LHT65S – LoRaWAN Temp & Humidity Sensor
Overview
$170 per unit (USD)
The LHT65S is a long-range, battery-powered LoRaWAN Class A sensor that precisely measures ambient temperature and humidity, with support for an external temperature probe. Designed for robust, low-power IoT environments, it’s ideal for continuous cold-chain and environmental monitoring across food, logistics, facilities, and industrial sectors.
Key Features
