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

Your best ally against spring frost<\/h2>\n<\/div><\/div>

Whether it rains, snows, or blows, your frost sensor is out there, measuring what\u2019s happening in your plots.
That\u2019s why we use durable materials<\/strong> \u2014 for lasting accuracy<\/strong>, even after years in the field.<\/p>\n<\/div><\/div>

The Frost Sensor Measurements<\/h3>

Accurate measurements to track frost risk in your fields<\/h4>\n

Placed as close as possible to the buds, in the most frost\u2011prone zones of your farm, the frost sensor measures wet\u2011bulb and dry\u2011bulb temperatures<\/strong> every minute and sends the data to the Weenat app every 5 minutes<\/strong> during spring frost periods.<\/p>\n\n\n\n\n

Wet\u2011bulb temperature probe<\/strong><\/h4>\n

It\u2019s possible to calculate wet\u2011bulb temperature, but such calculation isn\u2019t accurate.
That\u2019s why at Weenat, we prefer to measure it directly<\/strong>.
Our frost sensor is therefore equipped with a high\u2011precision wet\u2011bulb probe<\/strong> (\u00b1\u202f0.15\u202f\u00b0C).<\/p>\n

Water reservoir and wick<\/strong><\/p>\n

A water reservoir and wick<\/strong> keep the probe slightly humid at all times.<\/p>\n

\"\"<\/p>\n

Dry\u2011bulb temperature probe<\/strong><\/h4>\n

The second probe measures unsheltered dry temperature<\/strong>, which accounts for the effects of wind and radiation.<\/p>\n<\/div><\/div>

Data transmission to the Weenat application<\/h3>

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

High quality equipment<\/h3>

Durable battery<\/h4>\n

The Weenat sensor is wireless<\/strong>. Instead, it runs on a high\u2011resistance battery<\/strong> with at least 2 years of autonomy<\/strong>.
Once empty, the battery can be replaced without technician intervention<\/strong>.<\/p>\n

Multi\u2011mount system<\/h4>\n

Install your sensor in your plots, as close to the buds as possible, for reliable and ultra\u2011local measurement.<\/p>\n
