Smart Doormat — know what happens at your doorstep, remotely

End-to-end development of a connected doormat: custom ESP32 hardware, UI/UX and a companion mobile app. It detects motion, weight and distance, tells a person from a pet, plays custom alert tones and logs every visit for you to review later.

Inside the project

From doorstep to app, in three layers

The solution concept, the hardware engineering underneath it, and the mobile experience on top — as designed and built by Justenable.

Smart Doormat solution overview — motion detection up to 5 m, 360° scanning, person vs animal detection by weight — The doormat watches the doorstep: movement detection up to 5 m, 360° scanning, and person-vs-pet recognition by weight (~70 kg person, ~25 kg animal) — with custom music on approach.

Smart Doormat hardware — ESP32-C6, 4-layer PCB, ADC DAC and touch sensor, motion and weight sensors — ESP32-C6 based board on a 4-layer PCB with ADC, DAC and touch sensing — engineered in-house from component selection through fabrication to final production.

Smart Doormat companion app — visit history with visual path diagram, family members, alert tones, live notifications — The companion app keeps a visit history with visual path diagrams, supports multiple family members, custom alert tones, and live movement notifications.

Scope of work

What the doormat can do

01 Hardware Development
02 UI/UX Design & Research
03 Mobile App Development

Motion detection

Spots movement up to 5 m from the door and tracks its direction toward the mat.

Weight sensing

Tells a ~70 kg person from a ~25 kg pet, so alerts say who is actually at the door.

360° scanning

Full-circle scanning of the doorstep area — nothing approaches unnoticed.

Custom alert tones

Plays music or a chosen tone as someone comes closer — pick per event in the app.

Visit history

Every detection is logged with a visual path diagram you can replay later.

Remote access

Wi-Fi + BLE connected with live notifications, shared with multiple family members.

Every project gets its own page like this one.

Bheru Smart Timer

A secure timer-controller on Nordic nRF52840 that drives industrial hooters across hospitals, schools and factories — shift schedules, lunch breaks and emergency alerts, all set from a mobile app over Bluetooth.

Smart Wi-Fi Plug

An ESP32-based smart plug that controls multiple devices from one app: lamp scenes for morning, night and evening, per-device schedules, shared family access, and power-consumption reports you can compare and download.

Smart RO Filter

A connected RO purifier that analyses every filter stage over Wi-Fi and Bluetooth: input vs pure vs waste water ratios with chemical details, automatic tickets when a cartridge wears out, and a notification for every conduction change.
