Soil Moisture Logger
CS-SL-SM
- Measures soil volumetric moisture content with ±2.5% accuracy.
- Operates in temperatures ranging from -40 to +50 °C.
- The zone of influence extends 5cm (radius).
- Equipped with a 1m cable.
- Suitable for long-term monitoring of water levels in greenhouses and agricultural farms.
The CS-SL-SM is an affordable soil moisture logging system comprising a logger (CSL-SM2) and a soil moisture sensor (CS-SM2). The CS-SM2 measures the volumetric water content of the soil, while the CSL-SM2 stores the data locally. The CSL-SM2 can be configured using CreDock (interfaces logger with the computer) and CredoWare (freely available user interface software).
The Self-logging Soil Moisture Sensor System (CS-SL-SM) has a small footprint and is designed to suit a wide array of applications such as irrigation scheduling, greenhouse management, watershed characterization, water balance studies, soil respiration, plant disease forecasting, hydrology, and soil health monitoring.
The CS-SM2 sensors are robust, corrosion-free, and made of industry-grade materials to withstand harsh outdoor conditions. They offer accurate (~2.5%) soil moisture measurements as they are rigorously calibrated on a wide range of soils. Additionally, their relatively large sensing zone (~2.5 cm around the sensor) ensures they can reliably address spatial variations in soil moisture content.
To protect the CSL-SM2 logger from the dew and rainwater, a waterproof box has been used to enclose the whole system. Unlike other soil moisture sensors, the sensor of the Self-logging System is not connected to a multiple channel data logger; thus, it reduces the wiring hassles in the field during the sensor networking.
The CS-SL-SM is a hassle-free and outdoor-ready system. The CSL-SM2 logger is housed in a UV-resistant and waterproof enclosure. Its unique “one sensor per logger” concept reduces wiring hassles in a challenging environment. This configuration also reduces the chance of data loss. For example, in a traditional multi-channel setup, if the datalogger fails (e.g., power failure), the user loses data from all sensors, but with the CS-SL-SM, the user loses data from only one sensor.
- Wear-free design and engineered to last long.
- Temperature-corrected measurements ensure high accuracy.
- Uses high frequency (>70 Mhz) to minimize soil salinity and textural effects.
- Small footprint sensor.
- Outdoor-ready compact design.
- Sensor accuracy: ±2.5% typical with most soils (soil solution EC < 10 dS/m). Soil-specific calibration can enhance the accuracy up to ~2%.
- Operating temperature: –40 to +50 °C.
- Maximum sampling rate: 60 s (software programmable to different rate).
- Power requirement: 3 V (CR2450 battery).
- Sensing zone: 5 cm radius (around the probe).
- Wire length: 1 m.
