Product Specification

Methane And Carbon Monoxide Evaluation Module For TGS3870 EM3870B Description:

This module facilitates evaluation of the characteristics of the TGS3870 gas sensor for the detection of both methane and carbon monoxide. Testing is simplified by using a continuous output signal generated by this module. While the driving mode of TGS3870 involves a 20-second heater cycle for intermittent detection, sensor response is converted into a continuous voltage signal by the software contained in the module's microprocessor.

Notes:

1. Evaluation use only

This module is designed for evaluation of the TGS3870 sensor only. Please do not use this module for any other purpose.

2. Power supply

Please apply the specified voltage to CN1 Pin #1 pin for proper sensor operation and performance. If excessive voltage or reverse voltage is applied to the module, the module or the sensor may be damaged.

Please note that there is no protection circuit in this module.

3. VR1 and VR2

Please do not adjust VR1 or VR2. These items have been adjusted so that standard driving conditions are applied to the sensor. If they are changed, the sensor may be damaged.

4. Impedance of equipment connected to CN1

The input impedance of equipment connected to the CN1 must be more than 1MΩ in order to make precise data acquisition.
