Predicting Frost Events
In 2013, 85% of the peach production in the Mendoza region (Argentina) was lost because of frost. Because less fruit was produced in the region, 600.000 less work days were needed to process the harvest between November 2013 and March 2014, a reduction in work force of 10.600 people. Across the Mendoza region, frost has caused a loss of revenue of 950 million Argentine pesos roughly 100 million USD in the peach business alone.
A frost event happens when the temperature is so low that the crops cannot recover their tissue or internal structure from the effects of water freezing inside or outside the plant. For the peach production, a critical period is when the trees are in bloom and fruit set (Aug./Sept. in Mendoza), during which the temperature needs to be kept above 3° C. Even a few hours below that temperature causes flowers to fall, preventing fruits to grow.
The goal of the project is to predict frost events in peach orchards by using dense monitoring using low-power wireless mesh networking technology. Off-the-shelf commercial solutions are available today which offer >99.999% end-to-end data reliability and a decade of battery lifetime.
We deploy low-power wireless mesh networks of temperature, relative humidity and soil moisture sensors directly into the orchard. We use machine learning and pattern recognition to build a micro-climate predictive model by continuously analyzing the gathered sensor data in real time, and issue early frost warnings. Prof. Diego Dujovne visit in Paris
During the Visit to Paris, Diego Dujovne developed the first version of the firmware for the Peach Orchard nodes. This firmware is aimed to support four SHT-31-D Temperature/Humidity sensors per node, connected to a I2C bus.
Peach demo Runner-Up IEEE SECON 2016 Best Demo Award!
Congrats to Keoma for being the runner-up IEEE SECON 2016 Best Demo Award with Save the Peaches!
First Sensors Arrived !
We finally received the first sensors ! The team in Argentina is starting to test the SHT31 temperature and humidity sensor. The sensor is sold by Adafruit and is integrated into a board: https://www.adafruit.com/products/2857 We will soon be able to measure temperature with a 0.3°C accuracy and relative humidity at…

April Deployment, day 8
15 April 2016, Mendoza, Argentina. It’s alive ! We started the day early to make sure everything worked fine at the end of the day. We were nicely rewarded by a wonderful view of the sunrise above the “pre-cordilleras”. As promised, the INTA team had installed 20 5m poles between…
April Deployment, day 7
14 April 2016, Mendoza, Argentina. Another preparation day! Today we prepared the lasts boxes, bought battery packs, sold battery connectors, checked the motes configurations, improved the range testing scripts and lost a wallet. Great day! The VPN to the INTA local network is now working right and we can access…
April Deployment, day 6
13 April 2016, Mendoza, Argentina. Today was testing day! We went to INTA Junin and met with Javier who nicely spent time with us explaining his work on frost and salt resistances with fruit trees. We performed several connectivity tests, outside and inside the orchards to get more insights about…
April Deployment, day 5
12 April 2016, Mendoza, Argentina. Thomas and Diego left Mendoza yesterday to return to their respective labs. The local team is now following the work, starting by cutting wood in pieces, fixing those pieces onto the boxes and making sure they don’t move. Yes, those motes are being very agitated so…
