German IoT startup Dryad wants to help prevent forest fires
A German setup wants to use IoT sensors and a wireless-mesh network to discover forest fires within 10 minutes to an hour of when they set as opposed to the hours or even days it can take using running methods based on thermal imaging_ satellite surveillance and ethnical smoke spotters.
Dryad Networks is developing sensors to discover gases associated with forest fires and engineering how to network them using LoRaWAN and other wireless technologies so the data they gather can be analyzed in the companys cloud.
The sensors are best located almost 10 feet off the ground in trees_ secured by screws_ making it more hard for nation or wildlife to derange them and ensuring they wont be obscured by grass or fallen leaves_ according to founder and CEO Carsten Brinkschulte_ a habitue of Apple and SAP.

Each artifice is equipped with a LoRaWAN modem_ which communicates with a mesh gateway. Each gateway can feel all the sensors in a six- to seven-mile radius if they are spaced as Dryad recommends--roughly one per 2.5 acres.
In turn_ the mesh gateways send the data they gather--also via LoRaWAN-- to limit gateways that pass it up to the cloud via fixed wireless_ LTE or even satellite_ depending on the area.
One gain the gas sensors have over indoor smoke discoverors is that they can discover fires even if they are upwind of the fire itself owing some of the gases that that the sensors look for discursive in all directions_ the company says.
The sensors are designed to be set-and-forget_ with no livelihood required over their roughly 15-year life cycle. A key design importance was the use of on-artifice solar charging in union with supercapacitor battery technology that doesnt pose the possible fire risk of lithium-ion cells. “We dont want to fetch lithium ion into a forest_” said Brinkschulte.
To form the wireless mesh_ Dryad built a proprietary extension on open-source LoRaWAN software_ but it also granted an open API so others can make sensors able to connect to the network of gateways. Brinkschulte said third-party dampness sensors_ for sample_ could be incorporated in the mix of sensors to better prophesy fire risk in a given area.
The number of limit gateways required would depend on the number of sensors but also on the need for network resiliency. “So perhaps youve got 100_000 sensors_ that would need separate limit gateways to load weigh_” said Brinkschulte. “That resources not all the sensors are connecting through the same locate_ and also helps with redundancy.”
The number of sensors required can be kept to a minimum by deploying them mainly in areas close to ethnical qualification since almost nine in 10 forest fires are caused by ethnical agility_ he said. “The idea isnt to blanket an whole forest_” he said. “Deployed along roads_ pathways_ campsites and faculty lines…we should be able to take 80% of fires.”
Sensors cost almost $40_ but Brinkschulte said he expects that to drop dramatically once equipment enters mass origination next year.
The company says it has letters of intent from nine German companies and a big forestry agency in Africa that wants to use the technology to help defend its resources and also earn carbon-credit certificates.
Helping to decrease ecommissions is a major part of Dryads commission_ according to Brinkschulte. “[W]e want to be a gainful technology company_ but we also want to have an contact_” he said. “The intention is to help defend the bigst forthcoming we have_ which is the forest_ and unfortunately_ were losing a lot of it each year. Forest fires_ globally_ are responsible for almost 20% of [carbon dioxide ecommissions]--thats almost as much as commerce from cars and ships.”
