LAS-302V1 CO2 T/RH Sensor
Overview :
LAS-302 series 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. LAS-302 series has two models, LAS-302V1 and LAS-302V2. They only differ in the CO2 sensor and corresponding power consumption. LAS-302V1 is designed as a low power consumption version with the S11 CO2 module. LAS-302V2 adopt the S8 CO2 module, it could only support AC adapter power-in. Customers can choose according to product needs. With a calibrated CO2 sensor module, compensated temperature and humidity sensor integration, the data is ready for use. Besides, with the 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
