The Milesight TS201-TH is a compact and precise LoRaWAN® temperature and humidity sensor designed for pharmaceutical storage, food cold chain, warehouses, greenhouses, laboratories, and other climate-sensitive applications.
It features a detachable digital temperature and humidity probe based on CMOSens® MEMS technology 🔧, offering temperature monitoring from -40°C to +125°C and humidity measurement from 0% to 100% RH. The rugged IP67-rated enclosure 🛡️ ensures reliable operation in demanding environments.
With EN12830 certification and support for HACCP requirements 📜, the TS201-TH is suitable for applications requiring reliable and auditable environmental monitoring.
The device can locally store up to 4,000 data records 🧾 and supports automatic retransmission after temporary LoRaWAN network interruptions. Its long-life battery provides approximately 9 years of operation under specified conditions.
Configuration is easily performed via NFC 📲 or LoRaWAN downlink, while flexible wall, cable-tie, or optional magnetic mounting 🧲 simplifies installation.
