ROBUST. ACCURATE. MAINTAINABLE.<\/p>\n<\/div><\/div>

The probe that naturally flows to control your irrigation<\/h2>\n<\/div><\/div>

More than a promise, it's obvious: the Weenat capacitive probe will be at your side in the field. Tomorrow and forever.<\/p>\n

So we've planned for sturdy materials, capable of withstanding the worst weather conditions.<\/p>\n

For accuracy that lasts, even after years.<\/p>\n<\/div><\/div>

Capacitive Probe Measurements<\/h3>

Two depths<\/h4>\n

The probes come in 2 sizes (30cm | 60 cm). To measure the water status of your soils at different depths.<\/p>\n\n\n\n\n\n

Soil moisture sensors<\/h4>\n

Several ultra-sensitive sensors (one every 10 cm) are placed on the Weenat probe to measure soil water content (\u00b1 1.5%). The magnetic field of these sensors is disturbed by water, but not by air, which allows your probe to determine the amount of water present in the soil.<\/p>\n

Temperature probe<\/h4>\n

The Weenat capacitive probe is equipped with sensors (one every 10 cm) to evaluate soil temperature (\u00b1 0.5 \u00b0C).<\/p>\n<\/div><\/div>

Sending data to the Weenat application<\/h3>

Sensor data is transmitted in near real-time via low-speed Sigfox, LoRa or LTE-M NB-IoT (4G \/ 5G) networks, which are energy-efficient.<\/p>\n<\/div><\/div>

High-quality equipment<\/h3>

Resistant battery<\/h4>\n

Like all Weenat sensors, the Weenat capacitive probe works wirelessly. Instead, you'll find an ultra-resistant battery, with a minimum autonomy of 2 years. When empty, your battery can be changed without the intervention of a technician.<\/p>\n

Resin PVC tube<\/h4>\n

PVC is a solid and lightweight material. It resists humidity, wind, cold, ultraviolet rays. And even flames. So rest assured that your probe will always be in top condition, even in 50 years.<\/p>\n

What are the weather parameters measured by the capacitive probe?<\/h3>

The Weenat capacitive probe measures volumetric water content \u2013 that is, the amount of liquid water contained in a soil sample. This measurement is taken every 10 centimeters, allowing you to monitor the humidity of your different horizons. Thus, you can easily assess the impact of rain or irrigation on your soil. The probe also measures your soil temperature. Again, this measurement is taken every 10 cm.<\/p>\n

If you want to monitor other agro-weather parameters on your plots, the capacitive probe can be coupled with one or more other Weenat sensors, such as the rain gauge, anemometer, tensiometers, frost sensor or leaf wetness sensor.<\/p>\n<\/div><\/div>
