It communicates with the target microcontroller over the PWM
The Power Save jumper onboard is enabled by default - this features dramatically reduces the power consumption because the battery power is only used if a click board and Hexiwear are connected to it
-40°C ～ +85°C
and Snow Level with varying detection range
it is crucial to know whether they are far enough away from each other and if the area that should be covered by the gateways is within range at any location
S31 NB-IoT LTE CAT-M Temperature Humidity Sensor Power Option:Includes with Replaceable 19000mAh Battery It communicates with the targetS31 NB IoT LTE CAT M Temperature Humidity Sensor The Dragino S31 is an NB IoT and LTE CAT M Temperature and Humidity Sensor for Internet of Things solutions. It is used to measure the surrounding environment temperature and relative air humidity precisely, and then upload to the IoT server cloud via NB IoT and LTE CAT M network. The temperature & humidity sensor used in S31 is SHT31, which is fully calibrated, linearized, and temperature compensated
