What Sentek does

Sentek Technologies is a privately held Australian manufacturer founded in 1991 and headquartered in Stepney (Adelaide), South Australia. The company designs, develops, and manufactures in-house soil moisture, salinity, and temperature probes (including EnviroSCAN, Drill & Drop, Diviner 2000, and SoluSAMPLER), a range of telemetry devices (BILBY, Wi-Fi Link, Nexus Blue, IoT DTU, PLUS Compact/Standard, MULTI), and irrigation decision-aiding software (IrriMAX Desktop and the subscription-based IrriMAX Live cloud platform). The company also offers weather stations and an open integration platform enabling connections to third-party data loggers, irrigation controllers, and satellite imagery systems.

Sentek serves end customers across four primary verticals: agriculture (the core market covering orchards, vineyards, row crops, and pasture farming), landscapes (parks, golf courses, sports fields), scientific research, and mining/environmental projects. The company holds ISO 9001:2015 certification and operates a wholly-owned Italian subsidiary (Sentek SRL) that functions as its European data processor under GDPR. Its products have been deployed in over 80 countries.

Sentek's go-to-market is predominantly indirect, relying on a curated global network of authorized dealers who handle local sales, installation, training, and ongoing support. Direct enterprise engagement is supported by regional managers. Revenue is generated primarily through one-time hardware sales of probes and telemetry units, complemented by recurring IrriMAX Live software subscriptions, weather station sales, and ancillary professional services and training. The company has 11-50 employees and no disclosed external funding, acquisitions, or leadership changes in the available record.

Core offering

Sentek designs, develops, and manufactures soil moisture, salinity, and temperature data probes, telemetry and data transfer devices, and the IrriMAX irrigation decision-aiding software platform, marketed under its own brand and sold through a global authorized dealer network to agriculture, research, and environmental customers. The offering combines proprietary in-house sensor hardware with cloud and desktop decision-support software, integrating with third-party weather stations, data loggers, irrigation controllers, and satellite imagery.

Product overview

Sentek offers a comprehensive soil moisture monitoring ecosystem comprising hardware sensors (soil data probes, telemetry devices, weather stations) and software (IrriMAX Desktop and Live platforms). The core products include soil data probes (EnviroSCAN, Drill & Drop with Bluetooth variants, Diviner 2000, SoluSAMPLER) that measure soil moisture, salinity, and temperature. These connect through a range of telemetry solutions (BILBY, Wi-Fi Link, Nexus Blue, IoT DTU, PLUS variants, MULTI) that transmit data to IrriMAX software platforms for analysis and irrigation decision-making. The company also provides an open integration platform enabling connections to external technologies including weather stations, data loggers, irrigation controllers, and satellite imagery systems.
