WTH301 Temperature & Humidity Sensor: Smarter Cold Chain Monitoring in Kenya
For businesses transporting pharmaceuticals, vaccines, fresh produce, flowers and other temperature-sensitive goods, knowing where a shipment is only tells part of the story.
You also need to know what is happening to the cargo while it is being transported.
The WTH301 temperature and humidity sensor provides wireless environmental monitoring for cold-chain and sensitive-cargo operations. By monitoring conditions inside a vehicle, storage area or other controlled environment, businesses can gain greater visibility into the conditions surrounding their goods.
For Kenyan logistics operators moving temperature-sensitive products between warehouses, distribution centres, hospitals, farms, airports and customers, environmental monitoring can complement GPS fleet tracking and provide a more complete picture of the journey.
TrackAlways Africa provides fleet management solutions and telematics technologies for businesses operating across Kenya and East Africa.
What Is the WTH301?
The WTH301 is a compact Bluetooth Low Energy (BLE) temperature and humidity sensor designed for monitoring environmental conditions.
It is suited to applications where temperature and humidity can affect the quality, safety or condition of transported or stored products.
According to the TrackAlways product catalogue, potential applications include:
- Pharmaceutical logistics
- Fresh produce delivery
- Warehouse cold storage
- Floral transport
The wireless design allows the sensor to communicate with compatible telematics gateways without requiring a conventional wired connection between the sensor and tracking device.
Why Is Temperature Monitoring Important in Cold-Chain Logistics?
A refrigerated vehicle can be moving normally while the conditions inside its cargo area are changing.
Temperature can be affected by several factors, including:
- Refrigeration equipment performance
- Frequent door opening
- Loading and unloading
- Poor air circulation
- Extended stops
- Changes in ambient conditions
- Incorrect cargo placement
Without continuous monitoring, operators may only discover a temperature problem after the shipment reaches its destination.
The World Health Organization's guidance on temperature monitoring in vaccine supply chains highlights the importance of appropriate temperature-monitoring and recording practices in cold-chain operations.
How Does the WTH301 Work?
The WTH301 uses Bluetooth Low Energy to transmit temperature and humidity information to a compatible gateway.
The TrackAlways product catalogue identifies compatibility with 4G telematics gateways such as the FMB150 and Queclink GV series.
This allows environmental information to become part of a wider telematics setup rather than operating as an isolated temperature sensor.
For example, a logistics operator could combine:
- Vehicle GPS location
- Temperature information
- Humidity information
- Trip history
- Alerts
- Fleet reports
This provides a broader view of both the vehicle and the cargo environment.
WTH301 for Pharmaceutical Logistics
Pharmaceutical products can pass through several stages before reaching their destination.
A typical journey may include:
- Cold storage
- Vehicle loading
- Road transportation
- Distribution centre
- Hospital or pharmacy delivery
Every stage introduces opportunities for environmental conditions to change.
A wireless temperature and humidity sensor can help logistics teams maintain a digital record of conditions during transportation and storage.
For businesses looking for a broader cold-chain solution, TrackAlways Africa can also integrate environmental monitoring into wider fleet tracking and telematics solutions.
Monitoring Fresh Produce and Flowers
Kenya's agricultural and horticultural industries depend on efficient transportation from farms and collection centres to warehouses, markets, airports and customers.
Fresh produce and flowers can be particularly sensitive to environmental conditions.
The WTH301 can provide temperature and humidity information that helps operators understand the conditions surrounding shipments during transportation.
This can be especially useful for businesses managing:
- Fresh vegetables
- Fruits
- Flowers
- Pharmaceutical products
- Other temperature-sensitive cargo
What Are the Benefits of Wireless Temperature Monitoring?
A wireless sensor can simplify the process of adding environmental monitoring to an existing telematics system.
Some potential benefits include:
- Reduced wiring requirements
- Flexible sensor placement
- Continuous environmental visibility
- Integration with compatible telematics gateways
- Easier deployment across multiple vehicles or storage areas
For fleet operators managing several refrigerated vehicles, standardising environmental monitoring can also make it easier to build consistent monitoring processes.
WTH301 Frequently Asked Questions
What does the WTH301 measure?
The WTH301 monitors temperature and humidity.
Is the WTH301 wireless?
Yes. It uses Bluetooth Low Energy (BLE) for wireless communication with compatible telematics gateways.
Where can the WTH301 be used?
The product is designed for applications including pharmaceutical logistics, fresh produce delivery, warehouse cold storage and floral transport.
Can the WTH301 be used with GPS tracking?
Yes. It can communicate with compatible telematics gateways, allowing temperature and humidity information to be combined with vehicle tracking data.
Why monitor humidity as well as temperature?
Temperature is not the only environmental condition that can affect sensitive products. Humidity monitoring provides additional information about the environment surrounding the cargo.
Build a More Visible Cold Chain
GPS tracking tells you where your delivery is. Environmental monitoring can help you understand the conditions surrounding the delivery.
For pharmaceutical distributors, fresh-produce businesses, flower exporters, cold-storage operators and other temperature-sensitive logistics companies, combining location and environmental data can create greater operational visibility.
