Tea Processing | Temperature & Humidity Monitoring | LoRaWAN®


The history of Chinese tea is a long and gradual story of refinement. Generations of growers and producers have perfected the Chinese way of manufacturing tea. 

There are two to seven procedures are involved in the processing of fresh tea leaves, such as withering, fixing, oxidation, rolling, drying, and aging. Each of these procedures required high accuracy and high stability in temperature and moisture control to avoid spoilage due to excess moisture and fluctuating temperatures.



To provide a consistent, high-quality tea product, one of the tea manufacturers from Wuyishan contact us for a real-time environment monitoring solution.





In this project, the RS485 type oxygen sensor is connected to the UC500 series LoEaWAN controller via serial communication to detect the oxygen concentration of the ambient air. Featuring IP67 rating and wide operating temperature, the EM300-TH can be installed in the high heat tumble dryers to monitor the internal temperature and humidity, which makes sure the tea leaf drying process under the best conditions. While the EM500-PT100 temperature sensor is used for monitoring the temperature of tea processing machinery, to prevent equipment fault caused by long operating time. With multiple head type selections, The PT100 sensor can be attached to the internal components directly.


The Milesight UG65 LoRaWAN® gateway will receive all sensing data, and then it forwards all data to Milesight Cloud. Users can not only see visualized data on mobile phone but also get real-time alarms from anywhere.
