The sensor features IP67 protection, onboard storage for historical records, support for data retransmission, and NFC configuration for easy setup.
Advantages
The EM300TH915M provides precise readings with ±0.3°C temperature accuracy and ±3% RH humidity accuracy over an operating range of -30°C to 70°C and 0% to 100% RH. Its IP67-rated enclosure enables use in wet or dusty environments. Onboard memory stores up to 2800 historical data records that cannot be manually deleted, preserving traceability. Retransmission capability improves communication reliability by ensuring data reaches the server even during intermittent network outages. NFC-based switching and configuration simplify deployment and maintenance.
Suitable for
Indoor climate monitoring in offices, storage rooms, and laboratories
Outdoor environmental monitoring where IP67 protection is required
