Pinot noir grapes at Longoria’s Fe Ciega Vineyard monitored by a Valarm remote environmental monitoring box.


One of Valarm’s main uses is remote environmental monitoring and you can get your own Valarm remote environmental monitoring box at Valarm is an affordable tool for remotely monitoring any environment such as a farm, pipes in your basement, a room full of computer servers, water levels and flood alerts, light levels and intruder alerts, and the air quality (CO2 and volatile organic compounds, VOCs) in schoolrooms and business meeting rooms.

In March 2013 we deployed a solar powered Valarm unit to monitor the local climate of the Fe Ciega vineyard site of Longoria wines in Santa Barbara County, California. We built a waterproof box to contain our hardware and attached it to a south-facing fence. Inside the box is the Valarm Pro app installed on a Sony Xperia U ST25i, a beefy lithium-ion battery, a solar/lithium-ion charge controller, and a tiny USB hub for attaching multiple sensors, e.g., the Yoctopuce Yocto-Meteo sensor which gathers temperature, humidity, and barometric pressure data.

Monitoring the environment is critical for agriculture, especially remote farms and vineyards so managers know the exact conditions of the micro-climate of their crops. By analyzing temperature and humidity trends, irrigation and other adjustments can be made to maximize crop yield and protect crops from freezes, or climate-affected pests such as mildew. Below is an example from showing five days of temperature and humidity values collected by Valarm at the vineyard.



Monitor remote environments: Valarm weather data collected at Longoria’s Fe Ciega vineyard


Compare this with the general weather data for the nearest city, Lompoc:


While the low temperature for the nearby city of Lompoc was reported as 45° F, the actual overnight low temperature on the vineyard was 34° F. The Valarm app tells you what’s really happening in a remote environment.
