    Where are Weenat sensors designed?

    Designed and developed in France, Weenat’s sensors are assembled in the Nantes region, west France, by an adapted business that employs over 80% workers with disabilities. From the design of the sensor to data collection via integrating decision support tools, Weenat controls the whole value chain of its production.

    Do I have to buy a sensor to be able to use the Weenat app?

    The Weenat app can be used without buying a sensor. To benefit from hyperlocal agro-weather data, you can join a local connected weather network near you. You will then have access to data from all the weather stations on the network without having to invest in your own equipment.

    You also have access to more than 8 agro-meteorological parameters on your plots, without needing a sensor, thanks to our spatialized weather technology: Weather Vision. Weather Vision is available via a Weenat Expert subscription package.

    With our basic plan Weenat Essential, the app also allows you free and time-unlimited access to data from a virtual weather station. So you can get the weather on your plots in real time. Even without sensors!

    > See all Weenat app subscription packages.

    How do you set up Weenat agro-weather sensors?

    Weenat sensors are delivered ready to use with a setup guide. You can also find advice and tutorials in the Setting up sensors and accessories window in the Help section in the app.
    Also consider the setup location for your sensor. For a rain gauge, for example, make sure to choose a flat, open space. Avoid closeness to walls, buildings, trees or any other obstacle that might cover the rain gauge. Ideally, the distance between the rain gauge and any obstacle should be more than four times the height of the obstacle.

    Do my sensors need maintenance?

    Sensor maintenance is essential to guarantee the long-term accuracy and quality of measurements. A few simple actions are enough. To learn more, go to the Weenat app, then click on the Help section. There you will find a sub-section Sensor maintenance with extensive advice and video tutorials explaining how to maintain your equipment.

    How long does a Weenat agro-weather sensor’s battery last?

    The agricultural sensors developed by Weenat have an operating life of 3 to 5 years and are equipped with a replaceable battery.

    How does the agro-weather sensor communicate with the app?

    Sensors transmit data using low-frequency Sigfox and LoRa networks. This technology allows information to be transmitted over long distances without using SIM cards or Wi-Fi. It also uses much less energy than a standard mobile network such as 4G.

    Why link a Weenat sensor to your decision support tools?

    You can use some DSTs without connecting them to a sensor on your plots. But the quality of a DST’s results depends on the accuracy of the agro-meteorological data fed into the algorithm.
    Connecting one or more Weenat sensors to your decision support tools lets you supply them with hyperlocal, real-time measurements. The models’ recommendations will then be more reliable, more accurate and better adapted to conditions on your plots.

    Are the sensors geolocated?

    All our sensors for farmers are equipped with a GPS chip allowing them to be easily located.
