What Sentek Technologies does

Sentek Technologies is an Australian-headquartered designer, manufacturer, and global supplier of soil moisture, salinity, and temperature monitoring sensors for precision agriculture, founded in 1991 and based in Adelaide. Its core product platform comprises proprietary multi-depth probes (EnviroSCAN, Drill & Drop including Bluetooth variants, Diviner 2000, SoluSAMPLER), a fleet of telemetry units (BILBY, Wi-Fi Link, Nexus Blue, IoT DTU, PLUS Compact/Standard, MULTI, Satellite) and the IrriMAX Desktop and IrriMAX Live decision-aiding software, with site-specific calibration and a stated detection resolution of better than 0.01% moisture change. Hardware is paired with optional recurring IrriMAX Live subscriptions (12, 24, or 36 months) and an API access tier, generating a mix of one-time hardware sales and recurring software/data revenue, with SIM-card data plans available at roughly 1MB/month in Australia.

The company sells primarily through a global authorized dealer network providing installation, calibration, and analytical support, complemented by company-operated webstores in Australia and the USA and a wholly-owned Sentek USA subsidiary. Customers are concentrated in the agriculture vertical — farmers, growers, agribusinesses, and irrigation service providers — with secondary demand from research institutions and environmental monitoring applications, and the products are reported as deployed in over 80 countries. Sentek supports an open integration platform spanning Bluetooth, Wi-Fi, cellular (4G LTE, CAT-M, GPRS), SDI-12, and RS232/RS485, allowing its probes to feed third-party data loggers and farm management systems. The current leadership comprises CEO Nick Ktoris, with no public listing, parent company, venture or private equity funding, or M&A activity disclosed in the available source material.

Core offering

Sentek Technologies designs, develops, and manufactures in-house soil moisture, salinity, and temperature probes (EnviroSCAN, Drill & Drop, Diviner 2000, SoluSAMPLER) along with telemetry/data transmission units (BILBY, Wi-Fi Link, Nexus Blue, IoT DTU, PLUS, MULTI). These connect to the IrriMAX software platform (Desktop and cloud-based Live) for irrigation decision support, with an open integration platform allowing connection to third-party systems and an IrriMAX Live API for programmatic data access.

Product overview

Sentek Technologies offers a comprehensive soil moisture monitoring ecosystem designed, developed, and manufactured in-house since 1991. The product portfolio centers on soil data probes (EnviroSCAN™, Drill & Drop™, Diviner 2000™, SoluSAMPLER™) paired with telemetry solutions (Sentek BILBY®, Wi-Fi Link™, Nexus Blue, IoT DTU, PLUS Compact/Standard, MULTI) for data transmission. These integrate with IrriMAX™ Desktop and IrriMAX™ Live software platforms for irrigation decision support. The company provides both standalone components and integrated solutions like the PLUS All-In-One, which combines probe and telemetry in a single unit with 12-24 month battery life. Additional offerings include weather stations, dataloggers (RT6, SOLO), and various sensors. The ecosystem deploys across 80+ countries for agriculture, research, and environmental sectors.
