Open-source dendrometer — measuring water stress through the plant
Development of a connected dendrometer within the OSFARM open-source collective: trunk micro-variation as a direct indicator of water stress.
Design office & custom builds
Your sensor doesn’t exist? We build it.
Behind the FURGO sensors is a complete electronics design office, based in Montpellier. It also designs for others: technical institutes, companies, local authorities, farmers with a problem no off-the-shelf product solves. From specification to the enclosure installed in the field, everything is done here.
Our philosophy: fast and low-tech, getting the best out of existing open-source building blocks rather than reinventing every component. Where a classic design office targets high-volume consumer runs, we have the agility of the small agricultural series — 10 to 500 units, rugged, repairable, fairly priced.
The workshop’s capabilities
- Electronics PCBs up to 4 layers, SMD
- Connectivity LoRaWAN, GSM/NB-IoT, BLE, RTK
- Mechanics 3D printing, laser cutting, CNC milling, metal
- Software Firmware, platform, mobile apps
- Production Prototype → small series (10-500 u.)
- Philosophy Open source, repairable, low-tech
These capabilities combine our in-house workshop and two partner venues in Montpellier: the Web5 FabLab and the AgroFablab of Institut Agro — enough to go from the morning’s prototype to the afternoon’s machined part.

Projects out of the workshop
FGNode — a generic measurement node developed with INRAE
The FGNode is a generic, open-source LoRaWAN measurement node developed with INRAE: one board, multiple sensors, to instrument scientific field trials.
SoilWatch: a white-label probe monitoring app for OMAG
FURGO developed SoilWatch, the white-label mobile app that lets OMAG’s customers check their capacitive soil-moisture probes.
Débitdouille: industrialising a spraying sensor born at the Mobilab AgroTIC
FURGO industrialises the Débitdouille, a low-tech flow and pressure sensor for sprayers from the Mobilab project (AgroTIC, CA34, Occitanum), pre-assembled at €220 excl. VAT.
Wine cellar temperature monitoring at the Mas Numérique (Institut Agro Montpellier)
Instrumenting the Mas Numérique wine cellar: FURGO temperature sensors on winemaking and storage, with alerts whenever readings drift.
Air quality sensor: design and use
Design and build of a fine-particle sensor around the PMS5003 module, chosen for its laser particle counting and active fan-driven sampling.
VVTrap: a selective Asian hornet trap, from the workshop to online sales
A selective trap against the Asian hornet, designed and built by the FURGO workshop: from 3D printing to plastic moulding, through to sales on vvtrap.com and Amazon.
LoRaWAN-connected linear actuator: design and testing
Design of a 12 V electric linear actuator remotely controlled over LoRaWAN: electronics, 3D-printed housing, lab tests then testing in outdoor conditions.
