01
Full-stack in-house
Sensors, receivers, repeaters, displays and the 4G cloud platform — developed by one team.
Engineer-led manufacturing, from sensor to cloud
Shenzhen Guangzhan Electronics Co., Ltd. designs and manufactures connected-vehicle and industrial IoT tire pressure monitoring systems. Our own hardware and embedded software teams build the full chain, which is why customisation does not stall.
02
Multi-protocol
CAN, RS485, Profinet, RS232, Modbus RTU and BLE, so data lands in the system you already run.
03
Industrial grade
IP68 sealing, −40 °C to +125 °C sensor range. Internal sensors are specified for 5+ years of battery life. External sensors use a replaceable CR1632 cell.
04
OEM/ODM
Protocol, firmware, enclosure, display UI, packaging and API are all open to customisation.
Company profile
GZVIA is an engineer-led manufacturer of connected vehicle and industrial IoT solutions. We design and build tire pressure monitoring systems — from standalone units to CAN-bus networked editions with 4G cloud telemetry — as well as wireless sensing products for fleet operators, heavy equipment OEMs and industrial integrators.
Our in-house hardware and embedded software teams deliver custom firmware, protocol adaptation and remote monitoring — from sensor to cloud — in OEM or ODM models.

Some customers ask not to be named publicly. Where that applies, references can be provided under NDA during evaluation.
Certification and compliance
Certification is scoped per market and per programme. Tell us your target market and we will confirm the standards that apply, the test house we use, and the timeline.
- CE (EMC / LVD) — industrial TPMS line: quoted per programme against your target market
- FCC / CE — BLE line: scoped together with your order plan and target market
- Certification is included as a workstream in OEM/ODM programmes, from test scoping to report handover
If a tender requires specific certificates, send us the specification and the destination market and we will confirm what applies.
How we work with you
- Scope — vehicle type, wheel count, interfaces, environment, target price.
- Proposal — configuration, wiring plan, sensor count, unit price and lead time.
- Sample — bench and on-machine evaluation, with engineering support.
- Production — scheduled delivery; payment commonly 30 % deposit / 70 % before shipment.
What we actually have
-
01
In-house engineering
Hardware, firmware, RF, cloud and mechanical teams — a change request does not wait on an outside supplier.
-
02
Sensor and receiver assembly
SMT and assembly in Shenzhen, with calibration on our own test benches.
-
03
Calibration and test benches
Pressure calibration (100% of units), immersion leak test, RF range test, full wheel-count integration and battery profiling.
-
04
Fleet platform
Our own 4G cloud platform, running live customer fleets — not a reseller arrangement.
Inside our factory
From SMT and calibration to immersion, RF test and burn-in — filmed on our own line.
Every sensor gets an immersion test
Immersed, inspected for water ingress, then re-tested. Bubbles mean a leak.
Certification is scoped per market and per programme. Tell us your target market and we will confirm the standards that apply, the test house we use and the timeline. A documented change-control process applies to every production run.
Tested, not just assembled
Every unit passes in-house testing before shipment — 100% pressure calibration, immersion, RF range, RF centre frequency, full wheel-count simulation and burn-in.

Technical questions go to our engineers, not to a sales script.
