  • Page 3: Introduction

    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.

    4. Set up Instruction On/Off Insert batteries. (Users may need a screwdriver to open battery cover.) Power on Press and hold the function key for 3 seconds until the green indicator flashes. Turn on Turn off (Reset to factory setting) Press and hold the function key for 5 seconds until green indicator flashes fast for 20 times.

  • Page 6: Data Report

    1. The interval of the data reports might vary due to the firmware. 2. The interval between two reports must be the minimum time. 3.Please refer to the Netvox LoRaWAN Application Command and http://www.netvox.com.cn:8888/cmddoc for devices’ data analysis. Data report configuration and sending period are as following:...
  • Page 7 Tips 1. Battery Voltage: The voltage value is bit 0 ~ bit 6, bit 7=0 is normal voltage, and bit 7=1 is low voltage. Battery=0xA0, binary=1010 0000, if bit 7= 1, it means low voltage. The actual voltage is 0010 0000 = 0x20 = 32, 32*0.1v =3.2v 2.

  • Page 12: Information About Battery Passivation

    MinTime/MaxTime calculation is started. 6. Information about Battery Passivation Many of Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many advantages including low self-discharge rate and high energy density. However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high.
