Disdro is a low maintenance rain gauge.
Disdro is an acoustic sensor: it listens to precipitation and distinguishes rain from hail. Our sensors not only give you the volume of the showers, but also the size of the drops or the hailstones.
Every 5 minutes the sensor sends it's data to the Things Network via LoRaWAN. To get the shown dashboard there is a subscription needed.
The red colour show the larger drops, the green the smaller drops
Hail and rain
The disdro distinguishes a heavy local shower from drizzly rain and hail from rain.
Disdro's acoustic rain gauge does not require regular cleaning and maintenance; it has no holes for insects ;)
DRIPS 2018 - 2019
Digital Rain IoT Platform via Satellite
The Netherlands’ Small and Medium Enterprises Innovation (MIT) program rewarded the consortium of Fleet, FactoryLab and Disdrometrics with a grant to conduct a world-first trial to connect data from irrigation systems on the ground to nanosatellites in orbit. The Digital Rain IoT Platform via satellite (DRIPs) proposal will aim to transform agriculture through real-time tracking of weather and irrigation systems, creating potential cost savings of 10 per cent or more per year, per hectare of land.
DRIPS will create a local sensor network that will communicate with low orbiting nanosatellites though a local gateway. In regions where communication infrastructure is lacking, the system will help crop growers continuously monitor nutrients, temperature, humidity and precipitation on a low bandwidth frequency.
In DRIPS Disdrometrics is developing a sensor that can connect everywhere in the world without having to deal with local providers, it is a one stop shop.
Kenyan farmers 2018 - 2019
Provide Kenyan farmers with better meteorological data to improve crop yields
Water used for the production of food is often related by people to irrigation, but this an incorrect picture. Most grown food is cultivated with rain. With accurate forecasts you can estimate when the best time is to sow or harvest. But if you are going to irrigate, you need to know where the water resources are and whether you can safely use the surface water. That knowledge is often missing.
Kenya is often being seen as example country an at the forefront for other surrounding African countries. If you get ground on the Kenyan market there is a good chance the product will be accepted in those surrounding countries.
With the low-costs rainsensors of Disdrometrics it is possible to get local weather forecast. Kenyan Farmers are provided with better meteorological data to improve crop yields and develop new approaches to precision farming under a changing climate.
Together with our Kenyan partners we want to support farmers to pro-actively manage their farm, using less water while achieving higher yield (up to 26%). With local soil moisture, local rainfall and actual crop water consumption known, irrigation requirements are calculated with a substantially higher local accuracy then was possible before.
We finished the feasibility study in 2018 and are now starting the second stage (2019).
FloodCitiSense 2018 - 2019
FloodCitiSense develops an urban pluvial flood early warning service for, but also by citizens and city authorities. This service will reduce the vulnerability of urban areas and citizens to pluvial floods, which occur when heavy rainfall exceeds the capacity of the urban drainage system.
Due to their fast onset and localized nature, pluvial floods cause significant damage to the urban environment and are challenging to manage. The FloodCitiSense project aims at integrating crowdsourced hydrological data, collaboratively monitored by local stakeholders, including citizens, making use of low-cost sensors and web-based technologies, into a flood early warning system. Citizens in Brussels, Rotterdam and Birmingham will be actively involved in the monitoring of rainfall and pluvial flooding by assembling their own rain sensor that Disdrometrics as partner of FloodCitiSense creates for them.

Myanmar Partners for Water 2017 - 2018
Leapfrogging Delta Management in Myanmar
Due to the need for more smart data measurements and analyses to be able to adequately choose the most sustainable solutions for water and resource management the government of Myanmar is working together with TU Delft and the partners of VPdelta to jointly develop smart ways to collect these data. The project is funded under the Partners for Water program by the Netherlands Enterprise Agency (RVO).
The main aim is to extend the current work in the Bago-Sittaung to the whole Ayeyarwady Delta to test and demonstrate innovative smart information solutions in the Delta and disseminate the results widely. Coalitions are created around specific information products (e.g. rainfall, erosion, subsidence). In each coalition, partners work on innovative monitoring: to combine remote sensing, ground data collection with modelling techniques.
The results of the project will be presented in an online platform to disseminate the products and services to a local and international audience. Throughout the entire project Dutch and Myanmar experts and young professionals will work together (learning-by-doing) and dissemination and training will be organized.
The partners are the Myanmar National Water Resources Committee, Irrigation Technology Center (Bago), Yangon Technological University, Myanmar Maritime University, VPdelta, TU Delft, Disdrometrics, FutureWater, Akvo, SHORE Monitoring & Research, Mobile Water Management, HKV Lijn in Water, SkyGeo, Wavedroid and VanderSat.
Valve control 2017
Too much water in the soil will wash away nutrients. Too little water will harm crop growth.
Monitoring soil moisture allows farmers to make effective irrigation decisions. However, current sensors are wired and not remote, making them unusable to monitor multiple points in outdoor farm fields. For ‘Broere Beregening’ we installed a low-cost, wireless and remote system that controls the valves in the fields of the farmers.
