Wide Measuring Range: can measure air temperature range from -20 ~ 50°C and humidity range from 0 ~ 99.0 %RH(No Dew)
Low-power consumption: 2 x AAA LR03 batteries working for a long time up to 2 years
Long-range data transmission: Data can be transmitted within a range of 3~5 kilometers
Support for multiple platforms: Quick to use on platforms like Helium and TTN
Optional external probe: Supports external probes, such as the addition of surface temperature detection sensors.
Data retrievability: a maximum of 178 historical data items can be extracted through a downlink command for you to retrieve sensor value
Alarm Function: Not all the data is valuable. LHT52 enables you to focus on those data that you need to take action for
Flexible parameter configuration: Supports AT commands to change parameters, can remotely configure parameters through LoRaWAN Downlink
This sensor collects environment temperature and humidity and sends these values via long-range wireless LoRaWAN v1.0.3 protocol. It can work with the standard LoRaWAN gateway, like Helium hotspots SenseCAP M1, and TTN hotspots.
It also has Datalog capability to ensure sensor data won’t be missed. Every uplink data will be recorded, and you can retrieve these values via the downlink command.
Each LHT52 has unique LoRaWAN OTAA keys. To use LHT52 in a LoRaWAN network, you need to input the OTAA keys in the LoRaWAN network server, only then it can start to transmit data. The default period for each uplink is 20 minutes.
You can set a threshold value that you need to be notified or take action to. When the temperature or humidity exceeds that pre-configured range, it will send an uplink immediately. The alarm mode can be modified by AT command or downlink. Note: the alarm mode is disabled by default. If you need to enable the Alarm mode, please refer to the user manual.
Note
LHT52 is mainly used for indoor environment monitoring. If you need a sensor that meets the industrial standards, you can choose SenseCAP S2101 LoRaWAN Air Temperature and Humidity Sensor, which can work from -40℃ to 80 ℃ and has IP66 rugged case to withstand exposure to an outdoor environment. S2101's built-in 19Ah battery can support up to 10 years of usage while built-in Bluetooth can enable 1 minutes integration to quickly get it started.
