What Is IoT Logistics Tracking?
IoT (Internet of Things) logistics tracking is the use of connected sensor devices on vehicles, containers, and cargo to collect and transmit real-time data — location, cargo activity, temperature, door status, and physical events — to a central visibility platform. Where GPS tracking tells you where a truck is, IoT tracking tells you what is happening inside and around that truck.
In Indian logistics, IoT tracking addresses the most persistent blind spot in traditional GPS-only visibility: what happens to the cargo during transit. A truck can be exactly on route with perfect GPS coverage while cargo is being offloaded at an unauthorised stop — GPS shows no anomaly. IoT activity sensing using sensors at cargo level detects the unloading event directly, independent of vehicle location.
IoT Sensor Types in Indian Logistics
Activity Sensing (IAS Module)
Intugine's proprietary IAS (Intugine Activity Sensing) module uses activity sensing using sensors to detect physical events at vehicle level — unloading activity, door access, cargo movement, and vehicle body disturbance — without relying on driver reporting or video surveillance. The sensor transmits event data with GPS timestamp and location when activity is detected, creating a physical event log alongside the location track.
IAS is particularly effective for back-unloading detection in cement and coal logistics — where partial unloading at intermediate points is the primary grey-market mechanism — and for high-value cargo security monitoring across all sectors.
Temperature Sensors
IoT temperature sensors inside refrigerated compartments transmit readings every 5–15 minutes alongside location data. Critical for pharmaceutical, vaccine, dairy, and frozen food logistics where regulatory compliance requires continuous temperature documentation throughout the cold chain.
Door and Lock Sensors
Magnetic contact sensors on truck doors and container locks detect open/close events with GPS timestamp — providing an access log for every door opening during transit. Combined with geofencing, door sensor events outside approved loading/unloading locations trigger immediate cargo security alerts.
Weight and Load Sensors
Axle load sensors detect significant weight changes during transit — indicating unloading events even without cargo-level activity sensors. Less precise than IAS for partial unloading detection but useful as a validation layer for high-value bulk cargo.
IoT vs GPS: What Each Layer Adds
GPS tracking provides continuous vehicle location — essential, but insufficient alone for cargo security and compliance monitoring. IoT sensors add the cargo-level event layer that GPS cannot provide:
- GPS tells you: where the truck is, how fast it's moving, whether it deviated from route
- IoT tells you: whether cargo was accessed, whether temperature was maintained, whether the vehicle body was disturbed, whether an unloading event occurred
- FASTag tells you: which toll plazas the vehicle passed, highway movement validation independent of onboard devices
The combination — GPS location + IoT cargo events + FASTag highway validation — is Intugine's multimodal tracking stack for high-security logistics in India.
IoT Deployment in Indian Logistics: Practical Considerations
Hardware Installation
IoT sensor modules are installed on vehicles by trained technicians — typically a 30–60 minute installation per vehicle for a combined GPS + IAS unit. For transporter fleets, installation is coordinated through the transporter with Intugine's field team handling deployment.
Connectivity
IoT devices transmit over 2G/3G/4G cellular networks. In low-connectivity zones — remote highway stretches, industrial areas with poor coverage — devices store events locally and transmit in burst when connectivity is restored, ensuring no events are lost.
Power
Most logistics IoT modules draw power from the vehicle's electrical system. Battery-backed units maintain operation during ignition-off periods — important for parked vehicle monitoring and detention tracking.
ROI of IoT Logistics Tracking
The primary ROI drivers for IoT tracking beyond GPS are cargo theft and diversion prevention, regulatory compliance documentation (cold chain), and detention dispute resolution. Enterprises running high-value cargo on Indian highways — cement, coal, pharma, FMCG — consistently find that a single prevented cargo diversion incident recovers the annual IoT deployment cost across the entire fleet.
