Introducing Kathi

One small box. Temperature, humidity, and illumination — all in one, all wireless.

Kathi is a compact environmental sensor designed to pair seamlessly with the Yiem Smart Farm Controller. It measures three of the most important growing conditions in a single, unobtrusive device — and sends the data straight to your controller, wirelessly.

What Kathi Measures

  • Temperature — Keep an eye on the conditions your crops, livestock, or stored goods need.
  • Humidity — Monitor moisture in the air to catch problems before they spread.
  • Illumination — Track light levels, whether for growing spaces or light-sensitive environments.

Three sensors, one box, one connection. No tangled wiring, no complex setup.

Wireless to Your Controller

Kathi transmits its readings directly to your Yiem Smart Farm Controller — no cables, no fuss. It slots into your existing setup as another node in the network, feeding real-time data into the control logic so both rule-based and Model-Predictive modes have fresh inputs to work with.

Read It at a Glance

Kathi has a built-in mini LCD display that shows its current readings at a glance — temperature, humidity, and illumination right on the device. No app, no phone, no controller screen required to get an instant read on the environment around you.

A Trusted Cross-Check

Beyond the quick glance, Kathi is a reliable cross-check. Use it to verify what your controller is reporting, sanity-check sensor data in the field, or spot discrepancies before they turn into decisions. It's the second pair of eyes on your environment — always there, always accurate.

Built to Fit the Field

Small enough to place anywhere you need to watch the environment. Simple enough to trust without a manual. Designed to work as part of the Yiem ecosystem, not against it.

Pair It With Your Controller

Kathi feeds clean, wireless environmental data into your Yiem Smart Farm Controller — the same data that powers offline rule-based control and, when connected, Model-Predictive Control with a Digital Twin. More inputs means smarter decisions, whether you're offline or online.

This is an early-stage product launch. Availability, pricing, and pairing details coming soon.
