Silicon for
every wheel
in India.
VAAYU is India’s indigenous tyre-pressure monitoring system-on-chip. Sensing, a RISC-V controller and a 433 MHz radio on one die, for two-wheelers, cars and trucks, ICE and EV.

Why it matters
A few PSI is the difference between a trip and a blowout
Most tyre failures start with low pressure the driver cannot see or feel. A sensor in the tyre can.
Blowouts start as slow leaks
Under-inflation builds heat until the tyre fails, often at highway speed. A warning minutes after pressure starts to drop gives the driver time to stop.
Soft tyres burn fuel and range
Correct pressure lowers rolling resistance. For a fleet that means less diesel; for an EV it means more kilometres per charge.
TPMS is being mandated
AIS-154 in India and UN ECE R141 globally require tyre-pressure monitoring. The chips inside those systems are imported today.
VAAYU use cases
One chip, from scooters to eighteen-wheelers
The same SoC serves three vehicle segments, with petrol, diesel or electric drivetrains.
Inside the chip
From tyre air to dashboard warning
Digital, analog and RF are all designed in-house. The controller is RISC-V.
