IOT-Lora Pressure Transmitter

WSP-1000L Series Wireless Pressure, Level, and Temperature Transmitter User Manual (LoRa-Based LPWAN Solution)

WSP-1000L series leverages LoRa technology, a variant of Chirp Spread Spectrum (CSS) modulation with Forward Error Correction (FEC).
This enables designers to bypass the limitations of traditional wireless systems, offering unprecedented performance in penetration and range while maintaining a battery life of up to 3 years.
