["DRAGINO LHT65S-EU868-NE117 Temperature & Humidity Sensor The Dragino LHT65S-NE117 Temperature and Humidity Sensor is a LoRaWAN sensor with a large range. Has a built-in temperature and humidity sensor and has an connection for an external temperature sensor. The LHT65S-NE117 allows users to send data and reach extremely wide ranges. Es bietet Spreizspectralkommunikation mit extrem großer Reachweit und hoher Störfestigkeit bei minimalem Stromverbrauch. Is eignet sich für professional wireless Sensor network applications such as irrigation systems, intelligent Zähler, intelligent Städte, Gebäudeautomatisierung etc. The external sensor LHT65S-NE117 uses the NIST-traceable temperature sensor TI TMP117A with an accuracy of 0.1°C in the normal temperature range. The LHT65S-NE117 has a built-in non-rechargeable 2400mAh battery that can be used up to 10 years*. LHT65S-NE117 is fully compatible with the LoRaWAN v1.0.3 Class A Protocol, it can work with a Standard LoRaWAN Gateway. LHT65S-NE117 supports the Datalog function. The data is recorded when there is no netzabdeckung vorhanden ist, and users can retrieve the sensor value later to ensure that no sensor value is lost. *The actual battery life depends on how often the date is sent. Due to the external antenna, the sensor can achieve better coverage than the LHT65N-NE117. ±0.3 °C (Höchstwert) from -55 °C to 150 °C", "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", "Optional external sensors", "Three-color LED for status display", "Data logging when network connectivity is interrupted", "Wireless alarm and security systems", "House and building automation", "Automatic meter reading", "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 temperature sensor: Silica gel cable", "±0.1°C (maximum) from -20°C to 50°C", "±0.2°C (maximum) from -40°C to 100°C", "±0.3°C (maximum) from -55°C to 150°C", "1 x Dragino LHT65S-EU868-NE117 humidity and temperature sensor", "1 x Temperature Sensor"]
