media. Factory calibrations are included for mineral soils, potting soils, rockwool, and perlite. This handy little sensor is easy to install in the field and can also be used in nursery pots. The robust design makes it easy to push directly into undisturbed soil to ensure good accuracy. It consumes only 10 mA of power and operates over a wide temperature range.
Sensor Cable
The optional sensor cable provides an off-the-shelf and easy solution to connect your specific sensor to the ENV-Link™-Mini-LXRS™.
