Field intelligence
delivered quietly.

Terrin monitors your crops continuously — tracking temperature, soil moisture, and early disease — and sends you what matters through the channels you already use.

Technology

A sensor that belongs in the field

Terrin is a small, solar-powered device that moves between crop rows. It reads temperature, humidity, and soil moisture continuously. Its camera scans leaves for early signs of disease as it works through the field.

It runs on sunlight. It connects over WiFi. When something changes — a temperature spike, soil drying out, a leaf that looks wrong — it tells you through WhatsApp. No app. No login. No behaviour change.

Every reading is logged and builds over seasons. A growing record of how your particular field behaves: which rows dry fastest, when disease risk peaks, what normal looks like.

Process

From field to phone — without any app

01
Self-powered
A solar panel keeps the battery charged through the day. In typical field conditions Terrin runs indefinitely without any intervention.
02
Connects over WiFi
Uses a hotspot from your existing mobile phone. No router, no broadband, no infrastructure in the field required.
03
Monitors continuously
Temperature, humidity, and soil moisture logged every 30 minutes. The camera scans leaves for colour changes and texture anomalies that precede visible crop stress.
04
Delivers to WhatsApp
When something requires attention, a message arrives with a photo, the row number, and a plain description. Supported by SMS and weekly PDF reports.
Delivery

Intelligence through the channels you already use

A message, not a dashboard.

When Terrin identifies something, a WhatsApp message arrives — a photo from the device camera, the row and plant location, what was detected, and what it might indicate. The farmer decides what to do.

For agronomists managing multiple farms, all alerts consolidate into a single view — one line per farm, status at a glance. No setup, no training.

Once a week, Terrin generates a one-page field report: temperature range, soil moisture trend, any anomalies flagged. Delivered to WhatsApp as a PDF. Printable. Suitable for farm visits or client briefings.

API access available for insurers, lenders, and enterprise integrations. Timestamped, geotagged, verifiable.

What it records

A continuous picture of your field

Every reading is stored. Over time, Terrin builds a detailed log — useful for planning, insurance evidence, agronomic decisions, and understanding why seasons differ.

How it compares

Against other farm monitoring methods

Every approach to farm monitoring has a different set of trade-offs. Here is how Terrin sits against the tools farmers and agronomists currently use.

Terrin Satellite imagery Drones / UAVs Stationary IoT Manual scouting Farm weather station
Works between crop rows Ground level Aerial only Flies over Fixed point With labour Fixed pole
Continuous monitoring 24 / 7 ~ Every 3–5 days Flight by flight Fixed location When visited Weather only
