This document serves as a family models declaration letter from Dragino Technology Co., Limited, dated May 23, 2025. It outlines the differences between various models within the LHT65S and LHT65N series of temperature and humidity sensors. The core functionality, including the circuit and RF module, remains consistent across all models. The primary distinction lies in the type of sensor probe integrated into each variant.
The document lists the specific models, including LHT65S-E3, LHT65S, LHT65S-NE117, LHT65S-E5, LHT65S-PIR, LHT65S-E31F, LHT65N, LHT65N-NE117, LHT65N-E3, LHT65N-E5, LHT65N-PIR, and LHT65N-E31F. It details the sensor probe type for each model, such as external temperature sensors, external illumination sensors, and external light sensors. Some models, like LHT65S and LHT65N, are noted as having no sensor. The FCC ID for the series is identified as ZHZLHT65S-E3. The document is signed by Edwin Chen, manager at Dragino Technology Co., Limited.
