LTC2-HT LoRaWAN® Temperature Sensor

https://www.aiotkart.com/web/image/product.template/18188/image_1920?unique=db8a001

The Dragino LTC2-HT LoRaWAN® Temperature Sensor is an industrial-grade temperature transmitter engineered for precise and reliable monitoring using 3-wire PT100 probes. Designed for demanding environments, the LTC2-HT converts PT100 resistance readings into accurate temperature data and wirelessly transmits them to an IoT server via the LoRaWAN® network (v1.0.3 Class A).

Supporting up to 2 independent temperature monitoring channels, the LTC2-HT enables dual-point measurement in a single deployment, making it suitable for industrial automation, cold chain systems, and food safety applications across India.

Powered by a high-capacity 8500mAh Li-SOCl₂ battery, the device supports long-term operation of 2–10 years, depending on reporting interval and network conditions. With dual internal 16-bit ADCs and factory calibration, the LTC2-HT ensures high-precision resistance-to-temperature conversion for accurate industrial monitoring.

Its wall-mountable industrial enclosure, flexible configuration via LoRaWAN® or UART, firmware upgrade capability, and battery monitoring features make it ideal for continuous remote temperature tracking.
