What Sendot Research B.v. does

Sendot Research B.V. is a Dutch optical sensor technology company founded in 2015 and headquartered in Houten, Netherlands, with a French regional subsidiary (Sendot France) in Hérouville Saint-Clair. The company designs and manufactures a portfolio of portable optical sensors under the FluoMini Pro brand — covering oxygen, chlorophyll fluorescence, photosynthesis efficiency (EffPAR), pH, seed quality, and algae measurement — that enable non-invasive, plant-level and root-zone monitoring for greenhouse horticulture, seed production, ornamental cultivation, water quality, and academic research. The core technical differentiator is optochemical measurement (as opposed to electrochemical methods), which does not consume oxygen during readings and is offered in analog 4–20 mA versions for direct climate-computer integration. Sensor data is aggregated through the company's SenBox data platform, which supports internal-network or standalone 4G connectivity, and exported via a Sendot software suite to .txt/Excel.

The company generates revenue through hardware sales and rentals of its sensor portfolio, supplemented by professional services including data interpretation and cultivation advice, custom sensor R&D, and digitalization/innovation consulting. Its go-to-market is consultative and demonstration-driven, employing a documented six-step sales process that includes free demonstrations, a typical 3–6 week production lead time, delivery, training, two-week post-sale follow-up, and ongoing customer engagement via quarterly newsletters. Distribution is direct in the Netherlands and France, with remote/inside sales reaching international prospects; the corporate website is available in five languages (Dutch, English, French, Spanish, German). End customers are predominantly European commercial growers (e.g., Gitzels Plant Nursery, Maarel Orchids, Butterfly Orchids), seed companies, water quality firms (microLAN), and research institutes, with strategic co-development partners including Plant Lighting and 30MHz.

Core offering

Sendot Research B.V. designs, manufactures, and sells optical sensors for agriculture and horticulture, including the FluoMini Pro line for measuring oxygen, chlorophyll fluorescence, photosynthesis, pH, seed quality, and algae. These sensors feed the SenBox data platform for continuous monitoring, and are complemented by data interpretation, innovation consulting, and custom sensor development services.

Product overview

Sendot Research B.V. offers a portfolio of optical sensor products for agriculture and horticulture applications, centered on the FluoMini Pro sensor line. The core product family includes specialized sensors for measuring oxygen (O2), chlorophyll fluorescence (CF), photosynthesis efficiency (EffPAR), pH, seed quality, and algae in various growing environments. These sensors feed data into the SenBox data platform, which aggregates measurements for real-time monitoring. The company also provides complementary services including data interpretation and advice, innovation tracks for digitalization projects, and custom research and product development. The product architecture combines portable handheld sensors with a cloud-connected data platform, enabling both standalone measurements and integrated monitoring systems.
