Meteorology Sensors

Weather conditions are often an integral element in water resource and irrigation management applications. Weather parameters are frequently used in understanding and modelling environmental applications that are dependent on water resources. Stevens provides top quality and industry leading weather sensors that are easily deployed into an integrated environmental monitoring and control system.

The Tipping Bucket Rain Gage is a WMO recognized standard for measuring precipitation in remote, unattended locations designed with a siphon system for improved accuracy, especially during high rainfall events.

We also offer additional rain gages for larger catch area and all-season use.


The Met One Ultrasonic Wind Direction & Speed sensor is highly accurate with no moving parts, which eliminates required maintenance common to mechanical sensors. This 16-point wind tunnel calibrating sensor provides digital and analog outputs. Available with a heated option.

We also offer the R.M. Young 05103 mechanical wind sensor.

Solar Radiation

The Apogee SP-212 pyranometer is designed for field measurement of global solar radiation in agricultural, meteorological, and solar energy studies. In clear unobstructed daylight conditions, the SP-212 compares favorably with first-class thermopile-type pyranometers but is priced at a fraction of the cost.

We also offer the Li-Cor Li-200 pyrometer.

Air Temperature / Humidity

The Vaisala Humicap® HMP155 provides reliable humidity and temperature measurement with excellent stability, and withstands harsh environments. The probe structure is solid and the sensor is protected with a sintered teflon filter, which gives maximum protection against liquid water, dust, and dirt.

We also offer other additional sensors for measuring humidity and temperature, including Stevens own Smart Temp Temperature Sensor.

A solar radiation shield will protect a sensor from direct sunlight. It's shaped to allow natural air convection around the probe so that the air being measured inside the shield is an accurate representation of the outside air.

Barometric Pressure

Barometric pressure sensors convert absolute atmospheric pressure into a linear, proportional voltage, which may be used in any meteorological program. The Met One 092 barometric pressure sensor brings in modern digital computer technology. An on-board CPU scales pressure measurements, provides temperature compensation and controls communications output.

All-in-One Multiparameter

The Lufft WS-800 is a complete, high performance weather sensor with a fully integrated design with ventilated radiation protection. It's also the first and only all-in-one compact weather sensor with lightning detection.

It measures air temperature, relative humidity, precipitation intensity, precipitation type, precipitation quantity, solar radiation, lightning detection, air pressure, wind direction and wind speed. One external temperature sensor is connectable.

We also offer the Lufft WS-500, an all-in-one compact weather sensor combining 5 measurement parameters (no lightning detection).


The Novalynx Class A Evaporation Pan is a standard National Weather Service Class A type for measurement of water evaporation. It is normally installed on a wooden platform set on the ground in a grassy location. The pan is filled with water and exposed to represent an open body of water. The pan is filled to within 2.5 inches of the top of the pan. The evaporation rate can be measured by manual readings or with an analog output evaporation gauge.
