Main features of the sensor

  • It uses NDIR technology to accurately measure CO2 concentration in the air
  • Measures air temperature and humidity, providing detailed environmental information
  • It is compatible with Modbus RTU/ASCII RS485 and SDI-12 communication protocols
  • It offers automatic sensor calibration by holding the button for 5 seconds
  • Perfect for use in a variety of environments such as greenhouses, laboratories and research stations
  • It has an IP65 protection rating
  • It is intended to perform measurements mainly in closed spaces

If attempting to install the sensor outdoors, appropriate shading measures are required to prevent damage to the device from direct sunlight and rainwater.

Communication protocols Modbus RTU / ASCII RS485 and SDI-12

RS485 is a data transmission standard enabling serial communication over long distances and in difficult environmental conditions . It is often used in industrial systems due to its ability to maintain reliable communication even in the presence of electromagnetic interference.

SDI-12 is an interface standard for connecting microprocessors with environmental sensors, where the number "12" means 1200 baud, i.e. the data transmission speed. It is particularly popular in environmental monitoring applications because it allows multiple sensors to be connected to a single data recording device simply and efficiently .
