## Long description

The Milesight EM300TH915M Temperature & humidity sensor is a compact freestanding device for indoor and outdoor environmental monitoring. It measures temperature from -30°C to 70°C and relative humidity from 0% to 100% RH using a high-sensitivity Sensirion probe, and stores up to 2,800 historical data records on the device. The sensor features an IP67-rated enclosure for water and dust protection and supports NFC configuration and on/off control from a mobile phone or PC. Built for reliable data delivery, it supports retransmission to ensure the web server receives data even after temporary network outages.
Advantages
The sensor provides high accuracy (±0.3°C for temperature and ±3% RH for humidity) and a long battery life enabled by a 4000 mAh power source. IP67 protection allows use in a wide range of environments, while onboard storage of 2,800 records preserves traceability because stored data cannot be manually deleted. Retransmission capability increases communication reliability, and NFC-based configuration simplifies setup and operation.
Suitable for
Indoor environmental monitoring in offices, server rooms, and laboratories
Outdoor monitoring in sheltered or exposed locations where IP67 protection is required
Cold chain monitoring and storage areas requiring temperature and humidity tracking
Industrial and agricultural applications that need robust, reliable data logging
