1. Introduction
R718CKAB: The temperature/humidity sensor and K-type thermocouple can respectively detect the temperature and humidity, and an
object's surface temperature. The temperature measurement range of R718CK is -40 °C to +375°C. R718CK has the
features of good linearity, larger thermal electromotive force, high sensitivity and stability. It should not be used in
sulfuric environments, reducing, oxidizing, and vacuum atmospheres, or weak oxidizing atmosphere.
R718CTAB: The temperature/humidity sensor and T-type thermocouple can respectively detect the temperature and humidity, and an
object's surface temperature. The temperature measuring range of R718CT is -40 °C to +125°C but it works more stably in
the range of -40°C to 0°C.
R718CNAB: The temperature/humidity sensor and N-type thermocouple can respectively detect the temperature and humidity, and an
object's surface temperature. The temperature measuring range of R718CK is -40 °C to +800°C, which is wider than other
types of thermocouples.
LoRa Wireless Technology:
LoRa is a wireless communication technology that adopts techniques such as long-distance communication and low power
consumption. Compared with other communication methods, LoRa spread-spectrum modulation techniques greatly expand the
communication distance. It is used in long-distance and low-data wireless communications like automatic meter reading, building
automation equipment, wireless security systems, and industrial monitoring control system. The features include small size, low
power consumption, long transmission distance, and anti-interference ability.
LoRaWAN：
LoRaWAN built LoRa’s end-to-end standards and techniques, ensuring interoperability between devices and gateways from different
manufacturers.
