Product Specification

Product overview：

The gas sensor based on the infrared absorption principle has the following strengths: good stability, strong selectivity, no oxygen dependence, wide range of detection, long service life, long maintenance cycle, powerful anti-jamming capability, etc. It becomes the gas detection development trend and can rapidly replace gas sensor based on the traditional principle.

MPY20-CO2 infrared gas sensor is designed with the latest technology, and achieves the constant working current of sensor when adopting low power processor and infrared source to control the overall power consumption, to guarantee the power circuit is free from the current shock influence and the sensor runs more stably.

MPY20-CO2 sensor adopts the latest design algorithm, including the gas concentration algorithm, calibration algorithm, temperature compensation algorithm, humidity compensation algorithm, etc. The sensor adopts 32-bit core industrial-grade microprocessor, is rapid in arithmetic speed and wide in operating temperature range, coordinates the latest algorithm to guarantee the high efficiency, high accuracy, stability and reliability of sensor data operation, and is suitable for different work environment.

The minimum output value and maximum output value of analog voltage signal of MPY20-CO2 sensor are 0V and 2.5V, respectively. Users can configure the zero output voltage value, full-range output voltage value, output voltage deviation value, output mode, etc. with PC configuration software so that they can rapidly and flexibly adjust in such demand. The configuration parameters are kept after power outage.

Digital communication baud rate of MPY20-CO2 sensor can be set as 19200, 38400 or 115200 by users. The digital communication of sensor includes the active mode and passive mode. In active mode, sensor proactively and continuously sends the real-time measurement data as per the configured data transmission ion interval time (1-99S); In passive mode, the sensor sends the measurement data after waiting for the command about data reading at terminal in real time, and the configuration parameters are kept after power outage.
