TWD-1500 — Smart Trailer Monitoring System

Axle Monitoring + TPMS. One System. Complete Protection.The TWD-1500 is an axle temperature monitoring system and tire pressure monitoring system (TPMS) in one. It watches both failure points that cause trailer breakdowns — overheating bearings and underinflated tires — in real time, on your phone, while you drive. Bluetooth 5 mesh networking, no-drill magnetic sensors, IP67 waterproof.85% of trailer blowouts are preventable. The average roadside failure costs $1,800–$4,000. The TWD-1500 costs less than one service call.No Repeaters. No Missed Broadcasts.The TWD-1500 uses a Bluetooth 5 mesh listening network that ensures every TPMS sensor broadcast is heard — every time. Unlike traditional TPMS systems that rely on repeaters or boosters to extend range, the TWD-1500s mesh architecture picks up sensor data across your entire trailer without any additional hardware. Missed TPMS updates are a thing of the past.Just Count Your AxlesSelect your axle configuration below.
