TOPFLYtech Launched TSTH-B BLE 5.0 Temperature & Humidity Sensor

10 December, 2019

TOPFLYtech TSTH1-B BLE 5.0 wireless temperature & humidity sensor is aimed at cold chain logistics and warehouse applications. It is designed to respond the industry demands for environment monitoring to resolve losses caused by unfriendly and unexpected temperature and humidity.

Why is temperature and humidity monitoring important?

When temperature changes and deviates from its pre-set due to mismanagement or machine breakdown, fresh stocks are put at risk of going bad. Big batches of high value products are wasted every year causing not only losses on the owner, but on our international economy. 

How does TSTH1-B work?

There are 2 ways of using this sensor. 

  1. It can connect and report straight to cell phone via BLE. The temperature and humidity figures will be shown on APP. 
  2. It can connect and report to a TOPFLYtech GPS tracker with BLE. The trackers then send the data to your server via network.

Where should we use TSTH1-B?

Refrigerated trucks, warehouses, supermarkets, storerooms, greenhouses, laboratories, you name it. Anywhere that requires a strict control of temperature or humidity can make great value out of TSTH1-B.

Here is a quick rundown of TSTH1-B specs:

  • BLE 5.0
  • Replaceable CR2477 battery (900mAh), up to 8 years battery life
  • Measuring range, -30℃~+60℃(-22℉~140℉)
