Product Details

KOX501 O2 Sensor

Name: UART Output Electrochemical Gas Sensor For Air Quality
Brand: kacise
Price: 1 USD

Product Description

KOX501 electrochemical gas sensor module uses electrochemical principle to detect the concentration of toxic and harmful gases such as CO, H₂S, NO₂ in the environment. The module uses RoHS electrode electrochemical sensor as sensing element (the specific technical parameters of the sensor are detailed in the data manual), and realizes the gas concentration detection under the control of sampling circuit, which has good stability and selectivity. This module adopts four-wire connection with the receiving terminal, and outputs the gas concentration signal through the UART bus, which is convenient for the user.

Features

Sensors are made of lead-free materials, in full compliance with RoHS standards;

• The service life of up to 5 years is much higher than the 2-year service life of traditional lead-based oxygen sensors;

• Insensitive to carbon dioxide, the output signal accuracy is not affected by carbon dioxide;

• Operates well at -40℃, lower than conventional lead-based oxygen sensors Limit operating temperature;

• Highly resistant to changes in environmental factors, temperature, humidity or pressure Mutation has little effect on it.

• Excellent linearity, stability and reproducibility in long term applications with excellent performance consistency.

Application

Air quality monitoring
Smart Buildings
Granary air detection
