CS-SM2

Soil Moisture Sensor

The CS-SM2 allows user to determine the amount (volume) of water stored in a soil profile or how much irrigation is required to reach a desired amount of water in the soil at a very affordable cost. The sensors are made of industry-grade materials which ensures that they can be used both in industrial applications (for e.g., agriculture) or in research. The sensors are also calibrated with extreme care and tested for a wide range of soils across the globe.

  • Measures volumetric water content of the soil
  • Fast response time (2s)
  • Offers readings directly in volumetric water content
  • Easy installation (small footprint)
  • Water-proof design
  • Should be connected to the CS-DL824 data loggers
  • Operating Temperature: –40°C to +50°C
  • Measurement range: VWC 0% to saturation
  • Accuracy: ±2.5% typical with most soils (soil solution EC < 10 dS/m). Soil-specific calibration can enhance the accuracy
  • Resolution: 12-bit (0.03%)
  • Power Requirement: 3 – 5 VDC

The CS-SM2 can be connected to a cable of maximum 10 m length. The other end of the sensor is connected to a CS-DL824 data logger. Eight CS-SM2 sensors can be connected to a CS-DL824 data logger at the same time which can record volumetric water content data at a maximum of 2s interval. The output of this sensor can also be used in other irrigation controller (relay) systems to determine when and how much to irrigate.

The CS-SM2 is ideal for applications that require accurate soil moisture monitoring at an affordable price. For your application needs, please consult the product manual and application notes.

It is fast and allows easy to set up sensor-logger system. With our CredoWareDLC software (sold separately) you can configure the sampling rate of each sensor. The CredoWareDLC is available for the operating system of your choice (Mac, Windows, and Linux) and very easy to set up. You can use CredoWareDLC to download data from CS-DL824 and visualize them both in graphics and tabular forms. Please see CredoWareDLC software product page for details.

The CS-DL824 uses four AA batteries (lithium for winter and alkaline for summer). The system has three LEDs: one for sensor status, one for logging status, and one for battery. The sensor status LED when blinking green every 30 s indicates that the sensors are working correctly, and when blinking red at a similar interval indicates that at least one of the connected sensors are not working correctly. Similarly, the logging status LED when blinking green every 30 s indicates that the data logger is successfully logging sensor measurements, and when blinking red at a similar interval indicates that the data logger is failing to log at least one sensor measurements. This gives users an excellent idea of what’s going on.

The CS-DL824 also has hardware support to upload your valuable data to the cloud so that you can monitor your data/sensors from the comfort of your office. It is ideal for applications that require environmental monitoring at an affordable price. For your application needs, please consult the product manual and application notes.
