The Noisy Scarecrow detects wildlife and intruders instantly, sends real-time alerts to your phone wherever you are, and automatically activates sound and light deterrents to protect your crops and livestock day and night—eliminating the need for constant supervision.

Yield Loss Avoided
Rural smallholders lose 25% to 50%+ of their seasonal harvest to crop raiding and human theft. Standard defenses simply cannot keep pace.
Pests like baboons and monkeys quickly recognize repetitive scarecrows and banging tins as harmless. Within 48 hours, intrusion rates return to baseline.
Modern IoT security designs assume grid electricity and high-speed internet. These designs exclude rural farms where connectivity is absent.
Shifting rain seasons and mid-season dry spells dry out wildlife food reserves, driving high levels of crop-raiding wildlife into cultivated plots.
Security devices left in open fields are primary targets for theft themselves. 45% of farmers surveyed listed device safety as their chief concern.
We replace ineffective, manual deterrence with an integrated, offline-first smart security ecosystem. The Noisy Scarecrow combines heavy-duty physical field nodes with local app interfaces to protect crops at the edge.
Configure settings and sync farm event histories via local Bluetooth BLE. No internet costs.
A self-charging system backed by batteries to operate day and night in off-grid environments.
Randomized cycles of high-decibel sounds and blinking LED strobes defeat pest habituation.
Integrated motion and proximity sensors trigger a local alarm if the device is handled.
How data flows seamlessly from field sensors to the mobile companion app without internet connectivity.
PIR trackers monitor coordinates
Edge logic sounds randomized sirens
Sync logs to phone with zero data cost
Farmer verifies events & tracks statistics
Secure plots and confirm alarms
A comprehensive features layout designed to support both individual plots and large-scale farming operations.
Wide-angle PIR motion sensors detect crop-raiding wildlife and unauthorized intruders automatically.
Powered by a 10W solar panel and a rechargeable 12V 7Ah backup battery for continuous, round-the-clock protection.
Operates fully offline using BLE 5.0. Change settings and retrieve logs without any internet fees.
Monitor security parameters, verify active motions, and analyze historical data from one location.
Digitally trace your boundaries and subdivisions on custom maps to localize motion triggers.
Assign dedicated managers or local workers to supervise specific divisions and handle local alerts.
Verify triggers within a 30-second window. Stops false alarms before audible sirens are triggered.
Automated API token provisioning secures device integrations and prevents spoofing attacks.
A simple, secure onboarding process that gets your fields protected within minutes.
Create your AgriSentinel account. Enter your farm boundaries and generate a secure, unique hardware API key to register your scarecrow node.
Divide your farm into specific monitored zones (e.g. maize_plot, apiary_zone). Assign phone profiles and local supervisors to receive local alerts.
Mount the weatherproof grey box and solar assembly at a critical boundary or field entry point. Pair it via BLE to complete installation.
The PIR sensors monitor boundary lines. Motion triggers randomized audio loops and flashing strobe sequences on the hardware unit.
A BLE push notification arrives on the phone. The supervisor has 30 seconds to confirm the motion as authorized (silencing the alarm).
If unconfirmed, the alarm is activated. The system logs an Unauthorized Intrusion in the database, updating charts and notifying managers.
A high-fidelity console showing active divisions, maps, intrusion histories, and sensor logs.

Wildlife crop raiding is concentrated around crop growth stages. Mutasa district surveys show:
Intrusions deterred using randomized audio and strobe patterns compared to traditional static methods.
Coordinates represent registered boundary mappings utilized to synchronize device alert sectors.
Hover or click component hotspots to reveal specifications of the self-contained physical security node.
Select any numerical hotspot on the hardware illustration to view technical specifications, wiring configurations, and sensor thresholds.
AgriSentinel’s technologies originate from formal research at Africa University, designed to bridge the technology access gap for climate-stressed smallholders.

Bespoke field configuration
No. Pairing, parameter configurations, and security log synchronization operate completely offline via local Bluetooth Low Energy (BLE). No data connection is required.
The device is entirely solar-powered, charging an internal 12V backup battery via a 10W solar panel to guarantee uninterrupted, autonomous runtime.
Conventional static alarms cause animal habituation within days. AgriSentinel utilizes randomized multi-sound cycling (alternating barking dogs, whistling, and shouting) coupled with flashing LED strobes and spinning parts to ensure deterrents remain unpredictable.
Yes. Based on farmer concern surveys, we integrated touch-sensitive proximity sensors into the device casing. If the scarecrow is handled or moved, a high-decibel local alarm immediately sounds.
