Overview :

LAS-302V1 is designed to measure carbon dioxide, temperature, and humidity by LoRa long-range and low-power wireless connectivity. It is an integrated LoRa wireless technology, CO2 sensor and T/RH% sensor know-how and high-performance MCU solution for various IoT market usage. With a calibrated CO2 sensor module, compensated temperature and humidity sensor integration, the data is ready for use. Besides, with the ultra-low power consumption CO2 module, the wireless devices could be achieved, and it is convenient for installation. 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.

Features :

  • Support multiple air quality sensors (option)
  • Support PIR sensor (option)
  • Wireless transmission to server
  • Easy to replace the battery without special tools
  • Easy settings for user from web configuration
  • Support both battery and AC adapter power in
