The Dragino LHT52<\/strong> is a ready-to-use, multifunction LoRaWAN sensor for reliable measurement of temp\u00e9rature<\/strong> andRelative humidity<\/strong> in an indoor environment. Compact, battery-powered and easy to integrate into a home automation system based on a Raspberry Pi<\/strong>, it is perfect for creating a comfortable, smart controlled home.<\/p>\n

Main features and versatility<\/h3>\n
    \n
  • It combines a temp\u00e9rature<\/strong> sensor and a Relative humidity<\/strong> integrated.<\/li>\n
  • These measurements are transmitted via LoRaWAN (version 1.0.3, class A)<\/strong>, ensuring low power consumption and long range.<\/li>\n
  • Option to connect an external temperature probe<\/strong> (via Type-C port), for remote measurement or measurement inside another material.<\/li>\n<\/ul>\n

    Long battery life<\/h3>\n
      \n
    • Runs on 2 AAA batteries<\/strong>, which are easy to replace.<\/li>\n
    • Battery life of up to several years<\/strong>, depending on transmission frequency.<\/li>\n
    • Very low standby consumption (~5 \u00b5A), with reasonable peaks (<110 mA) during transmission.<\/li>\n<\/ul>\n

      Data logging and smart alarms<\/h3>\n
        \n
      • Features internal memory (datalogging)<\/strong> to store readings in the event of network loss, with the option to retrieve them later on request.<\/li>\n
      • Includes a Temperature alarm<\/strong> : if a threshold is exceeded, it sends an alert immediately without waiting for the next transmission cycle.<\/li>\n<\/ul>\n

        Dynamic configuration<\/h3>\n
          \n
        • Remote configuration via AT commands<\/strong> or via LoRaWAN downlink<\/strong> : change the transmission interval, enable the alarm, set the temperature range, etc.<\/li>\n
        • Supports remote firmware updates (OTA), keeping the device up to date without physical handling.<\/li>\n<\/ul>\n

          Home automation with Raspberry Pi<\/h3>\n

          By combining the sensor with a LoRaWAN gateway controlled by a Raspberry Pi<\/strong>, you can:<\/p>\n

            \n
          • View temperature and humidity values in real time via Home Assistant or Node-RED.<\/li>\n
          • Set up automations: trigger a fan, a ventilation system or an alarm if the humidity level exceeds a threshold.<\/li>\n
          • Send instant notifications (mobile, email, sound, light).<\/li>\n
          • Keep a data history to analyze trends and optimize comfort and energy consumption.<\/li>\n<\/ul>\n

            Installation and ergonomics<\/h3>\n
              \n
            • Discreet wall-mounted or desktop format, ideal for a living room, a bedroom or a technical room.<\/li>\n
            • Built-in LED shows the operating status (network, transmission, alarm).<\/li>\n
            • Simple installation with a wall mount or freestanding; no external power supply required.<\/li>\n<\/ul>\n

              Long-term confidence and reliability<\/h3>\n
                \n
              • Compatible with many LoRaWAN networks (EU868, US915 regions, etc.).<\/li>\n
              • Versatile enough to meet the needs of indoor comfort, food storage or technical monitoring.<\/li>\n
              • Runs uninterrupted for years, with no need for frequent intervention.<\/li>\n<\/ul>\n

                Conclusion<\/h3>\n

                The Dragino LHT52<\/strong> is an excellent choice for equipping a smart home with accurate, self-powered environmental measurements. Paired with a Raspberry Pi, it becomes a central element of a smart home automation strategy: sensor, alarm and automated dashboard, all with minimal wiring and maximum convenience.<\/p>","protected":false},"excerpt":{"rendered":"
