LHT65S – Temperature & Humidity Sensor with External Probe – Dragino
General Description
Dragino 's LHT65S is a long-range LoRaWAN sensor for temperature and humidity monitoring. It features a built-in temperature and humidity sensor and an input for connecting an external temperature probe. Its built-in 2400 mAh non-rechargeable battery allows it to operate for up to 10 years, depending on the transmission frequency.
Compliant with LoRaWAN v1.0.3 Class A protocol, the LHT65S offers long-range wireless communication with low power consumption. It integrates a datalog function to locally save measurements in case of network loss, preventing any data loss.
