Scope of work

What the dispenser can do

01 Hardware Development
02 Enclosure Design
03 In-house Manufacturing

Fully automated

Hands under, sanitizer out — the machine handles everything else.

Touch-less

Nothing to press means nothing to contaminate.

Adjustable flow

Dial the dose to the setting your space needs.

3-litre tank

A full working day (and then some) between refills.

HST technology

Fast, consistent actuation on every single dispense.

Our portfolio

More from our portfolio

Every project gets its own page like this one.

Smart Doormat

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.

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.
