R718B connects an external resistance temperature detector (PT1000) to measures the temperature.

• Adopt SX1276 LoRa wireless communication module
• 2 ER14505 battery AA SIZE (3.6V / section) parallel power supply
• PT1000 Platinum resistance temperature sensor detection
• The base is attached with a magnet that can be attached to a ferromagnetic material object
• Protection class IP65 / IP67 (optional)
• Compatible with LoRaWANTM Class A
• Frequency hopping spread spectrum
• Configuration parameters can be configured via a third-party software platform, data can be read and alerts can be set via SMS text and email (optional)
• Applicable to third-party platforms: Actility/ThingPark, TTN, MyDevices/Cayenne
• Low power consumption and long battery life
Note:
Battery life is determined by the sensor reporting frequency and other variables, please refer to http://www.netvox.com.tw/electric/electric_calc.html
On this website, users can find battery life of various models in different configurations.
