["DRAGINO LHT65S-EU868-E5 LoRaWAN Temperature, Humidity and Light Sensor The Dragino LHT65S-E5 Temperature, Humidity and Lighting sensor is a LoRaWAN sensor with a large range. Has a built-in temperature and humidity sensor as well as an external lighting sensor. The LHT65S-E5 allows users to send data and reach extremely wide ranges. Is bietet Spreizspectralkommunikation mit extrem großer Reachweit und hohe Störfestigkeit bei minimalem Stromverbrauch. Is eignet sich für professional wireless Sensor network applications such as irrigation systems, intelligent Zähler, intelligent Städte, Gebäudeautomatisierung etc. The LHT65S-E5 has a built-in non-rechargeable 2400 mAh battery that can be used for more than 10 years*. The LHT65S-E5 is fully compatible with the LoRaWAN v1.0.3 Class A protocol and can be operated with a standard LoRaWAN gateway. *The actual battery life depends on how often the date is sent. Through the external antenna, the sensor can achieve better coverage than the LHT65N-E5", "LoRaWAN Class A protocol", "Frequency bands: EU868", "AT commands for changing parameters", "Remote configuration parameters via LoRaWAN downlink", "Firmware upgrade possible via program port", "Built-in 2400mAh battery for more than 10 years of use", "Built-in temperature and humidity sensor", "External lighting sensor", "Three-color LED for status display", "Wireless alarm and security systems", "House and building automation", "Industrial monitoring and control", "Long distance irrigation systems, etc", "Built-in temperature sensor: Resolution: 0.01°C", "Accuracy tolerance: Type ±0.3°C", "Long-term deviation: < 0.02 °C/year", "Operating range: -40 ~ 80°C", "Built-in humidity sensor: Resolution: 0.04%RH", "Accuracy tolerance: Type ±3%RH", "Long-term deviation: < 0.02 °C/year", "Operating range: 0~96%RH", "External lighting sensor: Based on BH1750 lighting sensor", "Cable length: 50cm", "Resolution: 1 lx", "Range: 0-65535 lx", "Operating range: -40°C ~ 85°C", "1 x Dragino LHT65S-EU868-E5 temperature, humidity and light sensor", "1 x External Light Sensor", "1 x External Antenna"]
