Rainfall Sensor Tipping SEN Rain Bucket Type
This tipping bucket rain gauge is a dependable instrument used for measuring precipitation. Rainfall that enters the 200 mm funnel collector is directed to the tipping bucket assembly. When an incremental amount of precipitation has been collected 0.2 / 0.5 mm the bucket assembly tips and activates a magnetic reed switch. The sample is discharged through the bas of the gauge. a momentary electrical contact is provided for each increment of rainfall. The contact closure is used to operate a data acquisition system. A heating kit has been added at extra cost to the rain gauge to provide capability for measuring snowfall. This rainfall sensor can be easily use with any pulse counter, Data logger / event logger which can use pulse input.

Pollution & Gases Measurement Sensor This is a multi-in-one air quality module sensor. It can accurately measure the concentration of various gases in the air. Raised dust, as one of the main sources of airborne particles, contributes 40% proportion of PM10 composition. It is a remarkable pollution which is very harmful risk for human beings. Accurate monitoring for raised dust outdoor then become necessary to provide the basis for efficient control, which is a basis to mitigate the pollutions
The PWSMini is designed by Dr. Sten L�¶fving is a spin off from our MiniOFS sensor and it is probably the cheapest Present Weather Sensor on the market. And it is very compact - the width is only 68 mm. This little sensor measures 3 important weather parameters. (1) Visibility (2) Rain - the response is fast compared to that from a tipping bucket. The threshold is also lower. (3) Snow - same as for rain - note that a simple tipping bucket sensor does not detect snow in many cases. Besides that two other weather parameters are measured and displayed: Ambient light - the resolution and accuracy is not as good as for special sensors like solarimeters but the information is useful for giving answers to questions like telling if it is cloudy or not or of course if night or day. Temperature - the temp. sensor is located inside the sensor body and the accuracy is therefore not better than about 2 deg C. (But this is in some cases good enough - trends can be seen etc.)
This sensor is used to detect the presence of surface moisture on foliage and calculate the duration of wetness. When moisture is present, the sensor detects an electrical resistance change between the gold-plated elements of the grid. This is displayed by the logger as a value between 0 (dry) and 15 (wet). Sensor Output: Resistance varies from above 3,000,000 ohms when dry to around 1,000 ohms when wet Sensor Range: 0 to 100% of the dew range, frost and freezing conditions will not harm the sensor Response Time: 0 to 100% relative dew within six minutes Output: voltage output (Analog)
MiniOFS is designed by Dr. Sten L�¶fving is used to make direct measurements of visual range. The sensor is sensitive for particles in a zone about 25 cm ahead of the location of the sensor who limit the visibility in the air. These particles are normally the microscopic water particles constituting fog, but they may also be snowflakes, raindrops or air pollutants. But the most indications of low visibility are because of fog or snow. The MiniOFS is probably the cheapest visibility sensor on the market. It is well known that fog causes many accidents in road traffic and elsewhere. You can read about how MiniOFS can reduce serial collisions in fog.
Soil Tension sensor is a solid state electrical resistance sensing device that is used to measure soil water tension. As the tension changes with water content the resistance changes as well. That resistance can be measured using the soil Sensor. The sensor consists of a pair of highly corrosion resistant electrodes that are embedded within a granular matrix. A current is applied to the Sensor to obtain a resistance value. This sensor is designed to be a permanent sensor, placed in the soil to be monitored and â??read as often as necessary with a portable or stationary device. Internally installed gypsum provides some buffering for the effect of salinity levels normally found in irrigated agricultural crops and landscapes.
