LS-111

LoRaWAN™ Compliant Sensor Series - CO2 and Temperature & Humidity

Made by
GlobalSat WorldCom is a certified partner.

Description

LS-111 is designed to measure Carbon Dioxide (CO2), Temperature and Humidity by LoRa® long-range and low-power wireless connectivity. It is integrated LoRa® wireless technology, CO2 sensor knowhow and high-performance MCU solution for various IoT markets usage. With calibrated CO2 sensor module and compensated Temperature/ Humidity sensor integration, the data is ready for use. It is perfect for monitoring air quality in schools, office buildings, greenhouses, factories, hotels, hospitals, transportation lines and anywhere high levels of carbon dioxide are generated.
