Carbon Dioxide Sensor CO2 Transmitter Sensor CO2 Industrial Concentration Detection Module

1、Built‑in hardcover probe, waterproof and breathable film design at the probe, accurate measurement. 2、Black shield wire, waterproof, oil proof, strong anti ‑ interference ability, stable signal transmission. 3、Wall mounted exquisite appearance design, installation screws on both sides, simple installation, saving space. 4、The three parts of input power, induction probe and signal output of the sensor are completely isolated, safe and reliable. 5、It has the characteristics of wide measuring range, good linear degree, easy to use, easy to install and long transmission distance. 6、This transmitter is widely used in agricultural greenhouses, flower cultivation and other occasions requiring CO2 and temperature and humidity monitoring. Condition: Brand New Item Type: Carbon Dioxide Sensor Material: ABS Color: As shown in the picture Size: Approx.11x8.5x4cm / 4.3x3.3x1.6in Weight: Approx.232g/8.2oz Power Supply: 12-24V DC Carbon Dioxide Measurement Range: 2000ppm Average Current: <85mA Carbon Dioxide Accuracy: ± (50ppm + 3% reading) (25 °C) Nonlinear: <1%F·S Warm-up Time: 2min (available), 10min (maximum accuracy) Output Signal: RS485 standard Modbus Humidity Accuracy: ±3% RH (0%6RH-100%RH, 25°C) Temperature Accuracy: ±0.5°C (25°C) Humidity Range: 0%RH-100%RH Temperature Range: -40 ° C - 80 ° c Long-term Temperature Stability: ≤0.1 °C / y Long-term Humidity Stability: ≤1%/y Application: This transmitter is widely used in agricultural greenhouses, flower cultivation and other occasions requiring CO2 and temperature and humidity monitoring. Interface Description: Wide voltage power input can be 12-24V. When wiring the 485 signal line, note that the A/B lines cannot be connected in reverse, and the addresses between multiple devices on the bus cannot conflict. Wire color Description Power supply Brown Power supply positive (12-24V DC) Power supply Black Power supply negative Communication Yellow (gray) 485-A Communication Blue 485-B Installation Instructions: The sensor should be placed in a sheltered environment from the wind and rain. The wall is perpendicular to the ground at 90 degrees, keeping the vent hole of the sensor straight ahead to prevent water ingress. At the same time, in order to ensure the accuracy of the measurement, please install the carbon dioxide transmitter in a well ventilated position. 1 x Carbon Dioxide Sensor
