platinum resistiveBluetoothLoRaWAN

Product summary
The SenseCAP S2107 is a battery-powered LoRaWAN temperature sensor using PT1000 platinum resistance probes. It measures −50 to 300 °C and supports up to three PT1000 channels. The unit features an IP66 enclosure, built-in Bluetooth for app configuration and OTA updates, and is intended for industrial monitoring, cold chain storage, food monitoring, liquid detection and aquaculture.

Key features

• Designed for harsh environments: IP66 enclosure and LoRa DTU rated for −40 to 85 °C; PT1000 probe range −50 to 300 °C.
• Global LoRaWAN compatibility: Universal frequency plan covering 863–928 MHz for quick integration with regional gateways.
• Long range & battery operation: Typical transmission range 2 km (urban) to 10 km (line-of-sight); replaceable Li-SOCl2 battery (ER34615) with up to 10 years life depending on configuration.
• Easy configuration: Built-in Bluetooth and SenseCraft app for no-code setup, calibration and OTA parameter updates.

Hardware overview
The S2107 uses a PT1000 platinum resistance thermometer with three-wire support and allows up to three sensors to be connected simultaneously. It provides direct-contact temperature measurement suitable for liquids, food and storage cold chain, industrial boilers and aquaculture. The device is battery-powered for low-maintenance installations.
