Barometric pressure sensors measure fluctuations in the pressure exerted by the atmosphere. The sensors require protection from condensing humidity, precipitation, and water ingress. They are typically housed with the datalogger inside an environmental enclosure. If the enclosure is airtight, the sensor's pressure port must be vented to the atmosphere.

Basic weather sensors measure six parameters: wind speed and direction, precipitation, barometric pressure, temperature, and relative humidity. These compact, multi-function sensors have no moving parts.
-
CDMs - Campbell Scientific, Inc.
Campbell Distributed Modules (CDMs) increase the channel count of dataloggers, add datalogger functionality (such as higher measurement precision or vibrating-wire capability), and improve measurement quality by moving the point of measurement closer to the sensors—all while allowing a network of modules to behave as a single datalogger.

Relay drivers provide power directly to external devices that have modest power requirements. Relay drivers also provide control signals to heavy-duty external relays that, in turn, control power to heavy-duty, high-power equipment, such as ventilation fans, aquacultural aerators, and refrigeration units.

Campbell Scientific offers several types of sensors to measure precipitation: tipping bucket rain gages, siphoning tipping bucket rain gages, heated rain gages, and snowfall adapters. Users often select their precipitation sensors based on the type of precipitation to be measured (rain or snow), as well as the needed orifice diameter, measurement range, and accuracy level.

Present weather sensors use a laser-based technology to measure the size and velocity of water droplets in the air to determine visibility, measure precipitation rate, and identify precipitation type (for example, drizzle, rain, snow, and hail). These sensors are often incorporated in automatic weather stations for road, marine, and airport applications.

DOT600 - Campbell Scientific, Inc.
The DOT600 is a stand-alone product that measures volumetric and gravimetric water content of samples of earthen material in roadbeds and foundations. Portability, along with quick and accurate measurements, make it a valuable tool for evaluating roadbed material both at the construction site and in the soil-test lab.

Campbell Scientific, Inc.
Campbell Scientific offers two types of sensors for snowpack applications: snow water equivalent (SWE) sensors and snow depth sensors. SWE sensors measure the amount of water contained within a snowpack. Snow depth sensors measure the depth of the snowpack.

Data acquisition software is used for a variety of purposes: to support datalogger programming, enable communication between dataloggers and computers or mobile devices, manage data files, and display data in graphical formats. More advanced users can add custom capabilities or interfaces with our software development kits.

Soil heat flux sensors may consist of several thermocouples whose measurements are averaged, a single thermopile, or a single thermopile with a film heater. These sensors measure the rate of energy transferred through a surface. Data regarding the amount of energy stored in soil as a function of time is used in energy-balance and Bowen-ratio flux systems.

Products for stand-alone soil monitoring. Campbell Scientific instruments are used in a wide variety of soil-science applications. Multiple sensors can be networked in hard-wired or wireless systems to create soil-moisture profiles, while portable, hand-held systems can make point measurements to verify irrigation scheduling or to perform site surveys. Campbell soil sensor products are key to agricultural research, irrigation scheduling, forestry, watershed studies, leak detection, slope stability, and many other disciplines.

Soil temperature sensors come in a variety of designs using thermistors, thermocouples, thermocouple wires, and averaging thermocouples. The electrical signals transmitted from the sensors to our dataloggers can be converted to different units of measurement, including °C , °F, and °K. Our dataloggers are also capable of measuring most commercially available soil temperature sensors.

Soil volumetric water content probes (sometimes referred to as soil moisture sensors) measure the water content of soil. These probes can be used to estimate the amount of stored water in a profile or how much irrigation is required to reach a desired amount of water in the soil. These probes can be used for quick measurements or installed for long-term measurements.

Campbell Scientific, Inc.
Campbell Scientific offers soil water potential sensors that measure soil water potential via two methods: heat dissipation or electrical resistance. The sensors determine the energy status of the water in the soil, which describes the force that holds the water in the soil.

The solar radiation sensors that Campbell Scientific offers come in a variety of designs: pyranometers, net radiometers, quantum sensors, and pyrheliometers. These sensors measure various aspects of the energy imparted by the sun on the Earth’s surface. A leveling fixture fitted with a bubble level may be required to accurately install solar radiation sensors.
