Overview
WTH301 overview
Core Purpose
The WTH301 is a BLE temperature and humidity sensor built for logistics and transportation use. Its main role is to measure environmental conditions and pass that data to compatible BLE trackers, making it suitable for cargo that needs condition visibility during movement.
Connectivity and Communication
The device uses BLE 5.1 for short-range wireless communication and can transmit up to 150 metres in open areas. In practice, this allows it to work as a simple sensor node alongside Queclink BLE trackers without needing complex installation or wired connections.
Monitoring
The WTH301 monitors both temperature and humidity, which makes it useful for shipments that are sensitive to changing storage conditions. It samples data every 10 seconds, so condition changes can be captured regularly during transport rather than only at wide intervals.
Power and Environmental Suitability
The sensor is designed for demanding transport environments. It has an IP66-rated housing for water and dust protection, works in temperatures from -40 °C to +70 °C, and uses a 1200 mAh lithium iron battery rated for more than 3 years under the stated reporting conditions.
Installation
The unit is small at 75 × 38 × 19 mm and weighs 48 g, so it is easy to place in space-limited areas. Installation uses a 3M sticker, which supports fast and low-cost deployment in trailers, containers, and other logistics assets.

Applications
WTH301 applications
Cold Chain Logistics
This sensor fits cold chain operations because it tracks both temperature and humidity in transit. Its wide measurement range and regular 10-second sampling help teams monitor goods that need stable storage conditions.
Trailer Tracking
In trailer environments, the WTH301 adds condition monitoring to BLE-based tracking setups. Its compact size and simple sticker installation make it practical for quick placement inside transport equipment.
Container Tracking
For containers, the device helps operators keep watch over internal environmental conditions during storage and movement. The IP66 housing also makes it better suited to tough operating conditions where moisture and dust resistance matter.
Logistics and Transportation
Across general logistics fleets, the sensor supports better visibility into cargo conditions rather than location alone. When paired with compatible BLE trackers, it helps extend monitoring into loads that need environmental awareness during delivery and handling.
